  • D+H chain drive CDM-5-BSY+

CDM series: enormous power at a HIGH STROKE

Strong smoke vent and ventilation drive for heavy roof or
façade windows

The CDM series chain drive effortlessly moves heavy roof and façade windows with a push and pull force of 1000 N. Thanks to the clever triple deflection of the chain, its short design makes it the most compact drive in its class. Equipped with Modbus-based ACB technology, it can be flexibly configured according to project requirements using the D+H SCS software. With its central chain outlet and plug-in cable connection, the drive is easy to install. The universal bracket also enables uncomplicated installation on a wide range of window profiles. Its particularly robust and rigid steel chain and brushless motor make this drive particularly durable and virtually maintenance-free.

  • High force from 1000 N at up to 1000 mm stroke 

  • Compact design thanks to clever triple deflection of the chain

  • Robust chain and durable, low-maintenance motor

  • Acoustic decoupling: virtually silent opening and closing of windows

ACB technology

The CDM 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.
