Crystal Door Systems L.L.C DUBAI

Access to safety-sensitive buildings or areas within a building can be controlled through security revolving doors. Besides functionality, the building architecture is taken into consideration according to the customer's wishes, so a tailor made solution always results. Access controlled in both directions In the initial position, the security revolving door is by means of a motor driven brake system. An access control system releases it. Unauthorized persons are conducted out of the drum in the exit direction.

The automatic all-glass sliding panel system shopMaster GSW-A offers a wide variety of design options for architects and planners as well as maximum convenience for operators or users. The system's compact design requires only minimal space for the roller track and parking niche. The modules are equipped with state-of-the-art carriage technology with plastic-coated, ball bearing-supported rollers. These guarantee permanently reliable operation and noiseless movement of the elements. Thanks to the small roller track installation height of 86.5 mm, installation flush with the ceiling is possible almost everywhere. The required floor guide provides additional stability and utmost convenience to the user. For safety reasons, the automatic all-glass sliding panels can be moved by hand in the event of a power failure.

Chain drives from AUMÜLLER have a slim and attractive, robust aluminium housing, which encloses the microprocessor-controlled electronics, the motor gearbox unit and the chain box. The stainless steel chains are of a basically “rigid-back” design. It caves on in itself in one direction to retract into the housing. In the other direction, the so-called “rigid-back position”, they can be subjected to pressure when extending. The pressure forces depend on the size and shape of the chain links and the stroke length. Chain drives therefore generally have different pulling and pushing forces. Drives with long strokes are used mainly for tensile loads. The integrated microprocessor regulates the drive force by means of a electronic positioning encoder in relation to the stroke length. The soft-start and soft-stop both protect the window drive against overload, and the opening casement as well as the attachment elements against premature wear. The synchronous operation of several window drives are possible, as well as various customer- and object-specific configurations. When installing at the main closing edge, the chain describes a chord to the arch of the sash during the opening process. The casement height therefore depends on the profile geometry, the opening direction and the stroke. Rigid-backed sidebow roller chains are used to open casements of low heights as wide as possible. Chain drives without sidebow chains are swivel-mounted at the brackets. For installation at the side closing edge of bottom-hung windows, the chain drives are mounted to the chain outlet like a drawbridge.

Windows are an integral part of buildings which ensure a pleasant daylight. Due to the demand opening a balanced room climate is achieved with a high proportion of fresh air at the workplace and in the home. To have an comfortable natural ventilation you can use electromotive operated windows. The drives are operated via a ventilation control unit which allows a controlled flow of fresh air. The controlled natural ventilation via window drives ensures high air exchange rates and achieves a very low energy consumption. Sensors record weather and temperature data and other environmental factors via sensor which analyses the data and sends it to the system. Optimum results are achieved when using heating, cooling and sun protection systems. All individual steps of the system are precisely timed and coordinated and are based on individual needs.   Electric window openers for SHEV and natural ventilation AUMÜLLER window drives open and close your windows in a reliable manner. The electrical window drives ensure additional driving rain impermeability and joint impermeability. Combined with appropriate control units and sensors the controlled natural ventilation ensures enough fresh air and pleasant comfort. This system protects the environment and reduces energy costs. The AUMÜLLER product range offers the adequate drive solution for every RWA window: For superimposed leaf- or frame-mounting on the main or secondary closing edge, as well as for invisible integration into the profile. Elegant design, precision processing and convenient functionality enable the optimum integration into modern overall architectural design concepts. Where other equipment reaches its limits, we still provide special solutions: In the stairwell and in the lift, in the office building as well as in airports or classrooms.

The folding wall consists of individual sandwich panels hinged together to give an even appearance when closed. They can either be suspended from, and moved along, an overhead track or can be manoeuvred on an ultra low profile floor track system with a ceiling-mounted guiding track. When closed, these panels give the appearance of a completely even wall. The panels can slide along a floor track system with an ultra-flat profile, guided by a track installed on the ceiling. In this case, the track on the floor bears the full load and no overhead supporting construction is necessary. Alternatively, the panels can be suspended from a ceiling track and moved with floor guidance. The hinged panels are pushed together and will interlock to form a flat wall. The panel construction consists of an aluminium frame, high quality particle boards and contains high-performance sound-absorbent materials. Acoustic integrity is completed by fixed top and bottom sweep seals. The Flexio is available with laboratory acoustic insulation values from Rw 37dB to Rw 44dB. Each wall section incorporates an end pass door panel, which provides a quick method of closing off the wall and also a means of access to adjoining rooms.

Automatic closing is desirable with fire and smoke protection doors. However, a closed door always represents an obstruction. Nevertheless, convenience and accessibility can only be ensured if the door is easy to open. Automatic swing-door drives from the GU Group ensure secure closure yet allow convenient access via the radar motion sensor, push-button or access control system. Entrance doors in the facade can also make use of the benefits of the swing-door drive: when combined with multi-point locking, burglar protection and escape route safety are equally possible as well as ensuring accessibility.
