Correctly setting door closers

… strong>strong</strong>, the door will close with a slam. If the regulation is too weak, on the other hand, the door may not be able to close fully on its own. The back check is a shock absorber that prevents a door from being opened too forcefully. Persons, door elements, adjacent walls or objects behind the door are protected. So the back check reduces the speed of a door that has been opened forcefully. However, for instance in doors that open outward and may be exposed to the wind, it must not be used as a substitute for separate measures designed to limit the opening angle - such as installing a door stopper or other structural methods. Note: the valve should not be opened too far, since this can cause leaks. The delayed closing reduces the closing speed of a door. This gives persons with luggage, walking aids, and other restrictions enough time to pass through the door.

Best air quality through indoor climate control

… strong>strong</strong> ventilation is avoided. Tolerance for user intervention: users have the possibility to change e.g. temperature, light and ventilation. The system will subsequently ensure that everything is restored to its original state if the user forgets. GEZE ventilation and indoor climate control The GEZE indoor climate control system for controlled natural and energy-saving ventilation complements the GEZE window drive and RWA programme. The RWA systems can also be extended by sensors and control elements and can be integrated into building management systems. Via the IQ box KNX interface module, GEZE enables the simple integration of automated window drives in KNX environments – for intelligent interaction of window drives and sensors. Other KNX-capable systems and drives or building technology components, such as solar protection systems, heating controls or air conditioning, can also be linked to the GEZE indoor climate control. GEZE offers numerous possibilities for the automation of indoor climate components. Our fully automatic control is project-specific, extremely flexible and easy to expand. Sven Kuntschmann, window technology segment manager With the IO 420 interface module, all GEZE system components become ‘networkers’. Automatic door systems, ventilation technology and smoke and heat extraction systems (RWA) as well as safety systems can be integrated into the higher-ranking building management system via BACnet in order to automate their functions. GEZE thus makes a contribution to the Smart Building through intelligent building networking. Since the demands on indoor climate control and sophisticated ventilation controls are very different, these solutions are individually planned depending on the building project. The GEZE Customer Solution Team is happy to help with concept and planning. The GEZE range of services and products for indoor climate control Drive systems for aeration and ventilation Ventilation solutions: simple open/closed control of individual windows or groups of windows through to comprehensive central controls Comfort solutions for automatic ventilation depending on weather, temperature and air quality Simple radio-based solutions for individual rooms up to comfortable room/building control systems controllable via a modern touch display Intelligent RWA control units also enable ventilation functions Go to the GEZE IQ box KNX interface module Go to the GEZE MBZ 300 N24 emergency power control unit Go to the GEZE Slimchain universal chain drive System example: gymnasium with RWA and indoor climate control Diagram of indoor climate control in a sports hall © Elsner Elektronik GmbH / GEZE GmbH A building with various rooms serves as an example: gymnasium, entrance area, technology room, locker rooms and shower rooms. Benefits of the RWA / indoor climate control combination Indoor climate control Optimum indoor climate in the sports hall for the hall users, since ’fresh’ air is supplied depending on the air quality (mist), humidity (sweat) and temperature. Manual intervention is possible if the automatic functions do not meet the needs. In rain and <strong>strong</strong> winds, a rain/wind sensor on the roof closes all the windows automatically, thus protecting the building stock. Automated ventilation offers comfort for users, prevents mould and its effects on health, and avoids premature renovation being required. The automatic closing of the windows outside operating hours protects against burglary and needs no additional intervention by the caretaker. The smoke and heat extraction (RWA) guarantees personal protection (keeps escape routes free from smoke) environmental protection (reduction of environmental damage by minimising the use of extinguishing agents) protection of property (maintains the building structure by minimising thermal loads and ventilation of the fire) Gymnasium Motorised fanlight windows opening outward are integrated into the gymnasium façade. During normal operation, the hall is automatically ventilated via the fanlight windows depending on the indoor and outdoor temperature, humidity and air quality (CO2). The fanlight windows can also be opened or closed manually in separate groups via vent switches. The façade is equipped with blinds for shading, which automatically extend depending on the brightness and position of the sun, but do not collide with the fanlights. Motor-driven roof windows are installed in the gymnasium’s roof of the hall, which open when smoke develops and conduct the smoke out of the hall (RWA ) . An uninterruptible power supply (UPS) ensures that 230 V devices (blinds) are safely opened in the event of a fire (RWA). The building entrance door, the connecting door to the corridor and the door to the gymnasium serve as an exhaust air opening (RWA ) . Entrance area There are motor-driven façade windows in the entrance area. Windows are operated manually via push buttons and close automatically at the latest outside the operating hours. Technology room There is a motor-driven façade window in the technology room. The window is operated manually via a push button and closes automatically after a preset time (e.g. 30 minutes). Shower rooms There are two motor-driven fanlights in each shower room. Fanlights are controlled as a function of humidity and indoor and outdoor temperature. Windows can also be operated manually via push buttons. Mould infestation can be avoided. Locker rooms There are two motor-driven fanlights in each of the locker rooms. Fanlights are controlled according to air quality, humidity and indoor and outdoor temperature. Windows can also be operated manually via push buttons. Product video GEZE Powerchain chain drive for automatic room ventilation Planning Installation Services Planning Installation Services Sophisticated solutions from a single source GEZE indoor climate controls are customer-specific applications consisting of combined RWA and ventilation systems. With Customer Solutions from GEZE, you benefit from sophisticated, individual solutions that offer the best possible safety and convenience. And all this from a single source. Your contact person will answer all your questions, from the initial idea right up to the commissioning. Natural automatic ventilation has a very high acceptance among end users, especially if they can intervene manually (e.g. by local ventilation buttons). A ventilation concept based on natural ventilation minimises or avoids the planning of ventilation shafts in the building. Compared to mechanical ventilation, no additional ventilation openings are necessary in the façade and thus do not influence the architectural design of the façade. low-noise operation (no fan noises) lower investment, installation and maintenance costs than mechanical ventilation systems Consultation-friendly, reliable planning, scalable: with the compact drive control modules, various ventilation concepts (individual, group, central controls) can be easily planned and scaled. Installation, commissioning and operation made easy We offer simple assembly and commissioning, e.g. by circuit diagram and description on individual drive controls. This reduces sources of error and ensures speedy connection. The scalability of the control allows maximum flexibility and the spare parts can be stored in the service vehicle as only a few control types are in use. Comfort and freedom GEZE is your partner at every stage of your planning. From the first consultation, through to installation and after-sales service. Thanks to our industry know-how, we are able to recommend individual property solutions quickly, as the approaches here are usually very similar.

Sliding door systems for the i360 viewing tower – GEZE

… strong>strong</strong> winds, meaning that sliding doors were more favourable than a swing door solution. At the same time, the sliding door system had to withstand the raw elements of the coast as well as the high influx of visitors. The six side-by-side sliding doors with GEZE Slimdrive SL NT sliding door drives are an ideal solution with regards to function and design. The British Airways i360 is a vertical pier; just like people in Victorian times, who enjoyed the 'walk on the water' on the West Pier, the visitors of today are fascinated by the 'walk through the air' with the i360. The right doors were an essential part of the project - quiet and efficient, durable and above all, visually in line with the glass aesthetic of the Beach Building. David Marks, chairman of British Airways i360 and managing director of Marks Barfield Architects State-of-the-art architecture with maritime history The British Airways i360 stands directly in front of the beach, at the exact height of the former West Pier . As a homage to the pier that was burned down in 2003, the two original payment offices of the West Pier were reproduced at a great cost. To the left and right of the viewing tower, set at each end of the accessible roof of the Beach Building, the historic ticket offices serve as a ticket centre and a café, and reflect the maritime heritage of the i360. The viewing gondola, with its all-round glazing, also offers a view back into the past. With up to 200 passengers, the cabin travels 138 m up the steel column of the viewing tower, and provides a view of Brighton, Hove and the English Channel, as well as the remains of the once magnificent West Pier , which still look out over the sea. We are extremely delighted that GEZE products are being used in a project as representative as the British Airways i360. The viewing tower is a unique structure which uses materials and technology from all over the world. With certainty, the i360 has become a new landmark for the UK, and we are proud that our sliding door systems are there to guide millions of people to this fantastic experience.
