Description
The Parker-Sporlan 903560P ADRHE-6 is an adjustable hot gas bypass regulator engineered to maintain stable system operation under varying load conditions in commercial refrigeration and HVAC applications. By diverting hot discharge gas back to the evaporator inlet, this valve prevents coil freeze-up and compressor short-cycling during periods of reduced cooling demand — extending equipment life and improving overall system efficiency.
Key Features
- Model ADRHE-6 adjustable hot gas bypass regulator
- Pressure range: 0–30 PSI (0/30#)
- Connection size: 7/8″ ODF (sweat)
- Adjustable setpoint for precise system tuning
- Designed to prevent evaporator freeze-up at low load conditions
- Reduces compressor short-cycling for improved reliability
- Robust construction for long-term field performance
Application
The ADRHE-6 is ideal for use in commercial refrigeration systems, air conditioning equipment, and process cooling applications where load variation requires active capacity control. Hot gas bypass regulators are commonly installed on systems with single-speed compressors to simulate reduced capacity without unloaders or variable-speed drives.
