Liquid-cooled chokes

Reducing the volume of construction with
liquid-cooled chokes

With the help of liquid cooling losses are derived specifically about the cooling circuit - and not in the environment.

By use of liquid cooling, the temperatures in the components can be reduced greatly -
ie less stress for the insulation materials and longer life.

Advantages of liquid cooling in chokes.
- Low surface temperature
- Increased service life
- Reducing the volume of construction

    Watercooled chokes are available are available with ingress protection ratings IP00 to IP65. REO can utilise several methods of water cooling these components. This provides controlled conduction of heat losses, ensuring that the local environment is not heated. Water cooling ensures that component temperatures are greatly reduced, reducing component stress and increasing product life. REO technology provides excellent heat distribution, preventing the emergence of so-called hot spots.
