WELDING TECHNIQUES USED IN HEATING ELEMENTS FOR ELECTRIC HEATERS

Electric immersion heaters provide a vital source of heating in industrial applications by quickly raising the temperature of the heating medium.

Their robust, compact, and uncomplicated design makes them a method of choice whenever industrial heating requirements arise.

Immersion heaters are efficient, economical in terms of initial investment and total cost of ownership. As well as offering a fast method of heating the fluids in tanks and vessels. They can directly heat the fluid by inserting the immersion heater in the vessel with direct contact with the fluid.

Alternatively, immersion heaters can use an indirect heating mode where a secondary heat transfer loop in the vessel heats up the heat transfer fluid. This heats the fluid in the tank through an inline heat exchanger. This indirect method of heating is usually preferred where the fluid to be heated is detrimental to the heating element or the sheath element of the immersion heater.

In the direct method of immersion heating, the fluid reaches the desired temperature quickly. It can accurately maintain that temperature for longer periods of time.

Made of heating elements encased in the sheath material molded in the shape of a bundle the immersion heater can either be screwed on the side of the vessel or have the flange mounted based on application nature.
