Liquid and gas coolers are available in ten standard sizes through a capacity range of 15 to 1000 tons of ammonia refrigeration. Designed for installation in the booster discharge line, the gas and liquid coolers sub cools liquid ammonia from the receiver for the low stage load while desuperheating booster discharge gas to the high stage compressor. Desuperheating of booster discharge gas is necessary to prevent overheating of the high stage compressor. Sub cooling of liquid refrigerant for the low stage load is essential to obtain economical thermodynamic efficiency of the refrigeration cycle. Our gas and liquid coolers performs both of these functions efficiently.

Receivers are available in 26 standard models with an internal gross volume of 4.4 to 329.1 cubic feet and a pump down capacity of 130 to 9740 pounds based on 80% of internal volume with liquid refrigerant at 90° F. Ammonia or fluoridated receivers are made from carbon steel shell and carbon steel dished ends. Shells up to 300 mm (12") are made from seamless or welded pipes and above 300 mm, they are made from rolled plates. 

Range : The diameter vary from 200mm(8") to 1200mm (48") and the lengths vary from 1.5 Meters(5') to 7.5 Meters (25').
