Smoke Extraction and Ventilation

Smoke Ventilation systems
This system safes human lives. The faster smoke finds a way out, the faster the persons inside the building can rescue themselves and the more successful the rescue forces can be. AUMÜLLER ferralux® guarantees safety in staircases and elevator shafts, in office buildings as well as in airports and class rooms with efficient control units, drives and natural smoke and heat exhaust systems (NSHEV).
2. Electric window openers for SHEV and natural ventilation
Window drives which in the event of fire reliably open SHEV windows save human lives. And if there is no fire, they ensure adequate day-by-day ventilation, providing pleasant comfort due to controlled natural ventilation. That protects the environment and also reduces energy costs. The AUMÜLLER product range offers the adequate drive solution for every SHEV window: For surface mounting on the main or side closing edge of casement or frame profilrs, as well as for concealed integration into the profile. Elegant design, precision processing and convenient functionality enable the optimum integration into modern overall architectural design concepts. Where others reaches its limits, we still provide special solutions: In the staircase and in the lift shaft, in the office building as well as in airports or classrooms.
Chain Drive
Chain drives from AUMÜLLER have a slim and attractive, robust housing, which encloses the microprocessor-controlled electronics, the aluminium 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. Rigidbacked 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.

Spindle Drive
AUMÜLLER spindle drives have attractive, round or rectangular continuous aluminium housings with end caps of aluminium or plastic. The housing length is determined by the type-dependent fixed, basic construction length, which is in turn specified by the microprocessor-controlled electronics and the motor-gear unit, as well as the variable, stroke dependent length of the spindle housing.
The ball bearing spindles with end position damping are made of highquality stainless steel or phosphated steel. The opening mechanisms consist of spindle tubes made of stainless steel or anodized aluminium. The spindle tubes are provided as standard with fixed or replaceable eyebolts for swivelling mounting to various casement brackets. 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 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
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 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.
