Dual Pressure Controller

Detailed Product Description

P830 series pressure control can protect compressors in refrigeration and air-condition plant, and keep them from over-low pressure or over-high suction pressure.
P830 series pressure controls can start and stop refrigeration compressors and fans of air condensers.
P830 series pressure controls can be used not only in fluoride refrigeration,but also in air and liquid.
P830 series 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: DnV,Det norske Veritas(Norway),CQC(China),CE (Europe).
