The WMU888 chain actuator (inset) is designed as a stylish alternative to spindle window actuators where an actuator that does not detract from the visual impact of a building is preferred.
GOOD DESIGN ISN’T OVER UNTIL WINDOWMASTER’S FAT LADIES SING
WindowMaster (www.windowmaster.com), Europe’s largest provider of natural ventilation solutions, has launched a new high performance chain actuator for large and heavy windows.
Designed as a stylish alternative to spindle window actuators where an actuator that does not detract from the visual impact of a building is preferred, this cost effective WMU888 unit (affectionately dubbed the three fat ladies) can control windows requiring a force of up to 1,000 newtons to open.
The use of a chain rather than a bulky spindle means that the actuator does not compromise the overall aesthetic of the architectural design, enabling a feeling of light and space to be retained.
The actuator incorporates the company’s state of the art MotorLink™ digital data communication technology and can be used in conjunction with WindowMaster’s intelligent controllers to provide improved control and functionality. The actual position of the window is logged and stored in a secure memory within the electronics of each actuator. Therefore, position information is retained even in the event of power loss.
With the MotorLink™ technology the actuators also have the ability to operate in two different speeds – slow and silent speed during automatic control and a faster speed during manual operation to provide an audible and visual indication of the activation.
WMU 888 actuators can be programmed to stop and reverse if an obstacle is detected when closing to provide some pressure safety function. They also have a small reverse function when the windows are fully closed in order to prolong the life of the weather seal on the window sash because the set point for closing power can be adjusted according to window type.
Suitable for both smoke and comfort ventilation and for standard control panels or intelligent MotorLink™ panels, the WMU888 chain actuator is programmable – even after installation – to suit specific requirements including speed of opening and closing, sound level, pressure and traction force.
The actuator is housed in a classic design anodized aluminium cladding suitable for surface mounting on top hung, bottom hung, turning and pivoting roof windows and light domes.
