Space Heater/Anti-Condensation Tool

Insta Control Pvt Ltd India offers a Space Heater/Anti-Condensation Tool. This is strip shape flexible heater having protective fibreglass sleeve on it. It is mainly used in electric motors and generators. The space heater/anti-condensation tool is used when it is necessary to evaporate condensed water on windings of electric motors and generators. This prevents the failure of electric motor and generator windings. Normally these heaters are tied on the winding overhang before impregnation and hence form integral part of the winding. This achieves maximum heat transfer. Motors, generators and alternators, which operate in high humidity, cold temperature climates and tropical conditions, require this type of heaters.

In case of extreme temperature variations also a space heater/anti-condensation tool should be fitted. The water condensation on winding occurs only when the electric motor is turned off and enclosure temperature drops rapidly to below the dew point or suddenly motor is turned on in damp or wet condition, this results in winding failure. The space heater/anti-condensation tool prevents the condensation of water inside the motor body when motor is not running. Use of space heater/anti-condensation tool at the design stage can save the expense of costly rewinds and down time, which is more precious. Then space heater/anti-condensation tool shall not be energised when the motor or generators is in running condition. Heater length should be taken such that it covers at least 75% of the winding overhang circumference. If heater length is more than circumference, it is very important to see that it does not overlap. The next turn should be separated from the original turn by at least 5 mm to avoid short circuit between two ends.
