Description

The DBK flat wire heating element is ideally suited for heating air due to its mechanical and electrical properties. The large surface of the flat wire spiral and the low air resistance ensure excellent convective and radiant heat transfer.


The patented process of winding the wire onto an electrically insulated winding strip provides a stable and secure open coil. The unique construction of the spiral ensures greater reliability and safety.



The low watt density and lack of air shadows reduces hot spot temperature. The streamlined nature of the spiral reduces fluff/lint collection, making the element safer for tumble drier applications. The Mica in the center of the spirals supports the wire along its length, thus reducing the likelihood of short circuits if the wire is damaged in any way.


Heaters have been produced in configurations up to 50kW.
