Description

Motor Purge Control System consisting of a Motor Purge Controller - MPC and a Motor Purge Valve - MPV (outlet valve) is a unit allowing a safe operation of electric motors in a hazardous environment.

The explosion protection is ensured by means of a pressurised enclosure with leakage loss compensation. The Motor Purge Control System monitors, controls and regulates the purging gas supply for the Ex p motor.

Any malfunctioning in the system or the purging gas supply will be reported reliably and deactivated by safely isolating the Ex p motor.
