What Is a Tubular Heater Used For?
Tubular heater applications include industrial ovens, air heating systems, drying equipment, tanks, liquid heating, molds, packaging machinery, and other industrial process equipment. Tubular heating elements can be customized in different shapes, sizes, materials, voltages, and wattages to match specific heating requirements.
Tubular Heater Applications
Tubular heaters are commonly used when reliable and controlled electric heating is required.
- Industrial ovens: Provide controlled heat for heating, curing, and processing.
- Air heating: Heat air and gases in ducts, chambers, dryers, and ventilation systems.
- Liquid heating: Heat water, oil, and other industrial liquids with suitable heater designs.
- Drying equipment: Generate hot air for industrial drying processes.
- Tanks and vessels: Maintain or increase the temperature of process liquids.
- Molds and machinery: Provide localized or distributed heating.
- Packaging equipment: Supply controlled heat for sealing, forming, and processing.
The required heater design depends on the heating medium, temperature, installation space, power requirements, and operating environment.
How Does a Tubular Heater Work?
A tubular heater converts electrical energy into heat through an internal resistance wire. Magnesium oxide insulation surrounds the resistance wire, while a metal sheath protects the element and transfers heat to the application.
- Electrical power enters the heater.
- The resistance wire generates heat.
- Heat passes through the insulation.
- The metal sheath transfers heat to the surrounding medium.

Which Tubular Heater Is Right for Your Application?
Straight Tubular Heater
A straight tubular heater provides a simple linear heating configuration and is suitable where installation space allows a straight heating element.

U-Shaped Tubular Heater
A U-shaped design provides a longer heating path in a compact installation area. It is useful for equipment that requires more heating length without using excessive installation space.

Finned Tubular Heater
Finned tubular heaters use metal fins to increase surface area and improve heat transfer to air and gases. They are commonly used in air heating and drying systems.

How to Choose a Tubular Heater
The correct heater should be selected according to the actual application rather than heater shape alone.
- Heating medium
- Required temperature
- Voltage and wattage
- Watt density
- Tube diameter and heated length
- Sheath material
- Installation space
- Terminal configuration
For a step-by-step selection process, see our tubular heater selection guide.
Can Tubular Heaters Be Customized?
Yes. Tubular heating elements can be customized for different industrial equipment and installation requirements.
Customization can include tube diameter, heated length, overall dimensions, shape, voltage, wattage, sheath material, terminal position, and lead configuration.
This makes tubular heaters suitable for both standard equipment and OEM heating applications.
What Information Should You Provide?
When requesting a tubular heater, providing the following information can help us recommend the right design:
- Application and heating medium
- Required temperature
- Voltage and wattage
- Heater dimensions
- Tube diameter
- Sheath material
- Shape and terminal requirements
If you have an existing heater, drawing, sample, or equipment specification, you can also provide it for evaluation.
