ATEX - Protective systems

According to the provisions of the Directive 2014/34/EU of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the Member States relating to equipment and protective systems intended for use in potentially explosive atmospheres 2014/34/EU:

  • ‘protective systems’ means devices other than components of equipment which are intended to halt incipient explosions immediately and/or to limit the effective range of an explosion and which are separately made available on the market for use as autonomous systems;
  • ‘group I’ means equipment intended for use in underground parts of mines, and in those parts of surface installations of such mines, liable to be endangered by firedamp and/or combustible dust, comprising equipment categories M 1 and M 2 as set out in Annex I;
  • ‘equipment-group II’ means equipment intended for use in other places liable to be endangered by explosive atmospheres, comprising equipment categories 1, 2 and 3 as set out in Annex I;
  • ‘equipment category’ means the classification of equipment, within each equipment group, specified in Annex I, determining the requisite level of protection to be ensured;
  • ‘intended use’ means the use of a product prescribed by the manufacturer by assigning the equipment to a particular equipment group and category or by providing all the information which is required for the safe functioning of a protective system, device or component.

ROTARY VALVES

Our rotary valves FZC STD are explosion protection systems and are designed and produced in accordance with the provisions of the ATEX directive. They convey bulk materials between two seprate chambers or systems, regulate their flow and at the same time work as certified explosion isolation device.

EXPLOSION VENT PANELS

Venting panels are the most popular way to protect enclosures (such as filters, dust collectors, silos etc) against dangerously high pressure increase caused by explosion inside those enclosures.

EXPLOSION VENTING DEFLECTORS – VIGISPACE

In order to protect people and facilities against explosions that might happen when working with combustible and explosive dust, the flame and the pressure of the explosion need to be guided into defined, safety area. That is why we recommend the VIGISPACE explosion vent deflector.

FLAMELESS VENTING

The VIGIFLAM VQ is a rectangular flameless venting device connected with an internal standard explosion vent panel. The device eliminates the spread of flame and arrests burning particles of the explosion. VIGIFLAM VQ can be used indoors and outdoors which makes the installation designing process much easier.
