Tubular heater construction
Tubular heaters consist of resistance wire, compacted MgO insulation and a metal sheath. This structure provides both electrical insulation and efficient heat transfer.
Forming options
Straight, U, M, serpentine or project-specific formed shapes can be produced. The form is selected according to mounting area and heated surface geometry.
- Straight tubular heaters
- U or M shaped heaters
- Finned air heaters
- Custom OEM heaters
Applications
Duct heating, machine surface heating, mold heating, liquid tanks, air systems and process equipment are common tubular heater applications.
Selection criteria
Sheath material, watt density, operating temperature, ambient conditions, mounting style and electrical termination must be evaluated together.
Frequently Asked Questions
Can tubular heaters be custom bent?
Yes. Special forms can be produced according to mounting space and process requirements.
What is a finned tubular heater used for?
It increases heat transfer area on the air side and improves performance in duct and air flow applications.
