Hey guys, Martin King, it’s your process chiller Pro here today. And I wanted to share with you what we’re gonna be talking about today. And today we’re taking on the subject of hot gas bypass. Now many of you probably know if you buy process chillers that the manufacturer that builds them, they assemble a bunch of components that they’re buying from other vendors or putting them into a box, and they’re creating a chiller for you. And most of them the good ones, they’re going to pre test all of their equipment before they ship it to you. And that’s a good thing. What you may not know is a lot of them, if not, most of them will test their machines using just water. So they’re going to test the machine at 4544 degrees setpoint running straight water, which means all the controls, especially the refrigeration controls are set up for water. And if you’re running a process that’s 45 degrees, he’s no problem, especially if you’re in a climate that doesn’t require glycol, most likely, if you do the basic on startup, you’re going to have children, that’s going to work just fine. But if you have an application that requires glycol, you’re running in a low ambient condition and you’re running colder than 45, then your chiller is going to have to be set up to run at these lower temperatures. And it will require a technician in the field to set it up correctly. So hot cast bypass, which should be a standard feature, and I’ll discuss that later on the episode. That should be a standard feature on a process duty chiller will have to be adjusted based on your operating conditions in the field. If you don’t do it, what’s going to end up happening is you could potentially have customers complaining that they’re not getting the capacity that they purchase from you. Or worse than that you could have a situation where you have a freeze up, that turns into a lot of issues up to and including damage to the chiller. So adjusting hot gas bypass and properly setting your machine up is super important. So I’m going to show you how to do that in this episode.

It’ll really help fill in the gaps. Now I will do my very best as I’m going through this content to try to explain what I’m putting up on the screen. However, sometimes I just can’t do that good of a job at it because it tends to be a little bit technical. So make some time to do that. Lastly, if you’re into the HVAC, trade or skilled trades, and you’re learning about new stuff that I’m providing on these videos, I want to remind you that this content is really designed for people who are skilled trades people you’re in other words, you’re comfortable with refrigeration, you’re comfortable with electrical and you have a good amount of common sense not to get yourself into situations where you can get yourself hurt. So my suggestion is if you’re carrying out one of the things that I’ve described in any one of these videos and you’re feeling a little bit uncomfortable, stop and find somebody with a little bit more experience to help you do these tasks that I’m talking about. So that’s my keep it safe guys. suggestion. Well Without further ado, let’s jump into this new episode of the process chiller pro podcast.

In this episode, I’m going to be talking about two topics that have to do with a hot gas bypass in a process chiller application. First, I’m going to be talking about the orientation of a hot gas bypass regulator within the refrigeration cycle. So we’re going to go over that I’m going to show you a quick review of a basic refrigeration system inside of a process chiller and I’m going to show you how the hot gas bypass is orientated within that system. The second thing I’m going to be covering is how to properly set up a hot gas bypass regulator to properly run within a process chiller. Now, if you saw the intro to this particular episode, I touched on one of the facts of the industry that most manufacturers will ship chillers that are tested, which is a good thing. However, they’re not tested using glycol, they’re typically tested using water. So the safety controls the hot gas bypass, everything is oriented orientated for water, which is a 32 degrees freeze point. And they usually tested at nominal conditions 95 degree ambient or less usually in the factory, and 4445 leaving the chiller, which is great for testing and still gets the job done. However, if the chiller gets delivered, and the application requires glycol, meaning that the outdoor ambient temperature can get sub freezing or the process loop temperature, the approach temperature to the process is below 45, you’re going to have to run glycol, and the hot gas bypass regulator system. And the controls which is something we’ll talk about in other episodes are not set up that way. So the result is if you go ahead and start up a chiller, and you don’t need glycol, you have warm ambience you have above 45, you’re probably going to be 100%. Okay, but in the large number of cases that are running glycol, you will have to adjust the controls and you will have to adjust the hot gas bypass system to run correctly under your design conditions. If you don’t do that, there’s some relatively bad things that can happen. What I mean by that is endless service calls. If you do a start up and you don’t set up the hot gas correctly, you’re going to have service calls like the customer complaining they’re not getting enough capacity, or worst case scenario, the evaporators freezing up causing the chiller to go down ultimately end up with a really stressed out customer, perhaps damage to the relationship. Worst case scenario you ice up the evaporator so bad it cracks in it fails, which turns into a catastrophic problem in some cases, where it may be actually cheaper to replace the whole chiller than it is to repair it. So some bad things can potentially happen. Before I switch over to our first phase looking at the refrigeration system and how the hot gas is orientated. I want to make a suggestion that you check out two episodes of the process chiller pro podcast. The first one is what’s the difference between a air conditioning or comfort cooling chiller versus a process chiller. We did this episode A while back, it had really great reviews, and it covers a lot of stuff. So you can really get your head around the differences between an air conditioning duty and a process duty chiller. The second one is evaporator isotopes. So I get into some detail as to how isotopes occur, and things like that. And it’s relevant to this particular episode, because one of the main reasons for a hot gas bypass is to act as a backstop against freeze ups. And I’m going to get into that a little bit later. But if you check out those two episodes, it’s going to really give you a good framework to consume what I’m going to be covering in this particular episode. Now in the show notes for this episode, there’ll be two links, probably other links too, but I will provide links to both of those episodes on the process, chiller academy.com website and you can jump over and look at those episodes directly. I recommend if you can checking those out ahead of time before you watch this particular one or after two if it works out for you. As I mentioned, we’re going to do a quick

review of a process Chiller Refrigeration system. And as I mentioned before, we’re going to do that and then we’re going to look at the deployment or the orientation of a hot gas bypass system within that refrigeration cycle. We’re going to look at this starting at the compressor. And whenever you’re looking at a refrigeration system, it’s always a good idea to start at the compressor because it’s usually the most prominent or very obvious to see within the refrigeration cycle. So that’s what we’re going to start I’m going to review this First as a regular refrigeration system, and then I’m going to dive into the hot gas bypass application. So off the compressor, we have a hot gas line. So it’s high pressure, high temperature gas coming off, and it’s going into our air cooled condenser. And then it leaves the condenser after. So you go from a high pressure gas to high pressure liquid, it goes down here through your liquid line. So we have a filter dryer, we have a moisture indicating site class, we have a liquid line solenoid, and then we have an externally equalize thermostatic expansion valve or T XV. So we come up here, it goes into our brace plate refrigerant to liquid or fluid heat exchanger, and then it comes out of that heat exchanger into our saturated suction line. So as it goes in, it’s a lower pressure liquid and it starts to boil off it creates a temperature difference between the fluid going in on one side of the heat exchanger and the refrigerant which is colder. So you have second law of thermodynamics, we have a heat transfer into the refrigerant, it exits the refrigerant goes out of the evaporator as suction, low pressure, gas or saturated suction, and then it falls and then it falls along here into our accumulator. If any of you guys want to know what an accumulator does for you, I’d be happy to do an episode on that just let me know. And then it comes out of the accumulator into our scroll compressor. So that’s the normal cycle, if you will, without a system or system without a hot gas bypass application in it. So off the compressor, we’ll go back to the compressor now. So you’ll notice there’s a t here. So when you have a enabled or equipped refrigeration system with hot gas, you’re going to see a T. So one direction, which we already covered goes into the condenser, the other direction goes into what I call the hot gas bypass line.

So the first thing that we see along this line here is a hot gas solenoid. And the purpose of that is to delay deployment of your hot gas bypass regulator valve until the until the compressor has a chance to run. Now we set these up for a 92nd delay. So 90 seconds after our compressor starts, you’ll hear it click in the hot gas bypass solenoid will open and that allows hot gas up to the inlet of the regulator valve. So the regulator valve has three pipes as inlet outlet. And you’ll also see a sensor tube that goes up to our saturated suction line and its whole purpose in life is to measure pressure in this suction line because that’s what actuates this valve, the lower the pressure below whatever this valve is set for. And we’ll get into this in a minute, the more gas that gets deployed through it. So the higher is your pressure goes above whatever your regulator valve is set for, then that valve will close. So that’s basically how this thing operates. So following along t that goes between the outlet of your expansion valve and the inlet of your evaporator. So when that valve is deployed or starts to regulate open, you’re rejecting or injecting excuse me hot gas directly into your line that’s feeding your evaporator. So that’s how that works. Now, before we get into more detail here, I want to dispel with a couple myths and inject my opinion into a few things. So there’s two arguments about why you want to have a hot gas bypass system in or in a process chiller. One is, which I think is the most important is it acts as a backstop against ice up. That to me is the primary goal of a hot gas bypass system in one of these chillers. The secondary item, which I believe is minor, is you get capacity control out of it. Now the reason why I say so you control out of it. Now the reason why I say it’s minor is because there’s so many other technologies out here out there today that are much, much better. Two that come to mind is VFD control of your compressor. Much much better for capacity control. And then you have other technologies like digital scrolls that are also good to actually change the capacity of your compressor. And the reason why those are better Is there a lot faster reacting now we have a lot of PLCs that have the ability to read data in super quickly. And you can especially when you use PLCs running VFDs and you have electronic expansion valves I mean you can do some amazingly quick capacity control with that. So using hot gas bypass is capacity control is really old school and I would argue is not the primary reason why you want that’s the that’s my my short argument on that. Now there’s two things that can happen in a hot gas bypass not being set up correctly. As I touched on earlier, most manufacturers of process duty chillers, they don’t make all the individual individual components, they make the sheet metal, they buy their TX, V’s Their condensers, their evaporators they buy from all these different vendors and they basically package it and putting into put into a chiller they build something out of it. So most likely when you receive a chiller, the hot gas bypass regulator valve is set up on its default settings. Because most manufacturers, as I mentioned earlier, will test and the testing is good. But they will not adjust these to what the customer plans on operating that the chiller out in the field, they just don’t have the settings you’re going to find is exactly how that valve on your regulator valve left Sportline or whoever manufactured it. So it does have to be at the very least checked. But it does need to be calibrated for the operating conditions for this particular chiller. The two extremes are if it’s set to deploy too soon, the complaint you’re going to get from the customer is I’m not getting any capacity out of it. And why is that? Well, because you’re dumping hot gas directly into the line feeding your evaporator, which essentially is taking away your capacity. So you’ll have a upset customer. They’re gonna say, Man, I just spent all this money on a chiller and I can’t keep up with the load. I can’t tell you how many times we had tech support calls come in on that front to just find out that the hot gas bypass was set up with its default settings. And it was just dumping hot gas in there. So that that’s that extreme extreme. The other extreme is it’s set up to deploy too late. So if you have a system where even if you are running glycol, you have a system where it’s not set up correctly, and somebody goes to the PLC and sets the compressor to run lower than it should. That means that the in the hot gas bypass is not set to deploy soon enough, you have the setup for freezing up and evaporator. And there’s a whole bunch of bad things that can happen in that respect. As a side note,

if you haven’t checked it out already, if you go to process, chiller Academy comm you go to the blog, vlog link at the top of the page, you’ll see that I have a whole episode of the process Tiller pro podcast covering how freeze UPS happen, how they, you know the process that that causes them. And it’s should be very helpful. So if you did so doubt, I think it’d be very educational talks about glycol, refractometers, all that stuff. So I would check that out. So you could potentially have an ice up. And it’s that’s bad. There’s there’s a bunch of things that could happen there. So what I’m going to do now is I’m going to get into how to properly calibrate these things. Now, you can make this really complicated if you really want to, you can get your Tp charts out you can do you can really spend a lot of time calibrating these things, I’m going to give you a solid way to do it, how I’ve instructed technicians do it for years. And in my opinion, it’s the best way. And I want to run you through how to do that. So you’ll need a couple things before you get started. One is if you have help, that will be really helpful. And it’s a little redundant, but that it would be super, super helpful to have somebody there to help you. And the reason why is there’s physical The reason why is there’s physical locality issues where you have to be messing with the valve. And you it’s also very helpful to have a set of eyes on the PLC to see where your actual fluid temperature is versus your setpoint because the magic happens when your fluid temperatures getting about a degree or two away from your setpoint whatever that is. So get some out. Second thing is you’ll need a pair of channel locks, you’ll need a allen wrench set, ideally a long stem allen wrench set that’s in good condition. And the most important thing you’re going to need is a calibrated digital thermometer, a clamp on style. So something you can clamp around a pipe and actually read the temperature of the fluid or excuse me, not the fluid, the refrigerant going through a pipe that’s very helpful, ideally digital because you need something that’s fast reacting. So as soon as there’s a change in that line temperature, boom, you can see it. I would go the clamp ons. There’s a lot of them out there, but you want to make sure you’ve got one good Operating conditioner you’re going to waste a lot of time. So all that being said, let’s take a look real quickly at the actual valve itself so I can give you a little orientation on what you’re actually looking for here.

So I put up on the screen what these valves look like, again, for you driving around you guys driving trucks out there, check it out on video, it’d be very helpful, but I’ll try and describe what you’re looking at here. This is a image of a Spurlin hot gas bypass solenoid valve, I think it’s spotland. Pretty sure there’s an inlet outlet and little tube in the front here is your sensor tube. And as I mentioned earlier, that goes up to your saturated suction line. So one, the inlet will come from your hot gas solenoid valve. Ultimately it comes from the output of your compressor, high pressure gas, and the outlet is going to go to a tee that will take you to the line going between your T XV outlet and your evaporator inlet. So that’s that’s how this plumbed. So there’s a little hat looks like a hat like a top hat. And that hat is the adjustment of at the very top of the hat, you’re going to have a brass typically dust cap of some type. Now this dust cap is just there to do what it does to keep contaminants out of the inside of the valve. You’ll need per channel ox, as I mentioned earlier, to get it started, there’s an O ring in there. So once you give it about a half a turn three quarters of return, you get the threads up past the O ring, and you can spin the rest of it off with your hand down inside, you’re usually about halfway down because they’re normally set at the factory about halfway, you’ll see your hex where your Allen will go. So what you want to do is you want to get your clamp on connected to your line your your outlet line to this valve and you want to get the cap off, you want to get your Allen wrench in there before you start. That’s just get everything all set up. That’s that. So I’m going to flip back over to our drawing here. And there’s our there’s our valve orientating the system. So right here about six inches or so from the outlet of your regulator valve, you want to have your clamp on, you’ve got your cap off, you get your Allen wrench in there. Now it’s time to start your system up. Now what you want to do if possible, is and this is what I used to do is when you finished all your your pre checks and there’s a whole list of things you want to do on a process chiller to get it ready to start, you’re going to have your glycol in, you’re going to have your no leaks, you’re going to be ready to go in, you are going to be ready to start it up. And what I like to do is I’d like to start my pumps, I’ll raise my setpoint so your compressor does not run. I’ll start my pumps up and the friction in the pumps while you’re doing a lot a lot of your you know talking to the customer or whatever. Depending on your conditions the the operating of the pumps will generate friction but you’re up a bit so that’s what you want to do. Ideally you want to be about eight to 10 degrees warmer than whatever the customer setpoint is so you have a good long run when you fire up your compressor. So we’ll get the compressor started now and the first thing you should see go over to your PLC you should see that your temperature starting to drop because your refrigeration is doing its thing. 90 seconds or so. After your compressor starts your hot gas will open. Your regulator valve on the inlet will be exposed to hot gas. And as that temperature comes down of your fluid going into your evaporator your suction pressure will also begin to drop. So what you want to do is you want to get on your Allen wrench and you want to make adjustments to it and your hole goal is to see on your thermometer, you want to see that the valve is just starting to open just as you get to your setpoint. So for example, if you have a 40 degree setpoint, you’re going to need to open or close this valve depending on where you know where it’s at, to open right at about 41. So when you see 41 degrees, you want to adjust, you want to get on that Allen wrench and you want to see that your outlet temperature based on your probe is just starting to bump up, that gives you the indication that that valve is opening. And that’s your sweet spot. That’s it, that’s all you have to do. Once it’s set up, it’s set up you’re in great shape. And that is, that’s how you do that.

Now I’m going to jump over here to a document that’s provided by this manufacturer. And I’m going to show you some other information that you should have, if you’re not familiar with the particular valve you’re working on, should have olton, 90 dash four, one, this is for spoil and now but all the manufacturers will provide these documents. Most likely this document did not get shipped with your chiller. Most manufacturers, they’ll take the part out of the box, they’ll plumb it in the box and the paperwork and all that and usually end up in the trash. So the good news is you have your phones with you these days and getting this information is really easy. All you have to do is get the information off the valve, punch it into your browser and look it up and you can get the download within seconds. What I want to do here is I want to run you to there’s a lot of data here by the way that you could you could this is good midnight reading on page three is probably the most valuable information on this entire document, at least from what you’re doing when you’re trying to do your calibration. The first thing I’m showing here is a direction of turn. This little paragraph here is very helpful to know. It says a clockwise rotation increases the setting and account o’clock wise look, rotation decreases a setting. Now most valves work that way because they’re working against a spring, but not all. So you want to know that. So when you’re cranking on your Allen wrench, you want to know which direction is open or closing this valve. So that’s a very helpful piece of information right there. The other thing that’s helpful is this table just to the left, this is on page three of document, 90 Dash 41 is there’s a table here it has all the different valves that’s covered on this particular bulletin. And a particular valve we’re working on is a zero to 100 psi valve. So what this is talking about is the range of suction pressure that this valve is designed to measure on its sensor to that’s that tube that runs from the valve up to the suction line. So this is a zero to 100 psi suction valve and you can have anything in there. The next column here is the standard setting. So what they’re saying there is, it makes sense, right? It’s about halfway Remember, I mentioned that the positioning is usually about halfway. So zero to 100 psi valve, the standard setting on that is 50, right, but halfway between 100 and zero. So when that thing leaves the plant, if the pressure drops below 50, that valves opening, it rises above 50, it closes, and there’s a bandwidth of a few PSI. So on the open side, if it gets below 50, it’ll start opening and it’s going to be completely open, probably 4748, something like that, maybe 45. So it just depends on the valve. So that’s a helpful piece of information. So you’ll know, when you get that valve, most likely, that’s where it’s going to be set. So if you’re running glycol, you may want to just before you even start the killer app, you may want to fill her up, you may want to make it set up where it’s fully closed or just hit it down a little bit. So it’s not open when you start your test. So eat that yet. The other piece of valuable information here is this column will tell you what your psi per turn is. So every 360 degrees turn on that Allen wrench on your adjustment is equal to about 16 psi and this is not rocket science. It could be anywhere between 14 and 18. Okay, but it’ll give you a really good idea. So you know if you you know if you’re looking at your Tp char if you want to go that far, and you know for sure that you don’t want this valve to open while you’re doing your initial test. You may want to give it two turns which right it’ll drop it down 32 psi below your 50 right so you can get started with it in a fully closed position so you get the idea what I’m talking about here. So that’s a really helpful and gets you through the calibration process of your hot gas pressure. regulator

Okay, so let’s get on to viewer questions for today. The first question I have is from Mike in Grand Rapids, Michigan. And Mike wants to know how I come up with the topics for the process Tiller pro episodes. Great question, Mike, thank you for asking that when I’m going to kind of give you a Reader’s Digest. When I was running my process, Tiller manufacturing company, Legacy chiller systems, I was very frustrated at times, because I wanted feedback on what people thought about our product and services. And it was very hard, I had a hard time doing it. We tried everything we tried phone calls, emails, even some incentives where we would send customers hats, and pens and cups and that kind of stuff. And we can never get consistent feedback. So I get frustrated. And right around that whole time, there was a TV show out there called Undercover Boss, I’m not sure if you remember it or not. It was I think it was a pretty big hit. And I watched a few episodes of that, and it inspired me, I’m going Wow, I wonder if I could do something like that. So I started doing tech support calls, I started taking phone calls from customers, not telling who I was just random, hard ones, easy ones, whatever. And I made lists of the types of questions and problems that customers had. And I took that one step further even to go out in the field, I would show up on customer sites that we didn’t have a lot of relationships with or just you know, onesie twosie customers, and I would go out there and just show up and work with the just a factory representative in the area wanted to see if I could help out with a startup we there was no money exchanged is basically showed up, fired all over the place. I went all over the continental US even some places, places in Canada. And I got some great feedback from face to face. And some of them was kind of harsh. I’m working with these contractors. And they were giving me some pretty harsh advice on what they thought, which actually, in turn ended up with some changes that we made to some of our process Tiller design. So that is how I get a lot of my content. It comes from these lists that I’ve produced over the years. However, I’m trying to get feedback from folks like you. So if there’s process Tiller questions, refrigeration questions that you have, get them out to me, and I’ll provide a little resource for you to do that at the end of the show. But that is how I do that. And I’m very responsive to trying to help folks out there. The second and final viewer question was from Fred Collins, Jr. This one came in over LinkedIn. He’s a field supervisor in the Greater New Orleans area. I like that area. That’s a great area. So let’s see, Fred says, Good listen, I guess he listened to the podcast, you mentioned adding an extra plate to the heat exchanger. Do you not have the chiller package engineer? Great question. during commissioning, always right inside the cabinet, the flow and temperature design for further reference. You are confusing me with the approach temperatures. You mentioned the approach temperature I’m familiar with is the temperature difference in the refrigerant and the liquid and the leaving liquid. The the lower the approach to to more efficient or cooling heating medium versus medium being cooled or heated. So little confusing, but I know what he was getting out there. The first the I’m going to answer all those right the engineering design on a process chiller. Yes, absolutely. The difference between a designing for a process chiller versus an air conditioning duty chiller is a process chiller has a huge variety of operating conditions. And I touched on this in a podcast I mentioned earlier in this episode, and I’ll provide a link to that in the show notes. We have an episode that talks specifically about the differences between the two. But yes, when we designed a chiller, we wanted to know the customer’s operating conditions, the glycol percentage, they need to run for the area, especially if it was a an application that we were not familiar with. If it was an MRI or a brewery or something like that. We already knew what those operating conditions are. So all we had to do is look at the ambient conditions for that particular location. Right. But yes, we was always selected the evaporator and the compressor to work together. And then in a lot of cases, if it was a good customer of ours, we had a system some of ours we had a system sizer tool that I designed based on Excel. And what it does is it calculates your pumping requirements and it even does offsets for glycol. As a side note, if you’re interested in that we actually have a course on that and I’ll talk about courses in a minute. But we have that particular piece of software available that’s included with one of our training courses. So something to check out the other question that he had, that had to do with writing the conditions down, that’s an easy one, you always that’s a great idea. Because you never know if you know if you’re going to be the next guy out there, if there’s information about the operating conditions of that particular chiller, particularly stuff that you did, it’s always a really great idea to put your flow rates and set points and write it down inside the cabinet. And determine approach, this is a really great one, I get this all the time. So the term approach came into play. I remember it because I’m old, but I remember it when it came into when section 608 and all this stuff with refrigerants, environmental and all that kind of stuff. The term approach, you’re 100% Correct. That the the term approach, Fred had to do with the difference in the saturated suction temperature versus the medium. However, when it comes to process chillers, I started using it because a lot of the mechanical engineers that I work with started using it. And customers seem to understand what I’m talking about when I say approach process approach is how I termed it, it’s the temperature of the fluid medium going to their process. So that’s just something that I’ve always done. And just like many things, Fred, in this industry, there’s always a couple different ways to talk about a couple different things. And I could go on all day about that, but you are correct. However, in the process, chiller area approach is also used for fluid temperature going through the process. So that wraps up the listener, mail segment, I would invite you if you have any questions that are process chiller related to send me a message on LinkedIn or send me an email at M King at process Tiller Academy comm make sure if you want to get on the air with me that you mentioned your name and town and give me all your contact information. Assuming you’re emailing me, I’d like to get that from you. And if you do not want your name mentioned on the show, just let me know that and I’ll connect up with you directly.

So this is a new block that I wanted to give a try out to I had one of our listeners asked me about my thoughts in this area. So I’m gonna start this new block. This is called words, terms and quotes. So this particular quote comes from Steve Jobs, the founder of Apple, and I thought this was pretty cool. Your work is going to fill a large part of your life. And the only way to truly be satisfied is do what you believe is great work. And the only way to do great work is to love what you do. I think that’s awesome. So hopefully that inspires you a little bit to have a great week. Before we wrap up this episode, I want to share with you some exciting stuff that we have going on in the process, chiller Academy comm website. All of this stuff is happening on the technician resource page that I’m putting up on the screen now. So check it out, if you get a chance to watch this in video mode. The first thing I want to share with you is I’m super excited about this program. This is a skilled trade Success System. And I’ve developed this over the last 30 years. And what we’re doing to try it out is I’m putting together a five day free email course that covers the Success program. Now, this is not a technical course. Basically what I’m teaching you in this free course is the mindset and the habits that are needed to be successful in the industry. I cover technical excellence, I cover work ethic, I cover personal finance, although I don’t get into investing or anything like that. And I also cover the all important work life balance. Now one of the things I’d like to share with you is I have been training my technicians for years with this when I was a contractor all the way up. Through the years I’ve been working with my technicians with this and many of the technicians that I’ve used this particular program for have either continued in the industry and many of them are technicians making well into the six figures. Many of them have actually started their own businesses or are millionaires now. So what I want to do share this with you guys in hopefully allow you to apply these skills that I offer to your lives in speed your trajectory as you’re working through the skilled trades. And this doesn’t just apply to HVAC refrigeration. The second thing I want to share with you is the courses that we have for sale on this page. Now right now we only have three we have maintenance, we have chiller system design, and we have basic refrigeration and troubleshooting of refrigeration systems. And for limited time I’m going to be offering 25% off any one of these courses. And all you have to do is use the promo code Code Chillar pro at checkout and you’ll get you’ll get in, the additional bonus that I’m offering to everybody out there is you’ll have access to me. So when you register for your course, you’re going to get an email. And then email is going to have a link to register for my office hours. So I dedicate a few hours each week to spend time with my students and help them through the course content and answer any refrigeration type questions that I possibly can. The other benefit is if you have stuff that’s outside my skill set, let’s say you need help and controls or you need help and boilers I’ve been in the business a very long time. So what I try to do doesn’t happen every time but what I’ll try to do is connect you up with some of the pros that I’ve worked with before that really know their stuff. So that’s one of the things that you will only get as a paid student. Now if you use the promo code you’re access to my office hours goes for a period of one year starting from when you purchase it. So you got a whole year of direct support one on one from me so hopefully that will help you out
