AUMÜLLER Hardware systems
Electric hardware systems for natural ventilation
AUMÜLLER hardware systems form a loose collection of various spindle drives, locking drives, bracket sets and control modules. These can be used for the mounting of window drives at an acute angle of attack (>12°) to the window frame of the side closing edge of façade windows or skylights. In both cases, a large opening angle of approx. 90° can be achieved with side-hung windows and 160° with skylights, all with a relatively short stroke. The hardware sets from AUMÜLLER for façade windows are known under the designation “RWA hardware systems”, and those for skylights under “Skylight hardware systems”.
Due to the specially short basic construction length of the spindle drives from AUMÜLLER, RWA hardware systems can also be installed without any problem to windows with low window heights. Two spindle drives are used, with a force of 600 N for side-hung windows and 1000 N for bottom-hung and top-hung windows. The mounting of the window openers at the side closing edge necessarily requires a window locking drive, in order to ensure integrity against driving rain and impermeability of the joint along the complete joint length of the window.
The opening angles of the leaves depend on the drive stroke, the bracket height and the distance of the point of attack to the sash hinge. Further details should be taken from the individual product descriptions.
For skylight hardware systems, drives of the PLA16 with 1600 N and PLS30 with 3000 N are used. Drives with integrated microprocessors regulate the soft start and soft stop and stroke length, speed and force. This both protects the drive against overload, and the skylight, attachment and hardware parts against premature wear. The parallel connection of several drives without additional modules, as well as various customer- and object-specific configurations are possible without any problem. Skylights up to a size of 1.25 x 2.50 m can be opened to approx. 160° within 60 seconds. The snow loads to be considered depend on the drive force and the skylight surface area. These can be taken from the technical documentation.
AUMÜLLER hardware systems can be used in SHEV systems and as well as for natural ventilation via automated windows in façades.
The window openers are either installed surface mounted or integrated into the profile. The preferred installation locations are inward opening side-hung, bottom-hung, top-hung windows.
The tandem operation of two window drives in sequence with different locking drives is possible without any problem.
The AUMÜLLER LK fitting system can be used in skylights of different manufacturers, such as Eternit, Eberspächer or Lamilux. It can also be easily adapted to other skylight systems.
The linked product series describe only some of the possible combinations of window drives and window locking drives with fastening elements. We will be happy to put together further combination possibilities tailored to your requirements on the principle of the hardware sets. Please feel free to contact us for this information.
