Liebert 1D15059P1S Pressure Switch 321894-709 resulting in smoother light-offs andThe Liebert 1D15059P1S is a critical 15 35# low pressure switch engineered specifically for precision cooling units and industrial HVACR systems. As a genuine OEM replacement part, this pressure control monitors the suction side of the refrigeration circuit to protect the compressor from damage caused by low refrigerant charge, restricted flow, or evaporator coil icing. With a calibrated cut in and cut out range of 15 to 35 PSI, it ensures the system
