The new ELTRAL KS20 chain drive (24 V)

Small dimensions – massive effect

The new ELTRAL KS20 / 24V chain drive is characterised by its slim shape and its intelligent control electronics. It is quiet thanks to patented chain and PVC housing.

Thanks to a force of 200 N, the chain drive provides secure electromotor-driven opening and closing of bottom-hung windows.

However, the ELTRAL KS20 is also suitable for inward- and outward-opening top-hung, projecting top-hung, parallel and side hung windows with aluminium, steel, PVC or timber profiles.

Thanks to the small dimensions (21 x 28 x 354 mm), concealed installation (frame) is possible as well as surface-mounted installation (sash or frame).
