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.
