This product help protects against refrigerant loss or excessive air conditioning/refrigeration compressor system pressure. A pressure switch closes an electrical contact when air compressor fluid pressure rises or falls. An air pressure switch is connected to a bellows or diaphragm that reacts to system pressure. The compressor’s press switch can automatically shut down the compressor when the pressure gets too high, to prevent damage to the AC system. We also other HVAC equipment, including, refrigeration test equipment, AC conduits and refrigerant lines,AC cleaners and scale removers, and other AC and refrigeration accessories.
DLP series pressure control can protect compressors in refrigeration and air-condition plant,and keep them from over-low pressure or over-high suction pressure.
DLP series pressure control can start and stop refrigeration compressors and fans of air condensers.
DLP series pressure control can be used not only in fluoride refrigeration,but also in air and liquid.
DLP series pressure control are fitted with 3 kind of changeover switch:a single pole double throw(SPDT),a double pole single throw(DPDT)and a double pole double throw(DPDT).The position of the switch is determined by the pressure control setting and the pressure at the connector.
