HALTON MARINE NAVIGATOR 3/2007
Halton Marine products comply with ATEX
Halton Marine develops, manufacturers and markets high-quality products and solutions specifically designed for demanding conditions such as marine, Oil&Gas and navy applications. Demanding conditions require that the equipment chosen for applications is top-class. Several Halton Marine products comply with ATEX.
What is ATEX? ATEX is abbreviation from French words "ATmospheriques EXplosives". ATEX product directive is a European Directive (94/9/EC) valid for products to be used within an explosive atmosphere. The directive defines explosive atmosphere as a mixture of:
a) flammable substances, gases, vapours, mists or dusts b) with air c) under specific atmospheric conditions d) in which, after ignition has occurred, combustion spreads to the entire flammable mixture
An atmosphere with the potential to become an explosive atmosphere during operating conditions and/or under the influence of the surroundings is defined as a potentially explosive atmosphere. Products covered by directive 94/9/EC are defined as intended for use in potentially explosive atmospheres. In essence ATEX certified products are safe to use in hazardous areas defined by the classification of the product. The ATEX classification of the product is defined by the product's and its components properties that prevent the ignition the explosive environment. Such properties could be flame-proof enclosures, intrinsically safe circuits or relatively low surface temperatures.

This is the basic ATEX classification information that can be found in Halton Marine ATEX products. The classification defines the environment in which the product is designed to be used. It tells that the product is ATEX certified for use in areas other than in mines or in mining equipment, the product can be used in Potentially Explosive areas (classified as ATEX Zone 1) and that the gases in the environment can be as dangerous as acetylene and hydrogen. It is allowed to use the product in any ATEX classified area that has equal or less hazardous rating than marked on the product. All this of course requires ATEX knowledge from both the buyer and the seller of the product. The buyer needs to know at least the rating of the hazardous area and the seller needs to know if the product fulfills the requirements.
All ATEX products are sold with a Declaration of Conformity. The declaration is only valid in conjunction with the instructions contained in the installation manual relating to the safe use of the product throughout its service life. The instructions relating to the operating conditions and maintenance are very important, as the certificate is invalidated if the instructions are found not to have been adhered to during operation of the product. A single Declaration of Conformity may be issued for multiple similar products in a project.
Halton Marine currently offers ATEX products in the following product categories:
- Fire Dampers (FDB2, FEX and FDL)
- Dampers (UTG, UTT, UTK and UTP)
