1. The P dual pressure control can protect compressors in refrigeration and air conditioning plants, keeping them from over-low pressure or over-high suction pressure
2. The P series high and low pressure switches can start and stop refrigeration compressors and air condenser fans.
3. The dual pressure switch is not only used in fluoride refrigeration, but air and liquid cooling as well.
4. The pressure switch is outfitted with 3 changeover switches: single pole double throw (SPDT), double pole single throw (DPST) and double pole double throw (DPDT).
5. Available mediums: R134a, R22, R407C, R404A/507, air, water and oil under the viscosity ≤4°
6. Pressure control switch approvals: CQC (China), CE (Europe), RoHS (Europe)
7. Exportation is carried out to Europe, Asia, North America, South America, Africa, Australia and the Middle East
