Indirect immersion heaters
Can be changed without discharge of the liquid
These immersion heaters are designed for indirect heating of liquids (water, oils, emulsions) in tanks or vessels for applications in every condition, especially heavy duty. Beside the standard types we can supply special types of heaters as per costumer's demands in short terms and without quantity limitations.
Heaters consists of ceramic cartridge placed in stainless steel protective tube. It means that the ceramic cartridge is separated from the liquid. Protective tubes can be installed in tanks in two ways: direct welding to the wall of the tank, or by flange connections (using flat or threaded flanges welded at the end of tube). Electric contacts can be protected with caps, housings or boxes. On protective caps there are cable glands for power cables.
The main advantage is in fact that ceramic cartridge can be replaced without removing tube with flange from the housing of the tank or vessel. This enables that when changing heater, there is no need to take out liquid from housing.

Protective cap material:
Diameter of tube: Ø33.7, Ø38, Ø50.8, Ø60, Ø70mm
Ceramic cartridge: Ø30, Ø32, Ø46, Ø54, Ø64mm
Threaded flange: G1¼", G1½", G2", G2¼", G2½
Tube is welded to the wall of the tank
For vertical instalation, resistantce coil should be skewed, which protects coil from loosening and falling due to own weight.
For horizontal instalation, it is recommended that protective tube with heater should be placed in vessel's bottom zone.
Heater must be always immersed into liquid.
