All About Tubular Heaters

In process heating, tubular heaters fall in the category of electric heaters usually having high surface temperature within a preheated segment of a machine. They use infrared radiation along with air flow for transferring heat to a liquid or gaseous medium. Not just this, but these are also used in a variety of applications; one of which being used for the greenhouse process to provide heat to the plants, in closed room or synthetic gardens, and within birds and animal cages.

Heating Elements

Heating elements of tubular products are factory configured and are properly tested prior to their launch in market. These are available in many different sizes and shapes, designed according to the heating devices they are to be applied for. Elements used during manufacturing of these heaters are similar to that of others namely titanium, incoloy, inconel, steel and stainless steel. The exterior sheath material is made with robust technology and sturdier alloy so as to withstand physical strain and for protection against heat.


Technical Insight

The watt density, size, shape and sheath of each tubular heater and its related elements vary as per their application. These are used during the industrial process of conduction, convection and radiation in which the temperature surpasses beyond 750 degree centigrade to heat several solids, liquids and gases.

Terminal pins are made under industrial regulations; however, they can vary upon request for easy installation and overall maintenance of the device. For best performance and output, superior quality magnesium oxide is used to transfer heat in an efficient way via coil, directly to the source.

Additional technical details are provided below;

–          Manufacturing of cold sections can also be made upon request

–          Maximum flexibility for better performance and watt density range can be as high as 120 WPSI but only on request

–          Thick and sturdier sheath material is also available for rigorous applications



Common Applications

Provided below is a table which highlights in detail about the application of each tubular heating device according to the sheath material used during manufacturing.

Sheath Material Applications
Copper Tubular heaters having copper based sheath material are ideal to be used in water, oil and grease to provide the right amount of heat as well as to for a stabilized viscosity.
Steel For stronger applications like in tars, air heating solution, asphalt and alkaline cleaning fluids, steel made sheath material is utilized.
Stainless Steel Stainless steel is applied to such mediums that are corrosive and may develop a layer of sludge or rust if not properly treated. Acidic fluids, food processing and radiant heating solutions are commonly heated with stainless steel covering.
Incoloy Being anti-corrosive and sturdier, Incoloy made heating device is exposed to many caustic fluids and in cleaning/degreasing liquids.
Inconel This is applied in plating and picking solution along with acidic medium.
Titanium The stronger sheath material is made of titanium flange which is durable and prone to deterioration. Common applications include almost all types of acidic and harmful liquids.







Check out below for all the benefits you can get out of tubular heaters and its use.

–          Advance controlling mechanism for precise heat transfer and temperature maintenance

–          Compact size that makes it easy to install, clean, maintain and even replace in case of damage without seizing the production period for a longer term

–          Available in different shapes and sizes with each category specifically designed with robust technology for longer durability of the product
