DTN 40

Swing-door drive for interior doors

  • Barrier-free living: doors within apartments
  • Ergonomic workstations: doors in office and business areas
  • Hygiene: doors in practices, clinics or care facilities
  • Silent: The design of the compacthousing of the DTN 40 is consciously low-key. The drive operates
    more or less noise free.
  • Elegance: The roller track with lever arm fits inconspicuously into the overall picture
  • Comfort : You can also operate the drive without a complex electrical installation.
  • Quality : made in Germany All GU Automatic products are developed and produced in Germany subject to strict quality controls.

High-performance on standard and fire protection doors

Swing-door drives open up new opportunities: automatic opening and closing fire and smoke protection doors as well as interior and exterior doors increase freedom of movement and safety in public buildings. Comfortable access is provided via radar motion sensors, push-buttons or an access control system. A combination of multi-point lock and motor-driven shoot bolt lock is recommended for entrance doors in the facade. This makes accessibility, burglar protection and escape route safety a reality.

Universal application
All applications can be implemented using only one swing-door drive:

  • 1- and 2-leaf swing doors
  • Fire doors
  • Escape doors
  • Push-open or pull-open
  • For door leaf weights up to 600 kg
  • For door leaf widths up to 1600 mm
  • Patented energy-store consisting of two spring assemblies which can be adjusted separately
  • Patented closing damping via the dynamic effect of the drive motor
  • Door closer effect
  • Mechanical closing sequence control for 2-leaf fire protection doors or for doors in escape routes concealed under the drive cladding
  • Modular system reduces inventory management
  • Quiet running properties make it particularly suitable for use in noise-sensitive areas, such as offices or hospitals
  • Tested quality
    • Type-tested by TÜV and certified to EN 16005
    • Tested by VdS and material testing office in Germany in accordance with DIN 18263-4/EN 1158
