Patlite introduces signalling devices for hazardous areas

16Nov

Patlite presents a new series of signalling devices for aggressive environments and explosive atmospheres. In addition to the explosion-proof and maintenance-free LED signal towers EDLM and EDWM, which are ATEX 94/9 EC compliant and are suitable for zone 1 and 2, Patlite also offers visual, audible and hybrid products which are suitable for zones 2 and 22.

The innovative, explosion-proof signal towers EDLM (3 coloured LED modules) and EDWM (5 coloured LED modules) are housed in high-strength aluminium alloy enclosures. Their pressure- and flame-proof housings are IP66 rated.

The terminal blocks of the EDLM and EDWM models are easy to locate, and these signal towers are suiotable for flush, wall and horizontal mounting.

The EDLM type comes with patented prism facet LED modules in the colours red, yellow and green. The EDWM type is available with five LED modules in red, yellow, green, blue and transparent.

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

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

Energy-efficient LED lights

The series AR-070 and AR-078 are signal towers with up to five LED modules and a diameter of 40 or 60mm. The signal lights are approved for zone 2 and 22 (gas and dust). 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 the colours transparent, yellow, red, blue and green – as well as the main body are made of strong synthetic materials. They withstand even high pressure and heat as well as damage caused by acid or bases.

The signal towers reach IP65 protection. That allows installation even in damp or dusty environments.

The 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 alarm sounds with an 85dB (at 1 m) output. The type with alarm sound reaches protection IP54.

Large product spectrum

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

All explosion-proof Patlite signalling devices comply with the standard CE/ATEX/NEC certificates.
