Description
The Trane CNT1584 is an OEM low pressure control engineered for reliable refrigerant circuit protection in Trane HVAC and refrigeration systems. Designed to monitor system low-side pressure, this control opens the circuit at 7 PSI and closes it at 22 PSI, safeguarding the compressor and refrigerant circuit from dangerously low pressure conditions that can result from refrigerant loss, evaporator icing, or restricted airflow.
Key Features
- OEM Trane replacement part — direct-fit for compatible Trane equipment
- Low pressure cut-in (open) set point: 7 PSI
- Low pressure cut-out (close) set point: 22 PSI
- Protects compressor from low refrigerant charge and loss-of-charge conditions
- Helps prevent compressor damage due to inadequate lubrication at low pressures
- Designed for use in refrigerant circuit monitoring applications
Application
The CNT1584 low pressure control is intended as a direct OEM replacement for Trane residential and light commercial air conditioning and refrigeration equipment. It integrates into the refrigerant circuit to continuously monitor suction-side pressure, tripping the system offline when pressure drops to the open set point of 7 PSI and automatically resetting when pressure recovers to 22 PSI. This automatic reset function helps restore normal system operation once the low-pressure condition has been resolved.
Why Choose the Trane CNT1584
- Genuine Trane OEM part ensures proper fit and performance
- Precise pressure set points maintain system integrity and compressor longevity
- Automatic reset operation minimizes downtime after pressure recovery
- Essential safety control for maintaining efficient, reliable HVAC operation
