These thru-the-side immersion heaters utilize standard pipe fl anges ranging from 3 to 14" nominal pipe diameter to support high tank pressures of superheated steam, compressed gases or liquids. They are installed through a matching companion fl ange (obtainable from local industrial supply houses) to the tank wall.
The electrical housing is separated from the flange by an air gap (six-inch standard) to lower the ambient temperature of the electrical wiring. This option is used on flanged immersion heaters where the flange temperature exceeds 482°F (250°C).
