The D+H CDC-0252 chain drive – remarkably quiet and virtually invisible

Technical innovations that are there to serve the plans of the architects, fabricators and users: This D+H philosophy is also behind the CDC-0252, which can be integrated almost invisibly into virtually any façade concept thanks to the innovative decoupling in the drive technology. This decoupling works in a remarkably quiet manner and overcomes even the most difficult sashes quickly and safely.

The CDC Series has always owed its success among planners and window manufacturers to its enormously wide range of applications: The sleek and powerful chain drive for installation integrated into the profile or mounted installation can be used with wooden, aluminium and plastic profiles. There are no unsightly external fasteners. Once this multi-talented solution is installed in the window, you will notice its function as it quickly and unobtrusively ensures natural ventilation and smoke extraction. And the heat transfer coefficient? Testing by ift Rosenheim showed that it only saw a minimal increase with integrated installation.

Due to the fact that noise emissions were lowered by 6.8dB, and thus a factor of 5, the CDC-0252 is also setting benchmarks in terms of comfort for the building users thanks to the innovative decoupling in the drive technology. This was made possible due to a simple yet effective solution: Where metal meets metal, things get loud. Thanks to the innovative decoupling of the drive technology and additional design measures, D+H managed to achieve a quiet revolution with the development of the CDC-0252. In addition, experiments were carried out on various motor flanges and the brackets were also decoupled. The results of this process are just as stable as before but significantly quieter. Detailed tests run by the acoustics specialists at Novicos were able to demonstrate, among other things, by comparing three variants of drives with one another. Considering that the human ear perceives a difference of 10db as twice as loud, it is clear that even small improvements can mean tremendous progress.

The programming of the CDC is strictly user-oriented and therefore particularly easy and reliable: Thanks to the intelligent and powerful motor electronics, the chain drives can be programmed individually via PC and Windows tablets using D+H SCS software. As a result, the drive functions, performance features, stroke lengths, opening widths and speeds for opening and closing can be set separately according to the application. A stroke of 350, 600 and now a NEW stroke of 800 mm in 60 seconds via the high-speed function with a comprehensive and tensile force of 250N is possible depending on the version. Intermediate sizes and longer strokes are also possible upon request. The CDC can be integrated perfectly into building automation thanks to the innovative new ACB bus communication based on the Modbus: This technology enables position-accurate control as well as the creation of virtual groups. This makes the CDC-0252 a particularly reliable, flexible solution and individually customisable drive solution for SHEV and natural ventilation.

CPS SERIES
Ingeniously Simple - Ultra-Compact

• Integrated ACB technology creates new communication between drive and control panel
• Nothing is easier than installing and retrofitting with the wireless rail-mounted plug-&-play system
• User-friendly operating concept thanks to the large colour touch display

A new time calculation begins after about 17,000 development hours

Since September 2015, 15 D+H developers have worked on the new digital smoke vent control panel on a daily basis. The result is setting standards in the areas of cost-effectiveness and networking. This has initiated a new era for system solutions in the field of smoke and heat exhaust ventilation. Thanks to the compact, uniform design of the individual modules, powerful control panels can be integrated into small control cabinets. The fully modular design can be expanded at will.

The virtually wireless, rail-mounted connector system is easy to install and expand. Just one click expands the system by one module, introducing many new functions. This principle has the advantage of ensuring significantly less wiring and an improved power supply. The control panel provides a nearly unlimited output current in 20 A increments. Moreover, the CPS-M can be integrated into the building automation infrastructure. Thus, it can work together with the heating, ventilation, burglar alarm or fire alarm Systems.

Smart and innovative: communication and Controller

D+H is introducing a new, user-oriented innovation to the market with the Advanced Communication Bus (ACB). It enables bidirectional communication between the control panel and drive. This means that the control panel also receives information about the position and condition of the windows. It also enables triggering of the drives with perfect positioning. Yet another advantage of CPS-M: Functions and dependencies can be integrated into the controller quite easily using the SCS software. This may be a switch-on module for sun shades or a fire detection module.

AdComNet (Advanced Communication Network) is the internal bus communication system that CPS-M uses. It combines communication data into a single, comprehensive system and enables communication between additional CPS-M control panels or controllers of the RZN-M Series. A special highlight is the autonomous communication of the system. In addition, having VdS approval makes AdComNet the only certified SHEV bus system on the market. In short, with the intelligent CPS-M you have a flexible and costeffective system solution that already fulfils all requirements concerning norm prEN 12101-9. In future, you will see that only one thing in your building will take your breath away: our Innovation.
