P830E Dual Pressure Control : Used on refrigeration compressors to control the suction and discharging pressure.

P830E pressure control can protect compressors in refrigeration and air-condition plant, and keep them from over-low pressure or over-high suction pressure. P830E pressure control can start and stop refrigeration compressors and fans of air condensers. P830E pressure control can be used not only in fluoride refrigeration,but also in air and liquid. P830E pressure control is 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,
