Defrost Drainers

The defrost drainer regulator is designed specifically for removing liquid condensate from evaporators during the defrost period. The oversize seat orifice is designed to quickly remove liquid. As hot gas is introduced into the evaporator, the gas is condensed and drains to the lower coil row of the evaporator and into the defrost drainer. The defrost drainer meters the liquid and a minimal amount of gas back to the intercooler or low-pressure receiver.

The defrost drainer offers the advantage of higher energy efficiency by not allowing unneeded hot gas to return to the suction and the unnecessary increase in compressor capacity and operation, and corresponding increase in suction pressures.
