Explosion-proof compressor motor for oil refinery

The failure of the previously installed compressor motor was causing enormous financial damage. The team of the German family business Menzel worked on this project with considerable commitment, including weekend shifts, and thus completed all necessary works in record time.

An in-stock MEBKSW-type three-phase squirrel-cage induction motor in size 710 was enabled for ignition protection type Ex ec, increased safety, with purging. Menzel’s certified explosion protection experts gave it the ATEX marking II 3G Ex ec IIA T3 Gc and prepared the extensive documentation required by the customer within the tight time frame.

The motor generates an output of 10 MW and 64132 Nm rated torque at 6600 V rated voltage. It features IP55 protection and IC 81W cooling (air-to-water heat exchanger) and is suitable for outdoor installation and the increased ambient temperature range of -20-48 degrees centigrate. To ensure a smooth installation in the existing plant environment, Menzel made various mechanical adaptations such as machining the motor shaft, manufacturing a new base frame and providing flanges for the purging device.
