ZA series: the reliable expert for roofs

Rack and pinion drive for reliable performance at height

At dizzying heights ZA Series drives radiate absolute superiority: they open windows and skylights in the roof area fully automatically, efficiently and safely. Equipped with robust racks and pinions, they have a high pressure resistance, which enables them to open even heavy sashes without any difficulty. Whether for the life-saving smoke vent in case of fire or for everyday natural ventilation: The toxic gases escape quickly through the wide openings – the drives make stroke lengths up to 1,200 mm possible – and fresh air flows into the buildings. External conditions do not affect these drives. Optionally integrated heating resistors ensure that the electronics work even under severely fluctuating climatic conditions.

The ZA series at work: California Academy of Sciences

The California Academy of Sciences in San Francisco is a very special museum of natural history. For the structure and external shell of the building, the architecture firm of Renzo Piano made use of knowledge of bionics, in other words principles of building physics that are derived from biology.

The challenge for D+H in this project was to provide the entire air conditioning and ventilation technology for this large-scale building complex. Forty rack and pinion drives were installed in the numerous skylights as well as multiple chain drives in the windowed façades.

The drives are connected to the central building control system and thus react to all climate data. The windows open and close accordingly to provide natural ventilation. The entire building complex provides all visitors with an feel-good atmosphere.

ACB technology

The ZA 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.
