VCD series: professional ventilation, universal design

Chain drive for natural ventilation

Tried-and-tested D+H technology for natural ventilation with technical and functional refinement. The chain drives of the VCD Series are suitable for almost all façade and roof windows. Thanks to optimised brackets, they can be installed quickly and used universally. The window drives are equipped with the Advanced Communication Bus (ACB), which is based on Modbus RTU. This allows the drives to be integrated directly into the building management system and controlled with millimetre precision. Do you want your windows to open to just a tiny gap of 50 mm in the summer? Or would you rather have 300 mm for powerful purge ventilation? 
Thanks to its slim construction using solid die-cast zinc, the VCD Series features minimal dimensions with high functionality and performance power. The high-performance chain drives made of hardened and galvanised steel offer 200 N of force of pressure and tensile force. If needed, the opening stroke can be steplessly configured for the TMS+ variant using a magnet. The ACB drives, on the other hand, can be configured quickly and easily using the D+H SCS software tool.

  • Sophisticated and elegant solution for automated opening of bottom-hung windows, top-hung windows, side-hung vents and roof windows

  • Precise control using D+H original ACB bus technology

  • Low operating noise of max. 46 dB(A)

ACB technology

The VCD drive series features the D+H communication technology ACB. Especially during major projects, building operators are often faced with the question, "Do all the installed system components also work for smoke extraction and natural ventilation? And if not, where in the network does the problem lie?" ACB allows the drives to communicate with the controllers and gives them feedback about opening widths and statuses. But this is just one major advantage of the innovative bus technology. It also significantly reduces wiring effort, which in turn saves installation effort and costs, and makes it possible to control drives with millimetre precision.
