Finned tubular heater

Short Description:

Finned heaters are constructed using WNH robust tubular element as the basis of construction. Fin material is continuously spiral wound tightly onto the element surface to increase the convective surface area for air and non-corrosive gas heating. Fin spacing and size have been tested and selected to optimize performance. Steel finned units are then furnace brazed, bonding the fins to the sheath to increase conductive efficiency. This allows higher wattage levels to be achieved in the same flow area and produces lower sheath temperatures prolonging heater life. For higher temperature or more corrosive applications, stainless steel fins securely wound on alloy sheath are available. Application conditions such as vibration and toxic/flammable media should be taken into consideration when installing heaters. Protective coatings are available for use on steel finned heaters for mildly corrosive or high humidity applications.

3.How Do Tubular Heating Elements Work?

Tubular heating elements transfer heat through direct exposure to a liquid, solid, or gas. They are configured to a specific watt density, size, shapes, and sheath based on their specific application. They can reach temperatures of 750 degrees centigrade or higher when configured properly.

4.What Mediums Can Tubular Heating Elements Be Used For?
Tubular heating elements can be used for heating a variety of mediums including liquids, gases, and solids. Tubular heating elements in conduction heaters use direct contact for heating solids. In convection heating, elements transfer heat between a surface and a gas or liquid.
