Casings are produced in mild steel as standard with painting normally provided after manufacture although special finishes can be provided for apllications requiring extra protection.
Totally enclosed motors are fitted as standard to a minimum of IP55 protection for non-hazardous applications. For high temperature, hazardous area and secial installation requiremnets motors to the required specification are available.
