Polystyrene is self-extinguishing. EPS Sandwich Panel has excellences of light weight(1/20-1/30 of concrete), heat insulation, rapid construction speed(operate withouthumidity and needn't repeated fitment). It is a new type protection structural material, congregates bearing, heat preservation and water resistance.
The operator memorizes the limit positions and unique braking system that slows the unit down at the end of its travel. Soft start and soft stop control guarantees extremely smooth and quiet operation.
soft start and soft stopsafety obstacle reverse, during closing, when the door meet obstacles, the door will open automatically self-learning opening force, and self learning closing force self-closing feature Low-voltage protection, the opener will not perform any action of opening or closing when voltage is too low,
in this case, door panel and controller won’t be damaged
Can be with infrared sensor for protection Can be with battery backup, in case of power failure Can be with wall switch Can be with flash light Can be with pass door protection Can be with O/S/C button
