Supco SLP90120 Low Pressure Switch 90 Open PSI (CUT-OUT) 120 Close PSI (CUT-IN)

The Supco SLP90120 Low-Pressure switch is used to detect and control conditions of refrigeration and HVAC systems. It is activated at 90 PSI to avoid the possibility of working under low pressure, which is not secure, and deactivated at 120 PSI to get the opportunity to continue operating. It is installed on the low-pressure side of compressors or refrigeration loops to guard against failure of such components as compressors and evaporators due to inadequate flow of refrigerant. As an element of the system operation as a secure and control element, the switch stability in system operation.
