Description
The Trane SWT03793 Hi-Pressure Control GRA is a pressure safety part used to monitor refrigerant levels and protect equipment in HVAC systems. It operates by opening the circuit at 650 PSI and closing at 550 PSI, allowing the system to shut down under excessive pressure and restart once safe conditions return. This control is typically installed in air conditioning or refrigeration units, where it connects to the compressor circuit. Its role in the system is to prevent harm from high-pressure conditions, supporting safe and stable operation.
