220V 3kw 5kw Electric Resistance Air Tubular Finned Heating Element for Oven

Product Description

High Efficiency Air Finned Heater

Finned Tubular Heaters are designed by winding metal radiating fins around U-shaped tubes, which accelerate heat dissipation by expanding the heat dissipation area. They are widely applicable to air heating scenarios such as ovens, paint baking rooms, and load cabinets.

 

Our range of finned tubular heaters are suitable for increased heat transfer surface area and where higher wattage is required.Featuring rugged construction, these finned heaters can be used in a multitude of industrial environments.Finned tubular heaters are used for forced convection heating, air or gas heating systems.They are customized to meet your specific application needs.

How to choose?

1.  Dimensions
For in-equipment installation: Select suitable threads (M16/M18/M22, etc.), and ensure the tube length fits the equipment's accommodation space.
For flat installation in open environments: Thread specifications are optional;  only length compliance is required.

2.  Power & Voltage
Replacement scenarios: Refer to the power and voltage parameters of the original heating element.
New installations: Contact us for professional calculation or arrange a technical consultation.

3.  Material Selection
Determine the heating tube material based on the ambient temperature.
Note: If the required finned heating tube specifications are out of stock, customized orders are available.

4. Other special requirements if you have.
