Anti-Condensation Heater for Motor, SH, NORD DRIVESYSTEMS Order Code Example:SH-230V

Possible Applications

This anti-condensation heater is deployed in electric motors operating in environments subject to severe thermal cycling and high relative humidity, such as wastewater treatment plants, coastal pumping stations, and marine propulsion systems. In these settings, rapid cooling of the motor after a shutdown cycle creates a dew point differential that draws moisture into the stator windings, causing insulation breakdown and subsequent electrical failure. By maintaining a constant elevated internal temperature during idle periods, the heating element prevents internal moisture accumulation in equipment like outdoor conveyor drives, agricultural ventilation fans, and pulp and paper mill machinery. This preventative thermal management is particularly critical for standby or intermittently operated drives in refrigerated warehouses and outdoor aggregate processing plants, where ambient temperature drops would otherwise compromise winding integrity and shorten motor service life.
