Description
The Supco SLP2045 Low-Pressure Switch is designed to measure and regulate refrigeration in HVAC systems. It is opened at 20 PSI to avoid working under the low-pressure conditions, which are not safe, and closed at 45 PSI to restart normal operation. It is installed on the side of compressors or refrigeration lines to cushion the constituents of the compressors and evaporators against destruction due to a lack of flow of refrigerant or loss of pressure. The switch is a safe and control element, which ensures the stable work of HVAC and refrigeration components.
