Pneumatic Refrigeration Equippment

Single pressure controller can protect compressors in refrigeration and air-condition plant, and keep them from over-low pressure or over-high suction pressure.
Itr can start and stop refrigeration compressors and fans of air condensers.

And it can be used not only in fluoride refrigeration, but also in air and liquid.
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.
Micro pressure control is an electrical switch controlled by pressure signal. It's affected by the discharge pressure of the compressor. When the discharge pressure of the compressor exceeds the setting pressure the control, it willcut out the power supply and product the system from undue pressure.
