Single Pressure Controls
Top quality and largest market share of pressure controls in China
Factory direct sale
Features
1. P/PC series single pressure controls can protect the compressors in refrigeration and air conditioning plants, keeping them from over-low pressure or over-high pressure.
2. P/PC series single pressure switches can start and stop refrigeration compressors and air condenser fans.
3. The P/PC series pressure controls are not only used in fluoride refrigeration, but also in air and liquid refrigeration
4. P/PC series low and high pressure switches are fit with 3 kinds of changeover switches: a single pole double throw, (SPDT), a double pole single throw (DPST) and a double pole double throw (DPDT).
5. The position of the switch is determined by the pressure control setting, and the pressure of the connector.
6. Available mediums: R134a, R22, R407C, R404A/507, R410A, air, water and oil under the viscosity ≤4°
7. Pressure control switch approvals: CQC (China), CE (Europe), RoHS (Europe), UL (USA, Canada)
8. Exportation to Europe, Asia, North America, South America, Africa, Australia, and the Middle East
9. OEM services are available
