Flanged immersion heaters consist of hairpin tubular elements welded or brazed into an ANSI pipe flange & provided with wiring boxes for electrical connections.
Be sure the element sheath material & watt density is compatible with the medium being heated. Listed below are the most common flange sizes, however, other sizes and watt densities are available. We have the capability to design and manufacture to your specifications, with a minimal lead time.
High Watt Density flanged immersion heaters Heater:
Flange heaters are used in industrial water boilers and storage tanks. The steam boiler heaters feature the highest quality, high nickel Incoloy sheath that provides the highest practical protection available against hard water containing minerals, scale and salts while resisting stress, corrosion, cracking, and sulphur attack.
With 20 years experience, Superb Heater is your trusted source for quality high watt density flanged immersion heaters heater as one of the leading suppliers of various heaters in China. Providing you with the most competitive price, we welcome you to buy the heater from our factory.

Immersion electric heating tube product advantage
1. Non-standard custom, flexible production, to meet the heating requirements of various equipment.
2. Corrosive liquid heating immersion electric heating tube can automatically fall off the scale accumulated on the surface of the electric heating tube when heating weak acid, weakly alkaline, or hard water.
3. Flexible threaded thread can be added.
4. Our products have obtained CE certification from the German authoritative certification body - Rheinland Institute and are exported to various countries. [1. Understand the German Rhine Institute 2. View the CE certificate and report].
5. Flow or circulating oil immersed electric heating tube closed oil tank heating flange electric heating tube can be directly fixed on the female ring gear, which is easier to install than the plane flange.
6. Under the same power and length, the flow or circulating oil immersed electric heating tube is lower than the flow or circulating oil flange electric heating tube.
We should pay attention to the following points during the use of immersed electric heating resistance tubular heater element:
1. Its heating zone must be completely immersed in the liquid, and the dry burning phenomenon will burn the immersed electric heating element;
2. The scale of the surface of the immersed electric heating tubular heater should be cleaned regularly to ensure its good service life;
3. The terminal is effectively waterproofed to avoid leakage;
4. The power design of the heating resistance tubular heater per metre of the immersed electric heating pipe shall not exceed 2KW;
Before installing the immersed electric heating resistance tubular heater, make sure that the container is placed in a stable condition before installing and fixing it. Because the container that is not placed smoothly is easy to overturn, dumping the Liquid, causing the immersed electric heating resistance tubular heater to dry, due to fire, electric shock and the like;
6. Do not install the immersed electric heating tubular heater at the air inlet with high humidity. This will easily cause the electric heating tube to be damp and the insulation will drop, which may cause dangers such as electric leakage and electric shock.
