Heating Jackets are employed in many areas of industry, in research, laboratories and experimental facilities as well as in production. They are used to heat, for example: columns, reactors, UHV facilities, valves, piping, flanges, containers, drums, gas cylinders, etc. Heat input takes place via a heat conductor which is either crocheted into a carrier material or sewn on. Our heating jackets consist of glass fabric, glass yarn or silicate yarn. The heat conductor is either crocheted in or sewn on following a meander-type pattern. Thermal insulation is ensured by an insulating layer adapted to the operating temperatures. A robust outer cover, chosen specifically for the existing ambient and operating conditions, provides mechanical protection.
