Contact surface heaters are employed throughout the entire door, being integrated into the seals around it and into the contact bar strip. These heat the contact surfaces of the seals against the door blade and the floor. The result of this unique design is a U value down to 0.74 W/m²K and operational temperatures between plus and minus 30 °C.
