DBK Open Coil Heating Elements
DBK has developed and manufactured customer specific solutions for open coil air heating applications since 1986. Our customers benefit from this extensive technical and practical know-how. We offer product development support in technically demanding applications for domestic tumble drier heaters and dehumidifiers as well as many other applications.
The mechanical and electrical properties of DBK’s flat wire heating element make it the ideal product for heating air. 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 reduce 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.
DBK has extensive experience manufacturing heaters with output configurations of up to 50kW. Please contact us with inquiries regarding open coil projects.
