March 25, 2014 - Eaton announced EVZ explosion-protected pendant light fittings for high-pressure lamps. The light fittings are suitable for installation in hazardous gas (Zone 1 and 2) and hazardous dust (Zone 21 and 22) areas or harsh industrial environments. The EVZ series of Ex-pendant light fittings benefit from an IP66-protected, metallic design. The light fittings are manufactured in accordance with ATEX directive 94/9/EC and latest Ex-standards IEC/EN 60079, which cover the latest requirements for Ex-apparatus. A rugged, copper-free, aluminium housing and tempered glass globe mean the light fittings are suitable for installation in harsh industrial environments, where high mechanical impacts may occur, or where high levels of moisture and dust are present.
No additional guard is required for the light fitting, although additional stainless steel guards are available. As well as a protection rating of IP66 for wet and dusty environments, the EVZ series is also manufactured from materials that are resistant to chemicals and UV light. EVZ light fittings are available in wall, ceiling or pole-mounted versions, in two sizes. The small body version covers a power range of high-pressure lamps from 70W up to 150W. The large body version covers a power range of high-pressure lamps from 250W up to 600W.
All versions in the EVZ series are suitable for HPS (high pressure sodium) lamps and MH (metal halide) lamps (the 600W version is only available for HPS lamps). Ambient operating temperature range is from -40°C to +55°C. Due to their low weight, the EVZ light fittings are easy to handle and mount. For individual light distribution, optional external reflectors are available.
“Not only is the EVZ series mechanically robust, the light fittings are cost effective with a very attractive price-performance ratio,” said Klaus Weyer, Product Line Manager Lighting, Crouse-Hinds division. “This means the EVZ series is suitable for applications in oil refineries, offshore oil and gas platforms, chemicals, petrochemicals and sewage treatment plants. For hazardous dust environments, the EVZ series is suitable for installation in flour mills, sugar processing, food processing, wood and metalworking, and other environments where combustible dusts are present.” “In addition, due to a permissible ambient temperature rating of minus forty degrees Centigrade, the explosion-protected EVZ pendant light fitting can be installed in very low temperature applications,” he added.
Eaton’s Crouse-Hinds division offers a range of cable fittings, enclosures, plugs and receptacles, industrial lighting fixtures, signals and alarms, and electronic components designed for the most demanding environments. The Crouse-Hinds business serves customers in the industrial and manufacturing, mining, oil and gas, solar, infrastructure and other markets.
