Flanged immersion heaters
These are particularly suitable for heating and maintaining the temperature of large volumes or heating circulating fluids such as water, heavy fuel oil, thermal fluid, air or gas. They can be fitted on tanks, cisterns, boilers and circulation reheaters and are the best electrical heating system for a range of industries such as food processing, chemicals, textiles & plastics etc.
The stainless steel or incoloy armoured elements are generally hairpin-shaped and are welded to the DIN/ASA standardized flanges according to procedures which have CODAP, TÜV and ASME approval.
The watt density, ranging from 0.1 to 15 W/cm², is determined from the working parameters of the process and the exchange coefficients. For a maximum immersion length of 3300 mm, the power delivered by a flange immersion heater can reach several MW.
The electrical cabling in one or more places gives access to several power steps. Connection blocks and rods are used to ensure the electrical connection.
The array may be fitted with a temperature control system whereby the power and specific load are controlled by parameters such as flow rate, pressure, viscosity, temperature etc.

High Performance Elements (THP)
CETAL bolt heaters are specially designed to deliver the maximum power to the heating part. CETAL has developed Boron nitride insulation based bolt heaters, to obtain watt densities that exceed 40 W/cm². These can be used indifferently for tightening / loosening of bolts, for thermal dilation of turbines, for pressure equipments, for drop-forge installations…
CETAL bolt heaters can be equipped with low-voltage connectors, cables, connection boxes, carrying handles. CETAL bolt heaters' technology allows heating to be achieved in a few minutes, thus reducing down-time of pressure equipments and installations considerably.

Manufacturing of very high performance elements is the result of the research and development carried out by CETAL during the period 1986 -1987.
This allowed the widening of the application perimeters of heating by the Joule effect which until then was by traditional armoured heating elements (insulation by electrical grade magnesium oxide).
The very high performances of these elements are directly connected to the control of the manufacturing process :
- Positioning of the heating wire as close as possible to the sheath whilst guaranteeing dielectric rigidity.
- Compactness of the insulation (boron nitride) allowing heat transfer and providing electrical insulation when hot.
Boron nitride is used as an electrical insulator to produce stainless steel or incoloy tubular heating elements (diameter 10, 16 or 19 mm). These one- or three-phased elements can be equipped with a core-integrated thermocouple. The watt density, which depends on the operating conditions (convection, conduction and radiation) and on the elements sheath temperature, can exceed 100 W/cm²
