Immersion heaters

An immersion heater by Heating Group International consists of three parts: the heating elements (tubular elements), the screw plug and the connection box. The heating elements are connected to the plug by soldering or TIG welding. Because of this construction a rather compact heating element is produced with an optimal heat transfer to the medium which requires to be heated.

What is an immersion heater used for?

Immersion heaters are being used for the heating of water, oil, air and a variety of other fluids and gases. The elements can be supplied with or without temperature control and safety thermostats in the connection box. The thermostats (both the control thermostat and high temperature thermostat) can be 1 pole or 3 pole devices. Immersion heaters can be supplied in nearly any power rating and voltage. We carry an extensive range of standard products of the most commonly used immersion heaters. These elements are available with screw plugs in stainless steel or bronze and in a number of standard inch sizes, like 1, 1.25, 1.5, 2, 2.5 and 3. The elements are standard available in Incoloy, nickelled copper, Inconel and Stainless Steel.

The design of removable immersion heaters

Removable immersion heaters are designed to heat liquid in open tanks with low or variable liquid level, such as in degreasing baths process or surface treatment. Adapted to process requirements and dimensional constraints, these removable devices allow vertical (wall) or horizontal (bottom) heating. For low-level tanks, removable immersion heaters consist of removable heating elements formed from tube Ø 6.5 – 8.5 – 10 – 16 mm equipped with an adequate non heated length. The electrical conductors connecting the heater to the electrical junction box, are inserted into a stainless-steel tube. This solution enables the coupling 1Ph or 3Ph, star or delta to be done in the electrical box.

Heating of very aggressive and corrosive areas

Next to the above mentioned tubular elements, removable immersion heaters can also consist of glass, porcelain, stainless steel or titan tubes fitted with ceramic elements. These elements are predominantly used for the heating of aggressive liquids. For this specific use, Heating Group International also offers Teflon coated immersion heaters especially designed for the use in very aggressive and corrosive areas.
