Electric Immersion Heaters are most suitable for direct heating of nearly all process liquids and corres- ponding applications.

Excellent chemical resistance is ensured by the use of different immersion tube materials and variable fitting options help you to meet the individual re- quirements of heating installations.

A long life span with optimum reli- ability is assured by using high qual- ity materials thereby ensuring fault- less operation of your system.

Electric Immersion heater is constructed on a modular basis and consists of a tube, a long-life heat- ing cartridge, a terminal casing and the lead.

The Immersion Heater Tube

We can offer you the optimum ma- terial for every application. The heated length (minimum immersion depth) is marked by a ring which is generally two-thirds of the tube length. The tube is not heated above this mark. The heated portion must always be covered with liquid even in the case of high liquid level fluc- tuation.

The Long-Life Heating Cartridge

Long-life heating cartridges are made from ceramic groove bodies with high electrical insulation values and good mechanical strength.

A high temperature resistance heat- ing wire is fitted as a coil in order to achieve the best possible heat radiation from tube to liquid. The cartridges for immersion heaters are available in rated power voltages up to a maximum of 500 volts for one, two and three phase connections.
