Motor Heaters (MH series heaters) are designed to control moisture build-up on the electric motor windings. Condensation build-up in the motor can result in premature failure of the electric motor. Moisture condensation occurs when moist air comes in contact with the cold metal surface. Over a period of time the moisture deteriorates the electric windings in the motor. Flexible motor heaters provide heat to the electrical windings preventing moisture to collect in the motor.
MH series heater also benefits electrical motors by ensuring warm start-ups, extended bearing life and adds freeze protection to electrical motors.
