Motor Heaters are the same as our Silicone Rubber Heaters in the standard sizes and configuration that is used in this industry and made the same way using resistance wire heating circuits laminated between thin layers of fiberglass-reinforced, high-temperature silicone rubber insulation. The thin profile transfers heat quickly. Silicone Rubber heaters are resistant to temperature extremes, moisture, weathering, radiation, fungus and chemical attack.

Motor Heaters help prevent moisture build-up in electrical motors by warming the motor’s electrical windings. Condensation occurs when humid air contacts the cooler metal of the motor, which, if allowed to collect over time, will corrode the windings, degrading motor performance and contributing to premature motor failure. Condensation prevention is especially critical for equipment operating in tropical environments where continuous humidity can quickly degrade an electric motor. Motor Heaters also provide warm start-ups, which helps extend motor life.

To install, simply wrap the heater around the inside motor housing. These heaters are not equipped with a temperature controller. If a Motor Heater is being used in a temperature-sensitive environment, a thermal device, such as a thermostat, should be used to ensure temperature control. They also do not have a grounding plane and must be grounded to prevent electrical build-up.
