Atex Zone 1 Vs Zone 2

This classification is for an EC (ATEX) compliant system for surface equipment that has an equipment category of 2 (Zone 1) and is for gasses as opposed to dusts The protection concept is "d" which is flameproof, the gas group is IIC and the maximum allowable temperature is 0°C.

Atex zone 1 vs zone 2. Mostly green (ATEX zone 2) and purple (ATEX zone 1) ATEX zones, equipment groups and categories When the ATEX zone is clear, the table helps you to find the accessory equipment ATEX equipment is classified into equipmentgroups. ATEX Zones – Zones are defined in the ATEX Workplace Directive 1999/92/EC, as follows Gas, Vapor, or Mist Zone 0 – a place in which an explosive atmosphere consisting of a mixture with air of flammable substances in form of gas, vapor or mist is present continuously or for long periods or frequently. Hazardous areas declared by the employer or facility owner are classified in Zones The classification given to each Zone, its size and location are dependent on the likelihood of the environment being explosive and the persistence or length of time if it is ATEX 14/34/EC (ATEX 95 / Equipment Directive).

Zone 1 (gases/vapours) an area in which an explosive mixture is likely to occur in normal operation Zone 2 (gases/vapours) an area in which an explosive mixture is not likely to occur in normal operation and if it occurs it will exist only for a short time ATEX zones for dust.

See the following chart which shows the zones under both IECEx / ATEX and the North American system of Classes & Divisions Areas where potentially explosive liquids, gases or dust are being produced, refined or where some repeated contact is likely are generally classified as Zone 1 Conversely, examples of Zone 2 areas are storage areas, maintenance workshops and other ancilliary areas adjacent to the main production areas Temperature Classifications. A atex zone 1 is similar to a zone 0 However, a zone 1 is a place in which an explosive atmosphere is likely to occur in normal operation occasionally, instead of a continuously presence of a hazardous atmosphere Atex zone 2 In a atex zone 2, a explosive atmosphere is not likely to occur in normal operation.

Zone 1 flammable atmosphere possible but unlikely to be present for long periods Zone 2 flammable atmosphere unlikely to be present except for short periods of time typically as a result of a process fault condition Dusts ;. Zone 1 is an area that is classified ‘as a place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapours and mists is likely to occur occasionally during normal operation’, whereas Zone 2 is an area that is classified ‘as a place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of gas, vapours and mists is not likely to occur in normal operation but if it does occur, it.

Regarding ATEX 99/92/EC Directive, the requirement is that Employers must classify areas where potentially explosive atmospheres may occur, into zones The classification given to a particular zone, and its size and location, depends on the likelihood of an explosive atmosphere occurring and its persistence if it does.

Zone 0, 1, 2 – These are zones specifically for atmospheres with hazardous gases, vapors, and mist Zone 0 – Explosive mixtures are present continuously Category 1 equipment required Zone 1 – Explosive mixtures are present intermittently Category 2 or 1 equipment required Zone 2 – Explosive mixtures are present abnormally or infrequently Category 3, 2, or 1 equipment required. Home / Hazardous Locations Motors / Zone 2 ATEX & IECEx Motors ATEX & IECEx Zone 2 Increased Safety, and nonsparking electric motors The environments are classified as Zone 2, groups IIA, IIB and IIC, and as Zone 22, groups IIA, IIB and IIC. Equipment of category 1 is intended for use in areas in which explosive atmospheres caused by gases, vapors, mists or air/dust mixtures are likely to occur Category 2 comprises equipment designed to be capable of functioning in conformity with the operational parameters established by the manufacturer and of ensuring a high level of protection.

This classification is for an EC (ATEX) compliant system for surface equipment that has an equipment category of 2 (Zone 1) and is for gasses as opposed to dusts The protection concept is "d" which is flameproof, the gas group is IIC and the maximum allowable temperature is 0°C. Certified weatherproof to IP66;. Many people have heard terms like Class I, Division 2, Group E, or ATEX zone 21 but many of our customers only know what certification they require with little understanding of what they mean, so we thought it would be appropriate to write a blog post to help customers understand the broader implications of these terms.

Suitable for both Zones 1 & Zone 2 hazardous areas;. ATEX Directive 14/34/EU is a «new approach» directive that applies to protective systems against explosions as well as all equipment used in or related to explosive atmospheres, such as electrical and nonelectrical equipment, components and safety devices, control and adjustments necessary for the safe operation of this equipment and protective systems. Zone 1 classified location An area where ignitable concentrations of flammable gases, vapors or liquids are likely to exist under normal operating conditions As a guide for Zone 1, this can be defined as 10–1000 hours/year or 01–10% of the time Class I, Division 2 or Zone 2 classified locations.

Zone 1 is considered a hazardous location where dangerous gases, vapors or mists are likely to exist in normal operating conditions on occasion Zone 2 is considered a hazardous location where dangerous gases, vapors or mists are not likely to be present under normal operating conditions, but if they are, they are only present for a short period of time. Distance the zone classification is normally zone 2 or Safe Area This is one of the reasons why more than 85% of the Flame Detectors with EEx d housings, which are suitable for zone 1, are actually mounted in zone 2 Engineers design plants and installations with smaller ATEX zones 1 due to the high cost of operation of such hazardous areas That is why zones 2 in the Industry are getting larger.

Can be installed in conditions ranging from °C to 40°C;. Areas within these two kinds of explosive atmospheres are each divided into three subzones Although the zones characteristics are identical for both gas and dust, their numbering is different Zone 0, 1 and 2 refer to gas and Zone , 21 and 22 refer to dust Permanent presence of explosive gasses or combustive dust. Equipment of category 1 is intended for use in areas in which explosive atmospheres caused by gases, vapors, mists or air/dust mixtures are likely to occur Category 2 comprises equipment designed to be capable of functioning in conformity with the operational parameters established by the manufacturer and of ensuring a high level of protection.

I A location made hazardous by the presence of flammable gas or vapour that may be present in the air in quantities sufficient to produce an explosive or ignitable mixture II A location made hazardous by the presence of combustible or electrically conductive dust. There are three area category types, with Category 1 requiring a very high level of protection and defined as an area having a permanent or prolonged risk of explosions (Zone 0), Category 2 which requires a high level of protection and has a frequent risk of an explosive mix being present in the air (Zone 1), and Category 3, specified as requiring a normal level of protection with a small chance of an explosive mix forming (Zone 2).
