Single-Pressure Refrigerant Controls

Available115 products

Single-pressure refrigeration controls connect to a refrigeration system's high- or low-pressure line and monitor the line pressure. They have contacts that change their state when the trigger pressure is reached, allowing the control system to respond to pressure changes and prevent hazardous or inefficient conditions.

Single-Pressure Controls

Single-Pressure Controls
Single-pressure controls connect to one of the two pressure lines in a refrigeration system and make or break an electrical connection when pressures exceed or drop below the setpoint. They feature a control unit that helps protect the sensitive components and allows the user to view and adjust the setpoint. They are commonly used with the low-pressure side to control the compressor and act as a low-limit safeguard. They can also act as an overpressure safeguard on the high-pressure line.
