Industrial immersion heaters are medium capacity heating units designed to heat liquids, viscous fluids, forced air and gases inside tanks, vessels and pipes. Screw plug electrical immersion heaters are designed to be immersed directly into the gas or liquid being heated; since these heaters come into direct contact with the gas or liquid, heat-up times are very fast.
Immersion heaters manufactured at consist of a single or a set of tubular elements that are formed into hairpins and welded or brazed to a screw plug.
The sheath material of the heating elements could be
The standard screw plug sizes utilized are 1”, 1 1/4, 2” and 2 1/2” and are either made of steel, brass or stainless steel, depending on the application. Various types of electrical protective enclosures, built-in thermostats, thermocouples and high-limit switches can be incorporated into screw plug immersion heaters.
