W Shape Industrial Tubular Air Heater Electric Finned Heater
Finned strip heaters are an electric heating element that maximizes heat intensity and transfer effectively in an area. Steel fin strip heaters are an excellent industrial heating product that can be installed on the surface of the heater. Mounting holes are useful to mount the heaters securely on the wall housing with terminal extending from the sheath for easy electrical connections.
Finned strip heaters are composed of a heating element, a protective sleeve or sheath, and mounting hardware along with steel finned that are used to extend surface area. If strip heaters are used as a radiant heater, or a duct heater, they have can have fins to maximize surface area and heat transfer to the air. Strip heaters can be clamped or bolted onto objects or solid surface contact heating over large areas and are primarily used in indoor applications.
1.Tube diameter: Φ2mm-Φ30mm
2.Tube Material: Fe, SS304;SS316,SS321,ss202 etc
3. Insulation Material:High-purity Mgo
4. Reisistance wire element:Ni-Cr or FeCr
5. Lead Connection Option: Crimped or Swaged leads
6.Lead and type of connection leads, 10″ Fiberglass Standard(Wire options,silicone high temperature frberglass).
7. The voltage and power can customized
8. The shape of tubular heater can be customized according to your drawing
In applications where tubular heaters are exposed to forced convection, placing fins around tubular heaters increases their surface area and thus improves their heat transferring capacity. Finned tubular heaters, compared to regular tubular heaters, run at lower surface temperatures for the same watt densities when placed in identical air streams.
