Heat tape and heating cable

As a global provider of electrical heat tracing solutions, eltherm offers a wide range of heating tapes, heating cables and trace heaters for various industrial applications. In most cases these are actually for freeze prevention or temperature maintenance. Due to the different designs of the outer jackets, we can cover temperatures of up to 900 °C* with our heaters. 

Which insulation covers which temperature range?

• FEP (Fluorinated Ethylene Propylene) up to 200 °C
• PFA / PTFE (Perfluoroalkoxy Alkane / Polytetrafluoroethylene) up to 260 °C
• E-glass (E-Gglass fibre) up to 450 °C
• Quartz glass (Quartz glass fibre) up to 900 °C*

*For high-temperature applications, let our application engineers advise you without obligation.

Parallel constant wattage heating cables with resistance wire (for example ELP/Si) consist of 2 supply conductors embedded in a first insulation. Wrapped around with the heating conductor, which is surrounded by a second insulation. The corresponding protective braid and the outer jacket provides maximum safety. For example: Typical applications are food industry for heating various pipes, vessels or valves as freeze prevention or temperature maintenance. The required nominal power output is calculated on the basis of various specifications, such as supply voltage, minimum and maximum ambient temperature and maintain temperature.

Series resistance heating cables can be cut to length (e.g. ELKM-AG-L). The design of this heat cable type is based on a stranded or spirally wrapped heat conductor which is covered by the insulation. On top of this this insulation is a protective braid (e.g. ELKM-AE). To ensure a higher mechanical protection, there are variants with an additional outer jacket available (e.g. ELKM AG-L). 

Heating tapes are mainly used for applications that require high flexibility and power output. The design is similar to the series resistance cable, with the difference that they are placed double inside an additional insulation and can therefore also provide more power output. Due to their design, heating tapes are more resistant and optimally protected while at the same time being particularly flexible. They are often used for electrical trace heating on tanks and vessels.

In general, each heating cable and heating tape is operated with appropriate measuring and control technology. As an alternative without temperature control, we can also offer various self-regulating heating cables. We will be happy to advise you in order to find the best solution for your application!
