ASB Heating Elements Limited offers you the absolute best Tubular Heating Elements available.

Experts In Element Design

With many years of experience designing and applying heating elements, we have mastered both the science and art of Tubular Heating Elements manufacturing. Your ASB heater will perform as you expect it to.


ASB uses 80-20 ni-chrome wire, "A" grade magnesium oxide, and the highest quality tubing. Filling machines and roll reduction equipment are expertly maintained to manufacturer's tolerances, and final test equipment is fully calibrated. You can expect high quality from us.

Tubular Heating Elements have 4 basic components:

1. Metal Sheath
2. Magnesium oxide (MgO)
3. Helix resistance coil
4. Cold section at each end

Here Is What Makes The ASB Tubular Heating Elements Your Obvious Choice!

1. A variety of sheath materials are available for different application conditions. These take into account corrosion and temperature factors. Let us help[ you choose the optimum sheath material to ensure the longest possible life for your application. Sheath materials include:

a. Steel
b. Copper
c. Titanium
d. Incoloy 800®
e. Incoloy 840®
f. Inconel 600®
g. 304 stainless steel
h. 316 stainless steel

2. Only grade "A", High Purity, MgO is used in all ASB heaters. This material contributes to better heat transfer properties and higher electrical insulation from the sheath. The result is a high quality heater which meets the rigorous demands of Industrial process applications.

3. The resistance element in all heaters made by ASB is a premium grade 80/20 Nickel-Chromium Alloy. this material offers higher temperature capabilities and mechanical strength. As with the MgO insulation, a superiror heater component leads to a superior element.

4. The heater element requires a cold section at each end to keep the electrical terminals from overheating. A steel pin of the desired length is used for this purpose. It is spot welded to the helix coil element for a secure connection. In the final step of assembly, the pin is exposed at each end of the element and is ready to accept a variety of terminal options.
