Open Coil

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.

Heaters have been produced in configurations up to 50kW.
