Because it distributes the force evenly, it is suitable for wide and heavy sashes, fanlights and rooflights.<\/p>\n<h3>VS-DKA 800 double chain drive overview<\/h3>\n<p>The VS-DKA 800 double chain actuator (24 V\/230 V) with 800 N thrust is designed specifically for large windows, skylights and rooflight domes. Two chains working in parallel give the actuator high stability and even force transmission. It is low-maintenance, robust and suitable for ventilation and <a href=\"https:\/\/ventsystems.de\/en\/smoke-and-heat-extraction-shev-why-high-quality-drives-are-crucial-in-case-of-fire\/\">Smoke and heat exhaust ventilation (SHEV) applications<\/a> . For use in smoke ventilation systems, the actuator, the window and an approved smoke control panel must be matched to one another and verified for each project \u2013 we will be happy to advise you.<\/p>\n<h3>Selection, assembly and further information<\/h3>\n<p>Double chain drives distribute the power across two chains and are therefore suitable for wide or heavy wings.

The VS-DKA 800 distributes the force evenly across the sash via two parallel chains. This ensures stability on large windows, fanlights and rooflight domes.<\/p>\n<h3>Which voltage and stroke are available for the VS-DKA 800?<\/h3>\n<p>The VS-DKA 800 is available in 24 V and 230 V with 800 N of thrust. You select the stroke length in the shop between 100 and 1,400 mm.<\/p>\n<h3>How much force does my window need?<\/h3>\n<p>That depends mainly on sash weight, opening width and installation position.
