Hot Gas By-Pass Regulator


Emerson ACP  Valve

The main purpose for adding Emerson Hot Gas Bypass (HGBP) to any system is to prevent condensate from freezing on the surface of the evaporator coil when the system is operating at extremely low load conditions.  The Hot Gas Bypass valve is controlled by suction pressure, and its set point should be adjusted as low as possible to limit the amount of gas being bypassed and to minimize the negative effect of HGBP on the operating cost of the system.
