Explosion-Proof Light Fittings for T5 Bi-Pin Lamps
Cooper Crouse-Hinds has launched explosion-proof light fittings for T5 bi-pin fluorescent lamps for use in Zone 2/22 areas such as oil refineries, chemical plants and onshore/offshore installations. The T5 bi-pin lamps, which measure 16mm in diameter, are certified for use in Zones 2 and 22 in accordance with the Atex and IECEx standards. The new nLLK 10 Ex-light fittings incorporate all the features of the company's existing nLLK 08 series of Ex-light fittings for Zone 2/21 T8 fluorescent lamps, which measure 26mm in diameter.
However, the new nLLK 10 series is fitted with special Luxtronic EVG electronic ballast technology (including end-of-life setup and switch-off), which provides improved safety, lighting quality and significant energy savings. The end-of-life circuit enables the lamp to be monitored and switched off safely when the end of life has been reached. Gordon Low, marketing segment manager at Cooper Crouse-Hinds, said: 'In terms of installation and maintenance, the nLLK 10 series is very cost effective and easy to install.
'This is due to the options for either a loop in and out or through-wired arrangement, coupled with easy-access terminals. 'In addition, installation is further simplified by a double-sided safety lock, with 10 or 20 latch points, which enables the protective bowl to be hinged on both sides. 'This means that the light fitting can be mounted without having to be concerned with which way the bowl opens,' he added. The nLLK 10 series is suited to indoor use in Zone 2/22 hazardous gas and dust areas, including oil refineries, chemical plants and onshore and offshore installations.
The light fittings are also suitable for outdoor use in high ambient temperatures. The nLLK 10 series is protected to IP66 and operates in ambient temperatures from -25C to +50C. Rated voltage is 220-240VAC/VDC and 50/60Hz. The nLLK 10 series is currently available in two sizes: 2 x 14W HE and 2 x 28W HE. These versions can be fitted to the housings of existing nLLK 08, 18W or 36W T8 lamps, with or without through-wiring. A 2 x 35W HE version of the nLLK 10 series will be available later in 2011.
