Explosive atmospheres
  • Features

    What is ATEX ?

    • It is a term commonly used to describe potentially explosive atmospheres (ATmosphères EXplosibles in French) and standard for protection systems and equipment.
    • Two European directives, ATEX 99/92/CE and ATEX 94/9/CE, and international standards IEC 60079 and IEC 61241, harmonized with EN European standards, apply to this field.
    What is a potential atmosphere?

    According to ATEX, a potentially explosive atmosphere is defined as a mix of flammable substances in the form of gas, vapour, dust (cloud deposit) which, in air under normal atmospheric conditions, can completely or partially catch fire in the form of an explosion when exposed to a source of ignition.

    Since July 1st, 2003, the European directive ATEX 94/9/CE makes compulsory the use of certified component, equipment or assembly when intended for use in potentially explosive zones, gaseous or dusty atmospheres.

    Our solutions:

    We can offer you an ATEX-certified range of wall-mounting enclosures, including steel (Spacial S3DEX), stainless steel (Spacial S3XEX) and polyester (Thalassa PLMEX).  They guarantee safety for every application, in every area classified as “ATEX II2” or “II3”, which mean installations of surface with occasional or rare risks.

    Enclosures are certified as components.  They will be assembled with other ATEX electrical, pneumatic and hydraulic components, among others to form a final solution which, in turn, must be ATEX-certified and subjected to a declaration of conformity.
    All our wall-mounting enclosures comply with standards for protection against the increased risk of explosion in atmospheres charged with gas (G) and/or dust (D).
    The Universal Enclosures offer, designed to be used in group II, is classified as category 2.

    Our range :
    Spacial S3DEX : Industrial environments, equipment rooms
    Spacial S3XEX : Laboratories, food and beverage industries, specific demands in terms of hygiene and corrosion
    Thalassa PLMEX : Seaside, petrochemicals, highly corrosive environments
