Maltec-H Air Finned Heater

Air Finned heating elements are like basic tubular elements with the addition of continuous spiral fins brazed to the sheath or rectangular fins crimped to the sheath. The finned tubular heater is designed to improve heat transfer to the air and permits putting more power in tighter spaces like forced air ducts, dryers, ovens and load bank resistors. They can be provided with rectangular fins of various thickness. Duct heaters uses fin tubular elements within its design to help reduce the watt density. It also allows for more consistent air flow streams within the duct and increases the life longevity of the elements. 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.

Air Finned Heater use high quality magnesium oxide to allow efficient heat transfer from resistive coil to the heating medium whether it is air, liquid or solid.  These heater elements have a strong outer sheath to help protect against physical stress and uses high quality alloys to allow efficient heat transfer from resistance coil to the heating medium. Depending on their rating, sheath and shape, electric tubular elements are used in a variety of heat applications that require process temperatures of up to 750°C (1 382°F) to heat liquids, gases and solids. A variety of diameters are available to help adjust watt densities in your application to design these electric heaters for best performance and long life. Standard and custom-made terminal pins allow for easy installation and maintenance. Bending radiuses are designed with careful expertise to allow for optimal performance when meeting “form fit and function” within your application.
