Aumuller KSA D S12 24 V DC
Power, Control, Safety: large windows in roofs and facades require smart drive solutions that can always be relied upon. KSA chain drives from AUMÜLLER operate with forces of up to 1200 N. An electronic speed control system ensures smooth engine running and low noise development. The KSA TWIN or KSA D versions with two chains and double the force guarantee safety even in the most challening situations and meet the highest demands.

Universally applicable and powerful: the chain drive KSA D is the optimal solution for narrow and heavy window sashes – thanks to an extremely short housing length as well as a high pushing force due to two counter-rotating, back-stiff chains made of stainless steel.
