Contact surface heaters are fitted throughout the entire EFAFLEX high-speed door, integrated into the seals around the opening and into the bottom beam. These heat the contact surfaces of the seals where they meet the door blade and floor. In comparison with other door solutions you can save up to 50% on heating costs by using an EFAFLEX deep-freeze high-speed door. The result of this unique design is heat transfer coefficients of as low as 0.62W/m2K in operational temperatures between plus 30°C and minus 30°C.
