Tubular Heaters


Careful selection of raw materials and the strict quality standards regulating Zenun Industries processes guarantee our sheathed tubular elements top quality, reliability over time (even with very high specific temperatures and charges), chemical-mechanical strength and safety under all conditions.

In particular for the sheath, which must stand up to thermal and mechanical stress and corrosion, we offer a wide choice of standard diameters (6.25 to 16 mm) and materials: stainless steel, Incoloy, inconel, cronifer, carbon steel, copper, titanium or special materials.

Zenun Industries provides tubular heaters in a large range of power, voltages, lengths (300 to 8,000 mm) and shapes. We bend the elements into flat or three dimensional shapes that are the most suitable for customers’ applications: simple U shaped heating elements, serpentines, rectangular or spiral shapes, etc.

Sheathed tubular heating elements are extremely versatile and suitable for several applications and trades: energy, industrial processes, industrial machinery in general and machines for plastics, transport, air conditioning and domestic heating, catering, vending machines, professional washing and ironing machines and wellness.

In synergy with our customers we develop and produce a wide range of tubular heaters: plain, finned, cast assemblies, suitable for immersion or complex heat exchanger systems (flanged or duct heaters). The heaters can also be assembled with different elements (connections, flanges and threaded attachments) and fixing systems (coining, TIG welding, brazing).
