Explosive atmospheres, often referred to as EX zones, are some of the most challenging environments in which computers and other electrical equipment and components may be located. Yet, in certain industries, such as oil and gas, mining, the chemical and the petrochemical industries, having electrical equipment in these areas are a necessity. EX zones are divided into two sub-groups: Zone 0, 1 and 2 refer to areas with a gas, vapour or mist hazard, whereas zones 20, 21 and 22 refers to areas with a powder or dust hazard.
In 2003, the EU introduced the ATEX directives in order to ensure the safety of employees working in an explosion risk area. All organizations based within the EU are required to follow these directives and use only ATEX certified equipment – both electrical and mechanical – within EX zones. ATEX certified computers and Panel PCs typically have reinforced, robust enclosures and screens, designed to withstand a potential explosion. Additionally, these components must satisfy the required IP ratings in order to prevent dust and water to penetrate the enclosure.
Hatteland Technology offers a selection of some of the best EX zone computers available on the market.
