Electric air heaters are regularly used in industrial process technology, air-conditioning and process engineering as well as in the construction of industrial furnaces and drying plants. In addition to avoiding emissions, electric heaters are characterised by their high thermal efficiency and low maintenance requirements.
Depending on the existing or required system design, they are specified as rectangular duct air heaters, tubular air heaters, flanged air heaters or – in case of increased system pressure – as classic continuous flow heaters. The computer-supported construction optimises the design based on the flow velocity, the maximum permissible pressure loss and the surface load of the heater. Attention should be paid to the monitoring of the medium temperature and heater to avoid overheating of the system if the flow fails. Depending on the application, different electromechanical or electronic measuring and control units, or even individual thyristor and contactor controls, are available for this purpose. The housings are made from stainless steel or steel and feature a degree of protection of up to IP66. Tubular heaters with diameters of 8.5mm, 11.5mm or 16mm made from materials selected according to the medium’s corrosiveness serve as heat source. Versions including fans, transport rollers and own controller can be provided for mobile use.
We have been successfully engaged in electric heat technology for more than 25 years and have internationally developed and manufactured reference solutions for the chemical, mechanical and plant engineering industry. We specify and manufacture our products according to international standards (DGRL 97/23/EC, AD2000, EN 13455, ASME) and, if required, with approval by TÜV/GL/DNV etc.
