●Heating costs lower than normal curtain about 15%.

●You can easily adjust the opening in accordance with instructions issued by the controller.

Tunnel ventilation mode

●In tunnel ventilation mode,adjust the air intake volume to gain suitable longitudinal ventilation speed and decrease the dead zones.

●Doors made of insulation material,to reduce heat loss when outside temperature is much lower than inside. 

●Tunnel doors frame sealed with auto industry door sealing technology ,which can prevent wind entering and avoid stress reaction of birds.
