Heating cable

Heating cable

Heating cables and tapes are one of the most versatile product lines in the our range. Available in a vast array of technologies, the range is surpassed by none. We offers a variety of heating tapes and cables to give fast and efficient direct contact heating. They are suitable for a wide range of applications from simple frost or condensation protection through to process requirements up to 1000°C.

Where space is tight, heating tapes are the perfect solution, allowing high temperatures to be reached quickly and maintained on pipelines, containers and other irregular shapes. In addition pre-terminated tapes are available in a variety of popular lengths, ready to install and easy to use requiring no special skills or tools.

 

Technology

Constant wattage tapes : These flexible and rugged tapes are constructed from parallel resistive cores insulated with various materials from silicone to quartz glass. Strict manufacturing tolerances ensure these heaters have a uniform element resistance, and due to the relationship between current, resistance and power, they deliver a constant, predetermined power density along the entire length.

 

Mineral insulated heating cables

Mineral insulated (MI) heating cables and units are rugged, long lasting and suitable for extreme conditions for example, to 1000˚C for very low vacuum/high pressure (or 600˚C for EX applications). They are constructed from a metallic tube and a conductor which is supported and insulated from the tube with an inorganic insulating powder, magnesium oxide. The conductor is usually Nichrome 80/20 although other materials such as copper and ferry can also be supplied for specific applications. The most common sheath materials are 321 stainless steel and Inconel 600, copper and cupronickel are also available.

 

Various methods can be employed to connect the MI heating element to the cold lead cable such as brazing or silver solder, however, no method offers the same temperature rating or proven longevity as that of the laser-welded cold lead joint developed and employed by Isopad. A significant improvement on previous jointing techniques, this laser welding provides a totally mechanically secure joint. As the welding is done at lower temperatures, heat stresses to the sheath material and the danger of the main failure mechanism of moisture ingress is avoided.

 

Applications for the Automotive Industry

Car seat heating

Heating patches glued or stitched onto non-woven fabrics for initial fitting or retrofitting.

Steering wheel heating

As in car seats, heating patches glued or stitched onto non-woven fabrics are applied, which can be customized to the shape of the steering wheel and therefore neatly incorporated.

AdBlue® Heating / Hose heating

The automotive industry represents one of the sectors where liquids are used that have a freezing point slightly below zero. Hose heating is required so as to prevent this point from being reached.

 

Applications for Housing Technology

Gutter heating

Both gutter and downspout are heated up to avert icing

Trace heating

Water pipes are heated up to avert icing and a consequential rupture of the pipe. Chemical and industrial processes also invite trace heating and self-regulating applications.

Floor heating

Heating cables on backing fabrics placed underneath hard flooring materials (tile floors, parquet etc.) or else woven into heating pads that lie on the floor like a carpet
