The P28 series lube oil controls provide dependable and economical oil pressure cut-out for pressure-lubricated refrigeration compressors. The field-adjustable pressure differential of these controls provides compressor operation according to the manufacturer's specifications. The P28 controls operate by measuring the net lube oil pressure and de-energizing the compressor if the pressure falls below the differential setpoint.
