SFHK flange heater
Siekerkotte flange heaters/immersion heaters SFHK are used in industrial processes for the direct heating of liquid, gaseous or solid media up to approx. 5MW. To install the heaters in existing pressure vessels, basins, pipelines, etc., these components are individually adapted to meet the power requirement and process conditions.
Here, too, we offer a standard program for heating water up to 320kW that is available at short notice.

Structure and material
The heaters are made of high-density tubular heaters, which are optimized and designed for the respective heating process (tube material, shape, diameter, unheated area, arrangement). A customer-specific design ensures that the solution takes into account all characteristics of the medium (corrosion, surface stress, etc.), vibrations and other process specifications. Design and manufacture is carried out according to DGRL 97/23/EG, AD2000, EN13455, ASME.
The flange heaters and the blind flange can be made from different materials (1.4571, ..., 2.4858, etc.) depending on the medium to be heated and ambient conditions. The connection housing is thermally insulated. When the temperature of the medium exceeds 150 °C, additional insulation is installed between the blind flange and the connection housing to protect the connection terminals and lines. If required, baffle plates and segments are designed to increase flow velocity of the medium in the flow tube.
The heater is monitored and controlled during operation. For this purpose, mechanical or electronic temperature controllers and/or limiters, PT100, thermocouples, individual thyristor and contactor controls are used as stand-alone control systems or as signal transmitters for an existing PLC.
