We have been manufacturing top quality sheathed heating elements. In 2016 we launched onto the market steel sheathed tubular heating elements and revolutionized the domestic washing machine.
Well consolidated, tubular technology uses resistivity wire in compressed magnesium oxide protected by a metal sheath.
Careful selection of raw materials and the strict quality standards regulating the Caldor Industries Heating 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.
We provide 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.
We also manufacture cases and connections for explosion-proof heaters installed in explosive environments.
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).
