High speed ATEX approved roll doors

DMF can now supply and install Explosion-Proof High speed spiral security doors, in partnership with Efaflex Gmbh. The EFA-SST EX at has the following features

  • For use in explosion protection zones 1, 2, 21 and 22
  • Highest wind load capacity
  • Up to 200,000 operating cycles p.a.
  • Suitable for external and internal applications
  • Offers good security
  • Opening up to 1.0 m/s and closing up to 0.5 m/s
  • Standard sizes up to w=4,000mm x h=5,000mm

The classic high speed door for potentially explosive atmospheres, the EFA-SST EX is excellently suited for both internal and external use. In addition to high operating speeds, it also offers a solid door blade with high wind resistance and optimal sealing. The standard door blade consists of double-walled aluminium laths, which can be supplemented all in or part with optional transparent laths. The door blade is guided by a spiral, without contact minimising wear.

The EFA-SST EX has been developed in accordance with ATEX Directive 2014/34/EU specifically for use in potentially explosive atmospheres for Zone 1 (II 2G IIB T4 GbX), Zone 2 (II 3G IIB T4 GcX), Zone 21 (II 2D IIIB 135°C DbX) and Zone 22 (II 3D IIIB 135°C DcX).

Note that the control cabinet must be installed outside the explosion protection zone.
