This video is about a Walk-In Unit i installed and on a little about how a refrigeration pump down system works. The unit i perfer to install for wine walk-In coolers is Cellarpro. Compared to a few others i tried this unit is quieter, fan speed is adjustable & controls humidity very well. Enjoy!!
Thank You
