Single pressure control

Detailed Product Description

P series single pressure controls can protect compressors in refrigeration and air-condition plant, and keep them from over-low pressure or over-high suction pressure.
P series single pressure controls can start and stop refrigeration compressors and fans of air condensers.

P series single pressure controls can be used not only in fluoride refrigeration,but also in air and liquid.
P series single pressure controls 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.
Approvals of P series single pressure controls : DnV,Det norske Veritas(Norway),CQC(China),CE (Europe).
