In addition to a standard frequency converter and a microprocessor control, the EFA-SRT® EX for indoor use includes all typical basic characteristics of state-of-the-art door technology, such as dynamic door leaf tension and emergency opening via spring systems in the door cases. A hand lever at the door case allows for quick emergency opening of the door system, e.g. in case of power failure. We use a black, non-transparent ATEX special curtain as the door leaf.
