Trane SWT2982 Dual Pressure Switch

The Trane SWT2982 Dual Pressure Switch works as an essential safety part in HVAC systems that protects Trane units like chillers and air handlers. The Dual Pressure Switch checks both high and low refrigerant pressure in the HVAC system. This system operates with two separate switches which turn on or off at their dedicated pressure levels. When the refrigerant pressure moves outside its safe operating range the switch system will stop the equipment to avoid damage to the compressor. The system protection stops the compressor from running to save its parts.
