We develop and supply a wide range of tubular electric heating elements.

In 1965 we brought tubular steel-armoured heating elements onto the market, revolutionising the domestic washing sector, which until then had been tied to the use of copper.

  • Available sizes (sheaths)
    4.5 mm to 16 mm

  • Available materials
    stainless steel, incoloy, inconel, cronifer, carbon steel, copper, titanium, special materials

  • Available lengths
    from 250 mm to 8,000 mm

  • Application sectors
    Energy, industrial processes, machinery and plastic processing, transportation, air conditioning, domestic heating, mass catering, vending machines, professional washing and ironing, beauty and wellness.

Widely established, tubular heating element technology employs a resistive wire immersed in compressed magnesium oxide and protected by a metal sheath.

The careful selection of raw materials and the strict quality standards governing Zoppas Industries Heating Element Technologies’ processes guarantee our tubular heating elements high quality, reliability over time (even at high temperatures and specific loads), chemical-mechanical resistance, and safety under any conditions.

Our quality laboratories systematically check the quality of the materials used, which are also guaranteed by a traceability system.

We supply tubular heaters in a wide range of powers, voltages, lengths and shapes. In fact, we make, by bending, the flat and three-dimensional geometries that best suit the customer’s application.

From simple U-shaped tubular heating element to coil, rectangular shape to helical shape, etc.

We make housings and connections for explosion-proof heaters for use in hazardous environments.

Our armored tubular heating elements are extremely versatile, suitable for a variety of applications and sectors: energy, industrial processes, general industrial machinery and plastic processing machinery, transportation, air conditioning and domestic heating, mass catering, vending machines, professional washing and ironing, and wellness.


Our tubular resistors are CSA and UL approved.
