These flexible heaters which many refer to as Anti-Condensation heaters, provide low-cost protection against the formation of water droplets caused by condensation in electric motors. Frequently used not only in electric motors but in alternators that operate in humid conditions, such as offshore applications, borehole, marine equipment, pumps, overhead cranes and for all machines that use in tropical applications.

The superior design of MEC’s heaters makes them ideal for class F and H applications as well as for electric machines that operate in harsh environments with a lot of vibration. Their -50° to + 190° temperature range allows these heaters to be used even under extreme conditions.

Install the heater on the stator coil before and also after impregnation—cover at least 75% of the windings. If the heater selected is longer than the circumference of the stator, avoid overlapping the ends and leave a distance of at least 6mm to avoid localized overheating.

The characteristics of our heaters are as follows:

  • Temperature range -50°C / + 190°C
  • Dielectric strength 2.5 kV / 10s
  • FEP UL 1330 AWG 20 (200°C / 600V) leads

All flexible heaters are UL approved.
