CDC series: integration in perfection
Incredibly quiet and virtually invisible
You'll probably miss it, unless you look closely and listen very carefully: The universal CDC chain drive for installation can be integrated into the profile or surface-mounted and is so compact that it is virtually hidden once installed. Ingenious mechanical decoupling means the chain drive runs extremely quietly. This makes the CDC ideal for visually refined and functionally adept façade solutions for smoke extraction and natural ventilation. The CDC provides pure convenience and optimum flexibility. It is suitable for multiple window and façade solutions and for all standard window profiles. Thanks to its intelligent powerful motor electronics, the CDC can be programmed individually using the D+H SCS software. Configure the drive functions, performance features, stroke lengths, opening widths and speeds for opening and closing separately entirely according to your requirements and applications. This makes the drive a secure and customised solution that complies with the highest standards of architects, specialist planners and fabricators, all while being incredibly quiet and virtually invisible.

Versatile installation solutions for a range of window profiles
The CDC is the most flexible solution for all façade windows in cases where ventilation and smoke extraction drives are to be out of sight. Thanks to the profile-related bracket sets consisting of a frame bracket and sash bracket, the CDC is fast and easy to install in nearly every window – without additional work to adjust the fitting. It is inconspicuously concealed in the window profile, where it functions entirely unseen, moving bottom-hung, side-hung and parallel projecting windows. For natural ventilation with the highest standards for design and function. And if need be, the sleek CDC can also easily be surface-mounted.
In combination with the professional SHEV and ventilation drive of the CDC series featuring an 800 mm stroke, this D+H solution provides sideways window opening without a chain detracting from the view. A pneumatic spring ensures safe operation for inward- or outward-opening side-hung vents.
The CDC series at work: the Glucksman Library
The Glucksman Library at the University of Limerick is one of the largest campus libraries in Ireland, and one of the most digitally advanced in the world. In 2018, the existing building was extended by 7,600 square metres, and was also radically redesigned to provide quiet traditional reading and learning areas to livelier, technology-driven group and community spaces.
The project consists of 246 CDC-1-ACB 24V chain drives that are operated directly by the building management system via Modbus. The building management system is able to control each window with perfect positioning, either individually or in groups, using the ACB technology.
The opening and closing speeds of the drives can also be regulated separately. Thanks to their scarcely audible operating noise, D+H drives ensure a comfortable learning environment and an optimal indoor climate at all times.
