High pressure cut-out

High-pressure cut-outs are fitted to all hut the smallest of systems. The compressor outlet pressure is brought to one side of a bellows or diaphragm, and balanced by an adjustable spring. A scale on the control indicates the pressure setting to commercial accuracy and is checked on commissioning the system. 

HIGH SIDE - Parts of the refrigerating system subjected to condenser pressure or higher the system from the compression side of the compressor through the condenser to the expansion point of the evaporator. HIGH-PRESSURE CUT-OUT - Electrical control switch operated by the high-side pressure which automatically opens electrical circuit if too high pressure is reached.
