Danfoss 034N0084 CPCE 22 Hot Gas Bypass Pressure Regulator 7/8 Inch ODF 0-85 PSI

Description

The Danfoss 034N0084 is a hot gas bypass regulator designed to maintain stable evaporator pressure and prevent excessively low suction pressure in refrigeration and air conditioning systems operating under reduced cooling loads. Featuring a 7/8-inch connection, it regulates the flow of hot discharge gas into the low-pressure side of a compatible refrigeration circuit. Its pressure-responsive mechanical operation helps stabilize system performance and reduce the risk of evaporator icing during low-load conditions.

Technical Specifications

Information About 034N0084

The 034N0084 is a Danfoss mechanical refrigeration pressure regulator intended for hot gas bypass applications in commercial and industrial cooling equipment. Its valve construction is designed to respond to changes in downstream pressure, adjusting refrigerant bypass flow according to system operating conditions without requiring external electrical power. The regulator is installed in a properly designed bypass line connecting the compressor discharge side to the low-pressure portion of the refrigeration system, with installation requirements determined by the refrigeration circuit. It is used in compatible compressor and evaporator arrangements where capacity reduction, suction pressure stabilization, and low-load temperature control are required.

Key Features:

• Hot Gas Bypass Regulation: Controls discharge gas bypass flow to support stable refrigeration operation under reduced cooling demand.

• Evaporator Pressure Stabilization: Helps maintain the required low-side pressure as evaporator load decreases.

• 7/8-Inch Connection: Features a nominal 7/8-inch connection for integration into compatible refrigerant piping.

• Mechanical Pressure Control: Operates through refrigerant pressure changes without an external electrical supply.

• Low-Load Operation: Supports refrigeration systems operating below their normal cooling capacity.

• Evaporator Freeze Protection: Helps reduce the likelihood of evaporator icing caused by excessively low operating pressure.

• Compressor Operating Stability: Supports consistent suction-side conditions during changing cooling demand.

• Automatic Valve Modulation: Adjusts bypass flow in response to pressure variations within the refrigeration circuit.

• Refrigeration System Integration: Suitable for compatible commercial refrigeration and air conditioning installations.

• Industrial Valve Construction: Designed for installation in pressurized refrigerant circuits using appropriate connection and sealing procedures.

The 034N0084 delivers the reliability and precision required for hot gas bypass regulation, evaporator pressure stabilization, and refrigeration capacity control during variable cooling loads.
