Product Description Specifications low Pressure Switch can protect compressor in refrigeration,and keep them from over-low pressure or over-high suction pressure.

Features: 1)water pressure switch can protect compressors in refrigeration and air-condition plant, and keep them from over-low pressure or over-high suction pressure. 2)water pressure switch can start and stop refrigeration compressors and fans of air condensers. 3)water pressure switch can be used not only in fluoride refrigeration, but also in air and liquid. 4)water pressure switch are fitted with a single pole double throw (SPDT) changeover switch. The position of the switch is determined by the pressure control setting and the pressure at the connector. 5)Approvals: DnV, Det norske Veritas (Norway), CQC (China), CE (Europe). Technical data:
