For most windows a chain actuator from \u20ac65 net is enough; for heavy sashes and skylight domes a spindle or rack-and-pinion actuator.<\/p><h2 class=\"wp-block-heading\">Which types are there?<\/h2><ul class=\"wp-block-list\"><li>Chain actuator: slim, mounted on the frame, ideal for tilt and top-hung windows<\/li><li>Spindle or linear actuator: for skylight domes, roof windows and long strokes, from \u20ac110 net<\/li><li>Rack-and-pinion actuator: for heavy sashes, continuous rooflights and sawtooth roofs, from \u20ac105 net<\/li><\/ul><h2 class=\"wp-block-heading\">How to choose the right window opener<\/h2><ul class=\"wp-block-list\"><li>Check the opening type: tilt window, top-hung window, roof window or skylight dome<\/li><li>Define the stroke: how far the window should open, usually 100 to 400 mm<\/li><li>Calculate the force: sash weight and mounting position determine the required push and pull force<\/li><li>Choose the voltage: 24 V for control units and sensors, 230 V for direct connection<\/li><\/ul><h2 class=\"wp-block-heading\">Operation and control<\/h2><p class=\"wp-block-paragraph\">The simplest option is a ventilation switch from \u20ac11.99. With a ventilation control such as the VS-C24-7A from \u20ac60 net, several actuators can be operated together and rain or wind sensors can be connected so the window closes automatically when it rains.<\/p><p>For tilt and bottom-hung windows there is a separate overview with suitable drives: <a href=\"\/en\/tilt-window-drive\/\">Windows Drive<\/a>.<\/p>\n<h2 class=\"wp-block-heading\">Frequently asked questions<\/h2><h3 class=\"wp-block-heading\">Can I retrofit an electric window opener?<\/h3><p class=\"wp-block-paragraph\">Yes. Most existing tilt, top-hung and roof windows can be retrofitted without a new window. The 230 V connection must be made by a qualified electrician.<\/p><h3 class=\"wp-block-heading\">How much does an electric window opener cost?<\/h3><p class=\"wp-block-paragraph\">At Vent Systems a chain actuator costs from \u20ac65 net. With a switch, the material for one window is around \u20ac77 net; with a control unit and rain sensor accordingly more.<\/p><h2 class=\"wp-block-heading\">Matching products and tools<\/h2><ul class=\"wp-block-list\"><li><a href=\"https:\/\/ventsystems.de\/en\/product\/vs-ka\/\">VS-KA chain actuator<\/a><\/li><li><a href=\"https:\/\/ventsystems.de\/en\/product\/vs-la\/\">VS-LA linear actuator<\/a><\/li><li><a href=\"https:\/\/ventsystems.de\/en\/product\/vs-za-800\/\">VS-ZA 800 rack-and-pinion actuator<\/a><\/li><li><a href=\"https:\/\/ventsystems.de\/en\/product\/vs-ls7\/\">VS-C24-7A ventilation control<\/a><\/li><li><a href=\"https:\/\/ventsystems.de\/en\/calculate-chain-length-for-window-drive\/\">Calculate the stroke<\/a><\/li><li><a href=\"https:\/\/ventsystems.de\/en\/calculate-the-thrust-of-window-drives\/\">Calculate the thrust<\/a><\/li><li><a href=\"https:\/\/ventsystems.de\/en\/send-a-photo\/\">Send a photo: let us find the right actuator<\/a><\/li><\/ul>","protected":false},"excerpt":{"rendered":"<p>Ein elektrischer Fenster\u00f6ffner \u00f6ffnet und schlie\u00dft Kipp-, Klapp- und Dachfenster per Taster, Funk oder Steuerung.
