OVERVIEW WATTCO™ circulation heaters are the perfect solution for generating heat and enhancing normal immersion heaters performance. They are designed to heat pressurized circulating fluids to provide effective, controlled heating to water, oil, steam and other gases. Circulation heaters are composed of all-in-one units with a heater mounted inside an insulated tank. They are made of a flanged or a screwplug immersion heater that is inserted into a pressure vessel or a pipe body. Heaters have inlet and outlet piping where the liquid or gas goes through the tank in order to reach the desired...

CIRCULATION HEATERS immersion heaters GENERAL PRINCIPLES: »» The heat you get from an electric heater will leave the heater, as opposed »» »» to the steam or liquid heat exchanger. Even when the surface area in contact with the application is properly fixed, the sheath temperature of the heating element will increase until the heat achieved is similar to the heat that is transferred to the process. Low watt density heaters last longer than high density heaters, particularly with viscous or stagnant liquids. Low density heaters are however more expensive. For larger systems, please call us at...
