\"Atex<\/a><\/p>\n

The ATEX directive, if you are not familiar, is the EU directives that describe what equipment and work environment is allowed in the presence of an explosive atmosphere. \u00a0The ATEX equipment directive 94\/9\/EC\u00a0covers equipment intended for use in potentially explosive atmospheres.<\/p>\n

For ignition to occur, there must be three things present. \u00a0First a sufficient amount of flammable or combustible substance. \u00a0Secondly, air or oxygen, the fuel that allows things to burn. \u00a0Third, an ignition source. \u00a0The ignition source is typically a spark or a\u00a0hot enough surface for conditions.<\/p>\n

The directive provides a classification based on the equipment group and the equipment category. \u00a0Equipment Groups are divided into two – group I<\/span>, which are mines and group II<\/span>, which are above ground. \u00a0Equipment Categories further describes the equipment protection with \u00a0atmospheric conditions and protection level. There are five equipment categories – M1<\/span>– Methane & Dust, Very High Protection, M2<\/span> – Methane & Dust, High Protection, 1<\/span> – Gas, Vapor, Mist, Dust, Very High Protection, 2<\/span> –\u00a0Gas, Vapor, Mist, Dust, High Protection, 3<\/span> –\u00a0Gas, Vapor, Mist, Dust, Low\u00a0Protection.<\/p>\n

Each Equipment Group\/Equipment Category\u00a0is acceptable for for a certain Zone classification. \u00a0Zone 0<\/span> is an area with an explosive atmosphere of\u00a0gas, vapor or mist present continuously, for long periods, or frequently. \u00a0Zone 1<\/span> is an area with an explosive atmosphere of\u00a0gas, vapor or mist present occasionally. \u00a0Zone 2<\/span>\u00a0an an area with an explosive atmosphere of\u00a0gas, vapor or mist not likely to occur or for a short duration.<\/p>\n

The zones\u00a0expanded further to describe areas with combustible dust. \u00a0Zone 20<\/span> is an area with a cloud of combustible dust is\u00a0present continuously, for long periods, or frequently. \u00a0Zone 21<\/span>\u00a0is an area with a cloud of combustible dust is\u00a0present occasionally. \u00a0\u00a0Zone 22<\/span> is an area with a cloud of combustible dust not likely to occur or for a short duration.<\/p>\n

Each Zone, therefore, \u00a0has an associated equipment category that is suitable for operation in that particular Zone as follows-<\/p>\n

 <\/p>\n\n\n\n\n\n\n
Atex Zone<\/strong><\/td>\nExplosive\/Combustible Environment<\/strong><\/td>\nAtex Category<\/strong><\/td>\n<\/tr>\n
Zone 0, 20<\/td>\nContinuous<\/td>\nCategory 1<\/td>\n<\/tr>\n
Zone 1, 21<\/td>\nOccasional<\/td>\nCategory 2<\/td>\n<\/tr>\n
Zone 2, 22<\/td>\nNot Likely<\/td>\nCategory 3<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

 <\/p>\n

By defining the Equipment Group and the Equipment Category, we know what Zone the device will be suitable for. For example, a machine approved Equipment Group I Category 2 is suitable for mines and has high protection against explosion, thus \u00a0would be acceptable for Zone 21.<\/p>\n

All Apex Dynamics gearboxes are rated Equipment Group II Category 2. \u00a0The Declaration of Conformity can be downloaded here<\/a>\u00a0or from our website on\u00a0the press page<\/a>.<\/p>\n

Of course, a gearbox by itself has no potential to create a source of ignition. \u00a0We have to use our heads, let common sense prevail and make decisions on the evidence we have. \u00a0Each application is different and operating parameters can change\u00a0what equipment group the completed machine will fall in.<\/p>\n
