Hospital door DFA 127 INVERSE

swing

The record DFA 127 INVERSE enables doors to open securely and reliably, even without a power supply. During the motor-driven closing cycle, the energy required for opening is mechanically stored using a spring. Should smoke start to fill the building, the independent smoke and heat venting system controls the drive, and the INVERSE opens reliably, even during power failures. The door can therefore be used to allow fresh air to circulate inside buildings, or to vent smoke and heat. Especially suitable for use in: Escape route openings Securing guide routes for persons Venting smoke and heat Special benefits: The opening stop is integrated into the door drive system (no hazard for pedestrians to stumble over) No emergency power supply required to open the door The electromagnetic parking brake means additional electrical opening devices on interior doors can be dispensed with. Universally applicable The record DFA 127 is a universal drive system for the automation of swing doors. It is characterized by sophisticated technology, compact design and especially record’s legendary smoothness of operation. The focus on a broad range of applications makes it a full-fledged drive, suitable for widely differing requirements. Its universal qualities are mainly due to its electro-mechanical construction, and partly due to its modular design. When the door drive motor operates, it simultaneously tensions a spring integrated in the drive housing. The shutting movement uses energy stored in the spring, which, depending on requirements, is also motor-assisted.
