The customer that chooses KRISPOL does not have to struggle with opening or closing the grille.
Everything is done without any problem or effort. Proven engines are mounted in the grilles, the power and structure of which are adjusted to the size and weight.
Small-sized grilles may also be opened manually.
The customer may choose from several options for controlling the automatic grilles. They may be opened by means of a control station, transmitter (two- or four channel), code keypad, key button or key switch. It is possible to use group control that allows for simultaneous opening and closing several grilles or other elements of the building elements, e.g. rolling shutters, regardless of the number of channels.
