Description
The Sporlan Controls 3937-00 is a 1-3/8″ three-way (3W) hot gas defrost valve engineered for dependable performance in commercial and industrial refrigeration systems. Sporlan’s hot gas defrost valves are a trusted solution for efficiently managing the defrost cycle by redirecting hot refrigerant gas directly to the evaporator coil, eliminating frost buildup without the need for electric resistance heaters.
How It Works
During a defrost cycle, the 3-way valve diverts high-pressure hot gas from the compressor discharge line to the evaporator, rapidly melting accumulated frost. This method reduces defrost time, lowers energy consumption, and minimizes temperature fluctuations within the refrigerated space — protecting product quality and extending equipment life.
