Liquid-cooled three-phase line reactor 8% Uk
DESCRIPTION
Water cooled reactors are available with ingress protection ratings IP00 to IP65. REO can utilize 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.
