Smoke Extraction and Ventilation

Smoke Ventilation systems
This system protects human lives. The quicker the smoke is expelled, the quicker the people trapped in the building can escape, and the better the rescue forces' chances will be. AUMÜLLER ferralux® provides security in staircases and elevator shafts, office buildings, airports, and classrooms with effective control units, drives, and smoke and natural ventilation systems (NSHEV). Smoke ventilation plays a significant role in providing a safe route for escape and mitigating dangers during emergencies.
2. Electric window openers for SHEV and natural ventilation
Window drives, which, in case of fire, effectively open SHEV windows, save lives. And without a fire, they provide proper day-to-day ventilation, yielding agreeable comfort thanks to controlled natural ventilation. This is for the protection of the environment as well as lower energy costs. The AUMÜLLER product family has the proper drive solution for all SHEV windows: For mounting on the top or side closing edge of casement or frame profiles, as well as for integration into the profile. Elegant design, accurate processing, and handy functionality make the best possible integration into contemporary overall architectural design ideas possible. Where others meet their limits, we still offer special solutions, such as smoke and natural ventilation systems suppliers in Dubai.
Chain Drive
AUMÜLLER chain drives have a slender and elegant, solid housing, which houses the microprocessor-controlled electronics, the aluminium motor gearbox unit, and the chain box. The stainless steel chains are of a fundamentally "rigid-back" type. It folds inward upon itself in one direction to be able to retract into the housing. In the opposite direction, the so-called "rigid-back position," they may be exposed to pressure upon extension.
The forces of pressure vary with the chain link size and shape as well as stroke length. Chain drives thus tend to have dissimilar pulling and pushing forces. Long-stroke drives are employed primarily for tensile loads. The built-in microprocessor controls the drive force through an electronic positioning encoder relative to the stroke length. The soft-start and soft-stop both safeguard the window drive against overload, and the opening casement and attachment elements against premature wear. Multiwindow drives can operate synchronously and various customer- and object-dependent configurations are also possible. The smoke ventilation and natural airflow management are improved.

Spindle Drive
The AUMÜLLER spindle drives have slim, round or rectangular continuous aluminium housings and end caps of aluminium or plastic. The housing length is established by type-dependent fixed basic construction length that, in its turn, is predetermined by the microprocessor electronic control and by the motor-gear unit as well as the stroke-dependent, variable length of the spindle housing. The spindles made with ball bearings and end position damping are provided from high-class stainless steel or phosphated steel. The mechanisms for opening have spindle tubes prepared of stainless steel or anodized aluminium. Spindle tubes are supplied as standard with fixed or exchangeable eyebolts for swivelling mounting to different casement brackets. The spindle drives can be mounted either through adjustable clamping rings or sliding components on the housing tube, eye-bolts, or clevis brackets in the housing bottom rear. The easy-to-use, adjustable fixing to the housing tube provides the necessary stability even with large strokes under side load force effect. Microprocessors are built-in to control the soft start and soft stop, as well as stroke lengths, speeds, or forces. It protects the drive from overload, as well as the window and the attachment parts from premature wear. Parallel operation of multiple drives and multiple customer- and object-related configurations is also possible without any issue. These products are ideal for the installation of smoke and natural ventilation systems in larger buildings.

It is possible to mount the spindle drives either via adjustable clamping rings or sliding elements on the housing tube, eye-bolts or clevis brackets in the rear of the housing bottom. The user-friendly, adjustable fixing to the housing tube affords the required stability even with long strokes under the effects of side load forces.
Integrated microprocessors regulate the soft start and soft stop, as well as the stroke lengths, speeds or forces. This both protects the drive against overload as well as the window and the attachment elements against premature wear. The synchronous running of several drives and various customer- and object-specific configurations are also possible without any problem.
Natural Ventilation
Windows are part of buildings, which provide pleasant daylight. Through the need to be opened, an optimal room climate is created with a large amount of fresh air at the workplace and in the home. You can have natural ventilation for comfortable conditions using electromotive operated windows. The drives are controlled through a ventilation control unit, which brings in a controlled amount of fresh air.
The natural ventilation through window drives with controlled flow ensures high air exchange rates and attains very low energy use. Sensors measure weather and temperature information and other environmental conditions through sensors that decode the information and transmit it to the system. Optimal outcomes are obtained using heating, cooling, and sun protection systems. Each individual step of the system is precisely coordinated and scheduled and is based on personal requirements. For smoke ventilation, a comparable sensor-based system can provide security in case of an emergency and permit controlled ventilation with real-time data.
If the drive is installed at the main closing edge, the slim drive housing of the spindle drives protrudes a long way into the room, and requires a relativelynlarge swivelling range. The rigid spindle tube describes a chord with the arch to the upper edge of casement while opening. Spindle drives are therefore used principally for outward-opening windows. The complete drive force is transmitted to the window. The time for opening depends on the load, the stroke length and the speed. Larger opening widths can be achieved by mounting of the spindle drives at the side closing edge.
As an alternative, spindle drives combined with hardware sets can be installed at an acute angle force application to the window frame. Although this transmits part of the drive force into the window hinges, significantly wider opening angles can thereby be achieved with shorter strokes. This requires a free installation width at the window frame of at least 40 mm.

Electric window openers for SHEV and natural ventilation
AUMÜLLER window drives open and close your windows reliably. The electrical window drives provide further driving rain impermeability and joint impermeability. With corresponding control units and sensors, the controlled natural ventilation provides sufficient fresh air and agreeable comfort. The system preserves the environment and saves energy costs. The AUMÜLLER product line provides the appropriate drive solution for each RWA window: For superimposed leaf- or frame-mounting on the primary or secondary closing edge, and for concealed integration into the profile. Elegant design, precise processing, and easy functionality allow the best possible integration into contemporary overall architectural design concepts. Where else equipment meets its limit, we still offer special solutions: In the stairwell, lift, office building, airports, or classroom, providing smoke and natural ventilation systems as well as smoke ventilation solutions dedicated to each environment's specific needs.
