Description
The Trane SWT2982 Dual Pressure Switch is a essential safety component within HVAC systems, specifically designed for Trane equipment like chillers and large air handlers. This switch monitors two distinct pressure levels, typically high and low, within the refrigerant circuit. It operates by opening or closing electrical contacts based on these pressure readings. If the system’s pressure exceeds or falls below pre-set thresholds, the switch triggers, shutting down the equipment to prevent damage. This dual-functionality allows for comprehensive system protection against both over-pressurization and loss of refrigerant.
