Detailed Product Description
P series single pressure controller 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 controller can start and stop refrigeration compressors and fans of air condensers.
P series single pressure controller can be used not only in fluoride refrigeration,but also in air and liquid.
P series single pressure controller 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 controller : DnV,Det norske Veritas(Norway),CQC(China),CE (Europe).
