Anti-condensation Heaters for Electric Machines

 

Our anti-condensation heaters are U L– CSA approved

The anti-condensation heaters provide low cost protection against the formation of condensation in rotating electrical equipment. They are strongly recommended for use in electric motors, generators and alternators that operate in humid conditions, such as offshore applications, marine equipment, overhead cranes, borehole pumps and for all machines that operate in tropical environments.
Miotti’s heaters consist of 5 separate heating filaments covered by a protective layer of silicone rubber and soldered together at the terminals. It is completely covered by a braided glass fibre sleeve and then covered with adhesive tape made of the same material. The cold ends are made of FEP.

The special design of Miotti’s heaters makes them ideal for class F and H applications as well as for electric machines that are subjected to vibration or shock. Their -60° to + 200° temperature range allows these products to be used even under extreme conditions.
Miotti’s heaters are installed around the base of the winding heads before or after impregnation. Care must be taken to cover at least three quarters of them – if the element selected is longer than the circumference of the head, avoid overlapping the ends and leave a distance of a at least 5mm in order to avoid localized overheating.

The characteristics of our heaters are as follows:

  • Temperature range -60°C / + 200°C
  • Dielectric strength 2.5 kV / 10s
  • FEP UL 1330 AWG 20 (200°C / 600V) leads

All products in our warehouse are UL approved
