Motor Purge Controller

The Motor Purge Control System MPC consists of a Motor Purge Controller and outlet valve to allow safe operation of electric motors in hazardous environments through pressurized purging. The system monitors, controls, and regulates the supply of purge gas to explosion-protected motors, reliably reporting and deactivating motors in the event of faults or loss of purge gas supply. The MPC is available in variants for Zone 1 hazardous areas and Zone 2, and automatically functions to purge motors per programmed time intervals.

Motor Purge Control System MPC for Zone 1 and 2

Motor Purge Controller MPC

Features Description
 Automatically functioning Ex px purge system The motor purge control system consisting of an
for electric motors MPC Motor Purge Controller and an MPV Motor
Purge Valve (outlet valve) is a unit which allows
 Fail-safe control – SIL 2
the safe operation of electric motors in hazardous
 Purging/operation status display environments.
The explosion protection is ensured by means of a
pressurised enclosure with leakage loss compensa-
tion.
The Motor Purge Control System monitors, controls
and regulates the supply of purge gas to the Ex p
motor.
Any faults that arise within the system or during the
supply of purge gas will be reliably reported and
deactivated by a safe disconnection of the Ex p motor.
