Patlite explosion-proof signaling products

16 July 2012

Patlite launched a new series of signaling devices in 2011, which have been specially designed for tough environments and explosive atmospheres. EDLM and EDWM series explosion-proof and maintenance-free LED signal towers are ATEX 94/9 EC compliant and suitable for zones 1 and 2, and Patlite also offers visual, audible and hybrid products which are suitable for zones 2 and 22.

EDLM and EDWM explosion-proof signal towers (with three and five coloured LED modules respectively) come with a high-strength main body made of aluminium alloy. The pressure- and flame-proof housing is IP66 rated and has been designed for use in potentially explosive atmospheres.

The terminal block of the EDLM and EDWM models is found at the back and provides easy access to the signal tower. The signal towers are suited for flush mount, wall mount and horizontal mount.

EDLM comes with patented prism facet LED modules in red, yellow and green. EDWM comes with LED modules in red, yellow, green, blue and transparent.

The Japanese Tokuyama group is planning to install a fair quantity of EDWM signal towers at its polycrystalline silicon production plant in Malaysia.

“Besides providing safety for our co-workers and machines, the model EDWM-502 explosion-proof LED signal towers help us to improve quality control and productivity”, explains a Tokuyama company spokesman. The company says it values the signal towers because they are highly dependable, maintenance-free and offer a long lasting serving life.

Series AR-070 and AR-078 signal towers have up to five LED modules and a diameter of 40 or 60 mm. The signal lights are resistant against gas or dust explosions and are approved for zones 2 and 22. The energy-efficient LED modules (with a Patlite patented prism cut) provide full and brilliant illumination.

Vertical and horizontal cut lenses in combination with a double-reflection system enhance the diffusion of the LED illumination. The LED modules – available in transparent, yellow, red, blue and green – as well as the main body are made of strong synthetic materials. They are built to withstand high pressure and heat as well as damage caused by acid or bases, and are rated to IP65 allowing use in damp or dusty environments.

AR-078 and AR-070 series signal towers can be either flush or wall mounted and are available with one to five LED modules. They can also be ordered with a flashing/non-flashing function and/or two super-loud alarms with an 85dB output at 1m. The alarm version is rated to IP54.

Explosion-proof products that are suitable for Zone 2 and 22 also include LKEHFE/EXN and LKEHFV/EXN hybrids, EWH24/EXN and PVW04JF/EXN signal horns, as well as the LED working lights of the CLA series and the CLF2024/EXN and CLT3024/EXN bar lights.

All Patlite explosion-proof signaling devices comply with CE/ATEX/NEC standards.
