Premier Evaporative Precoolers

CARRIER 125 TON CONDENSING UNIT

THIS IS A TYPICAL ARRANGEMENT FOR A 125 TON CARRIER AIR COOLED CONDENSING UNIT WHICH IS LOCATED IN A DEATH VALLEY RESORT. THIS UNIT DOES NOT MEET DEMAND DURING EXTREME TEMPERATURES WHICH IS COMMON FOR THE AREA.  INSTALLING PRECOOLING IS A GOOD WAY TO OFFSET THIS LOSS IN OUTPUT.
