record DFA 127 – swing drive operator

The DFA 127's 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. Even without motor assistance, thanks to ingenious mechanics, optimum power deployment is achieved in the entire door swing area. This is necessary to move the door reliably to its end position against draft resistance, for example, and also complies with the norms and standards of current safety requirements.

The record DFA 127 is available to operate doors in sizes EN4 to EN6. The different spring forces required can be quickly and precisely adjusted on the spot using the special adjustment screw.

This model can be adapted easily to provide additional functionality with no loss of integrity to suit specific requirements such as slower opening, fire resistance, inverse opening in case of power failure and other variations.

Features:

• DIN 18 650-compliant technology, approved worldwide 
• adjustable spring force gives it great versatility
• adjustable to accommodate customer-specific settings
• optimum power deployment in full swing area
• 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 capable of complex functions
• practically silent operation

Variations:

• double swing doors with or without master /slave operation
• power saving mode: adjustable opening of one or both door panels (stretcher opening)
• integrated sequential closing control for double-leaf fire door applications
• interlock function for two single doors installed consecutively 
• direction-oriented opening for oncoming traffic in corridors
