The series of electric flange heaters type FHK-HYB offers a solution for heating hot water boilers or high pressure steam generators as single heater or in a hybrid boiler. The standard heater consists of a number of rod elements TIG welded into a process flange. A robust terminal box protects the electrical connections. The number of elements fitted depends upon the media to be heated and the kilowatt rating required. Dependent on application, the heater can be provided with temperature control by contactor or thyristor (OhmEx type SCH-HYB).
