HELIOS tubular heating elements offer numerous technological benefits. These include high levels of operational safety, dielectric strength, contact and moisture protection, good heat conduction and thermal conductivity, low thermal absorption, good deformability, high stability, shock resistance and long service life.
High performance tubular heating elements, diameter 8.4 in accordance with DIN 44874 comprise a spiralled heating element with welded-on M4 connecting bolt, embedded centrally in a highly-compressed insulating compound made of magnesium oxide and protected by a bendable metal tube.
The tube ends are closed off with sealing ceramic end caps.
Depending on the application, heating conductors are NiCr 3020 or NiCr 8020.
Up to 690 volts
Depending on application
A table for determination of the maximum surface load and tube sheath material can be found on page 9.6 of the product leaflet. Please get in touch with us. We will be glad to advise you.
