High insulating capacity and roll speed can save energy. Door System has developed the DS800 especially for use in freezer rooms, including the specially designed door curtain and the special sealing system.

We manufacture all our products at our own factory in East Jutland, complying with all applicable requirements and standards. DS800 is available in sizes up to 4.0 x 3.3 m, however not exceeding a total area of 12 m². If you need a bigger door, choose instead the upgraded model, DS 850, which is available in sizes up to a full 4 x 5 m.

High insulating capacity

DS800 was designed for use in freezer rooms and features a door cloth specially developed not to let the cold escape. The door cloth on DS800 is no less than 43 mm thick and has special built-in stabilising features to ensure a highly efficient insulating capacity. At the same time, the cloth offers good resistance to wind loads. DS800 is equipped with a special sealing system which ensures that cold and hot air do not meet and form condensation and ice.

Save energy

Your budget will benefit if you install a DS800 insulated door with high insulating capacity and high roll speed. 75,000 kWh: These were the total savings which we calculated for one of our customers, Claus Sørensen A/S, who wanted to replace their roller door to the freezer room with a DS800. Three years later, the Danish Technological Institute’s analyses showed that the actual savings are close to 90,000 kWh.
