Finned Heaters

Screw-in Tubular Heaters are the standard solution for all heating processes with liquids or gas. The heater is installed in a tank or a tube system by the G1½" screw fitting. The IP54 connection head, fitting and tubular heater consists of stainless steel. The tube sheath material 1.4529 is resistant to sulphite, phosphors and hydrochloride media.

Square stainless steel tubular heaters BASE-flex (1.4541) are a reliable industry standard for the use in heating platens and manifolds. In contrast to traditional tubular heaters with a round section which have to be bent by machines, square BASE-flex can be fitted into any rectangular groove with simple hand tools. Moreover, the square shape results in a bigger heat emitting area of up to 80% compared with a corresponding round section. Finally, the easy manual mounting saves the usually high technical expenditure for casting-in / soldering / cementing of bent round tubular heaters. A soft version of the BASE-flex, the NICKEL-flex (2.4068) is available as special execution. Due to the soft, easy to form nickel material, the NICKEL-flex is suitable for manual mounting with hand tools in round sections, too. Furthermore, Nickel has a better capability to conduct heat compared with stainless steel.

Owing to their small cross-sectional dimensions, MicroCoils are most often connected at both ends and do not permit the addition of a thermocouple. We prefer to use nickel as the sheath material here because it combines the best thermal conduction properties, high corrosion resistance and excellent deformation properties. To ensure that the standard 1000 mm PTFE-insulated connection cable can be positioned at one end, despite the standard two-ended connection of the element, in most cases the MicroCoil is formed into a hairpin shape and wound/laid in a bifilar (parallel) format. Our unformed MicroCoils are also supplied in the hairpin bend shape as standard.

Open wire heating elements are the best solution for air heating when used in fans. Because of our longlasting experience in this field, we can offer you a series construction in most cases. To use our open wire or coil heating elements in air, the installation of a cut-out is necessary (heat accumulation). The connection is done by a plug at the element (Faston 4,8 or 6,3) or by a cord set. Our extended range of air heater variants comprises: -> Heaters for Laundry Dryers (series & spare parts types) -> Heaters for Cross Flow Fan -> Heaters for Powerful Radial Blowers -> Heating Crosses & Special Designs Various special designs for airflow heating, deploying heater spirals on insulating mica support, are available. They are required when the available space for installation is limited and defined geometrical air ducts do not exist. All special open wire heaters are individual designs, i.e. custom-made.
