Designed to open and close windows in difficult to reach areas, electric screen openers, or actuators, are exceptionally handy.
You can connect the electric sliding window opener with all types of sensors so that it could open and close automatically when it’s rainy and gas leak.

They work with a motorised folding arm that is attached to a screen. The arm starts in a folded placement, however as it is run by the electric motor, it begins to unfold. The arm is positioned in a manner that as it begins to unfold, the screen begins to open. To close a home window, the arm begins to fold back again up into its primary position, bringing the home window to a close.

Chain actuators work much like rack and pinion actuators. A chain engages with pinions that have been installed on a drive shaft inside an external casing. As the pinions spin, the links of the chain are rotated through the casing at a 90-degree position. This directs the chain right into a rigid, directly form, which is highly resistant to tension and compression. For an electric window opener, the chain has been mounted on a window. In order the chain is directed right into a straight form, the screen is pushed open. And as it retracts into the casing, the window closes.
These are usually suited to side hung windows or doors, because they offer a 90-degree opening. They are also called folding arm actuators and may be designed to open inwards, outwards or both ways.
