York S1-025-33451-000 Refrigerant Pressure Controller 23/38 PSI O/C

The York S1-025-33451-000 Refrigerant Pressure Controller is an used pressure control device to control pressure in HVACR systems for optimum performance and safety. This controller works under the pressure of 23 PSI for opening and 38 PSI for closing, thus suitable for use in controlling refrigerant pressure for most HVAC applications. The controller maintains the refrigerant pressures within the above limits which minimizes system failure, conserves energy, and increases HVAC equipment durability. It is applied in the HVACR systems to measure and manage pressures used in a refrigerator. If pressure increases or decreases beyond some specific levels, the controller turns on or off the relevant equipment, thereby maintaining the pressure as desired.
