The explosion-proof Ex-Lite series of LED escape sign luminaires from COOPER Crouse-Hinds are now able to operate in ambient temperatures down to -40°C. The luminaires are well suited for use in Zone 1 and Zone 21 hazardous areas, including oil, gas and petrochemical applications.

The new extended permissible ambient operating temperature means the luminaire is now suitable for installation in countries where ambient temperatures are extremely low, or in applications where the specified operating temperature is extremely low.

The luminaires also fulfil the requirements of ATEX Directive 94/9/EC and EN 60598, section 2.22 for emergency lighting. The units are therefore suitable for marking escape routes and exits in potentially explosive atmospheres.

The Ex-Lite series utilises white, high efficiency LEDs as the light source, guaranteeing maintenance-free operation, as the illuminant does not need replacing throughout the complete service life of the luminaire, which is approximately 50,000 hours. The supply electronics are also designed for the life of the luminaire, with intrinsically safe LED circuits.

The luminaires are protected to Category II 2G Ex e ib mb IIC T6 (40°C) T5 (50°C) Gb in accordance with the ATEX Directive for use in potentially explosive gas atmospheres (Zones 1 and 2). The luminaire is also suitable for potentially explosive dust atmospheres (Zones 21 and 22) and is certified to Category II 2D Ex tb IIIC T80°C Db IP66 in accordance with the ATEX Directive. The luminaire also complies with the latest equivalent IEC standards for gas and dust.
