Threaded Heaters

Our threaded immersion heaters are composed of tubular elements welded to a screw cap, which can be screwed to a threaded inlet placed in the tank wall.
The electric heating elements are built with selected Ni Cr 80/20 wire, placed in the center of a metal tube, and insulated with high quality magnesium oxide (MgO), compacted by cold drawing.

The sheath of the elements is generally made of one of the following materials: carbon steel, stainless steel 304 (L), 316 (L) or 321, Incoloy 800 or 825, Inconel 600 or 625, Titanium, Copper, Monel, or other materials available.

The elements are bonded, by welding or brazing, to a threaded screw cap, available in a variety of materials for different element sheath types and applications.

The screw cap can have BSP, NPT or ISO thread. Special threads and materials are available on request. The heaters can be equipped with a control thermostat and / or a manual reset safety thermostat.
