WindowMaster this week announced that the Underwriters Laboratories Inc. (UL) approved the newly released window actuator WMU 831/851/852 for automated natural ventilation, setting the stage for energy efficient building technologies in the US.
Last year WindowMaster released a new state-of-the art window actuator that comes in three variants for automated natural ventilation. The actuator contains attributes and features, that have long been sought by the market along with the ground breaking TrueSpeed™ technology. Now the actuator has also been UL listed for the North American market, which enables enhanced use of energy efficient natural ventilation.
The WMU 831/851/852 approval builds on WindowMaster’s commitment to offering building professionals in North America a range of possibilities that effectively address the complex needs of energy efficiency, architectural aesthetics and healthy indoor environments.
With the new window actuator in three variants, North American building professionals now have a larger variety of medium sized actuators to pick from. The three variants are different in strengths and speed, which enables the customer to pick the right actuator depending on their specific needs. They all come with an entrapment protection function, which enables them to be integrated into windows that are positioned below 8 ft. from the floor.
Furthermore, a new PCB has been developed to the three actuator variants. The PCB allows more programming space and an inbuilt five terminals connector, which will ease installation of the actuator and let the user directly connect the cable and pressure safety strips into the connector plug.
TrueSpeed™ – Introducing a new, innovative feature
All three variants of the new WMU actuator come with the new TrueSpeed™ technology developed by WindowMaster. With TrueSpeed™ it is now possible to synchronize the opening of all windows. While MotorLink® by WindowMaster allows you to connect up to four actuators so you can open the automated windows simultaneously, TrueSpeed™ allows you to connect the MotorLink® lines meaning that you can now open all windows in sync. Moreover, TrueSpeed™ can slow down the actuator movement (down to 1mm per second), which enables the actuators to run completely silent and give the user a higher degree of control.
Styling and specifications
The new WMU actuator is the smart choice for high quality and power. In fact, the window actuator variants deliver up to 500N in a classic WindowMaster façade actuator. This is great strength for a medium sized chain actuator. Multiple window types can use the WMU 852/851/831 meaning that the product will be available for a large group of contractors, façade builders and others using, planning, or building with natural ventilation.
