CSA Explosion Proof Repairs

TECO Westinghouse OPTIM TEXP Explosion Proof hazardous location electric motor

Beaver Electrical Machinery is a CSA Approved facility for repair of motors and generators for use in hazardous locations.

Explosion-proof motors are required to ensure that the external temperatures of the motor will not ignite vapour or dust and also to ensure that internal faults will be contained within the motor enclosure under all operating conditions.

Beaver can perform CSA Approved hazardous location repairs on a wide range of electric motors and generators. C Squirrel Cage, AC Slip-Ring, Single Phase, 3 Phase, and DC Motors.

We can perform hazardous location repairs on motors as large as 2000 HP and voltage class up to 6900 VAC or 1000 VDC. We are capable of working on equipment in this class up to 60 inches in rotating diameter.
