From drilling decks and accommodation platforms, to upstream refineries, many oil, gas and petrochemical installations now require equipment to be installed in hazardous areas and ATEX classified zones. Explosive atmospheres can be caused by any number of flammable gases, mists, vapours and combustible dusts. When a sufficient quantity of hazardous material is mixed with air, all that is needed to cause an explosion is a source of ignition such as a spark or even a high surface temperature.
Locations classified into hazardous zones are required by law to be protected from sources of ignition. Whilst there are many UV systems available on the market, there are very few that can meet the strict requirements of the ATEX & IECEX directives for installation into explosive atmospheres and classified hazardous zones.
atg UV Technology are the world’s leading supplier of ATEX certified UV disinfection systems, and have supplied some of the worlds’ leading oil and gas operators such as Statoil, Shell, Transocean, Petronas, Conoco Phillips, GDF Suez, and Total with ATEX & IECEX Zone 1 and Zone 2 rated UV Systems and ATEX certified skid packages.
A unique feature of the atg UV Technology design is the development of the worlds’ first Ex d design for both the control panel and UV Chamber. Ex d equipment utilises a flameproof design that can fully withstand the pressure released from an internal explosion. Using specially engineered Ex d joints, the UV chambers and control panel enclosures will allow the release of expansion gases following an internal explosion to be relieved through the joints, whilst not permitting the flames or any other sources of ignition to be transmitted into the external atmosphere.
Compared to Ex p or purged designs, which use positive pressure from a safe gas supply such as nitrogen to create a safe area within the panel, Ex d solutions are significantly favoured by oil & gas operators. Ex d equipment is proven to be a safer, more robust technology that is typically smaller, lighter and requires significantly less installation and maintenance activity. In addition, due to the complex nature of Ex p designs and the requirement for a constant safe air supply (nitrogen), Ex d solutions are often far more cost effective.
Typically atg UV Technology designs are suitable for ATEX Zones 1 and 2, and are designed for Temperature Classification T3, and Gas Groups IIA, IIB and IIC as standard.
As the world leader for hazardous area solutions, atg UV Technology can provide either standalone UV systems, or fully integrated ATEX skid packages featuring all required equipment such as valves, filters, pumps and instrumentation.
