Simple automatic possibilities for ventilation
We have recently finished a very sophisticated new project in aluminium in central London consisting of doors and windows with inwards openings. It features windows that open electronically.
We used high performance chain drive from GEZE – ECchain that gives us ventilation at 230 V suitable for private residential buildings.
The integrated stroke setting option allows for adjustment in line with different ventilation requirements. The stroke length can be set to 200 mm or 400 mm. Appropriate for bottom-hung, side & top-hung casements. The ECchain can also be used as a variant on small fanlights, since a maximum opening angle is reached with very low casement heights.
