Utlising world-leading D+H Mechatronic electric winders manufactured in Germany, the winder units concealed within our 616-series designer awning windows The 24v VCD chain drives are extraordinarily quiet when opening and closing façade windows, making it ideal for daily ventilation operation. These drives can work individually; controlled multiple banks of windows or as dual-units to suit extra-wide sashes. Chain-length is determined by the sash size and can vary from 250mm - 600mm stroke.
Each electric winder is sent power and control signals from a control panel which operates 1 to many motors depending on the desired configuration - the convenience with the D+H control panels which take a direct 240v input and step it down to 24v is the absence of transformers used in other systems which are usually limited to 2 motors and wiring becomes cumbersome.
These ventilation solutions comprise an automated window, rain sensor (optional) and switch on the wall or can be controlled by a central CBUS system or similar smart-home solution. This simple design can be expanded to include a range of internal and external sensors (e.g. Wind and temp) and can be integrated with the mechanical services in such a way that either windows are automatically shut if the building is in heating or cooling mode, or in reverse mechanical heating or cooling is disabled when the occupant selects natural ventilation.
