The 24 V DC motor of the new VTA commercial door drive runs extremely quietly in comparison to conventional single-phase 230 V AC drives. Despite this, it is strong enough to move sectional doors measuring up to 18 square meters. The VTA can be easily and cost-effectively outfitted with a battery backup. Furthermore, emergency operation of the sectional door is possible via a chain, crank, or unlocking mechanism. Additionally, it is equipped with an automatic force cut-off and can be used with a door surface of up to 14 square meters without active safety components.
