Trafotek is a pioneer in bringing out innovative cooling systems which help to achive the desired product size, weight and thermal impact on the environment. In fact, Trafotek has been one of the first companies to develop indirect liquid cooling to reactors.Trafotek manufactures liquid cooled reactors with direct and indirect construction. Liquid cooled reactors are often used in demanding applications like marine and windmills where space is restricted and where liquid connections are commonly available.

Liquid cooling enables effective and compact transfer of heat losses from electrical premises. Also reactor size can be reduced up to 70% compared to reactors with natural air cooling.


  • Small size.
  • Robust and strong construction.
  • Up to 90% of losses to liquid with indirect cooling.
  • Up to 98% of losses to liquid with direct cooling.
  • No service needed.
  • Low pressure drop.
  • High overload capability.
  • High pressure and temperature withstand.
  • Variation to different applications and materials.
