Description
The Carrier P251-0083C is a Head Pressure Control, an essential component in the Carrier HVAC systems to control the head pressure and safeguard essentialequipment. This device size is relatively small, with dimensions of 5.6” L x 7.4” W x 2.4” H and a voltage of 120V to 480V. It controls the amount of refrigerant discharged by the compressor at any time. By regulating this head pressure the control guarantees that the system runs optimally and no high pressure is created. High pressure can put a lot of pressure on the compressor and thus can lead to faster wearing off of the compressor. The control assists in avoiding evaporator coil freeze-ups and low-pressure cut-outs hence avoiding system breakdowns.
