PATLITE explosion-proof products

23 October 2014

PATLITE presents a new series of signaling devices, which have been especially designed for rough environments and explosive atmospheres.

Besides explosion-proof and maintenance-free LED signal towers of the EDLM and EDWM series, which achieve ATEX guideline 94/9 EC and are suitable for zones 1 and 2,

Safely encased

The innovative, explosion-proof signal towers EDLM (3 coloured LED modules) and EDWM (5 coloured LED modules) come with a high-strength main body made of aluminium alloy. Thanks to their pressure- and flame-proof housing they are IP66 certified. They have been designed for use in potentially explosive atmospheres in environments such as the oil & gas, chemical and petrochemical industries, and anywhere there are combustible dusts such as in the food industry.

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.

The EDLM type comes with patented prism facet LED modules in the colours red, yellow and green. The EDWM type is available with 5 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 explosion-proof  EDWM-502 LED signal tower model 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 serving life.

Energy-efficient LED lights

The AR-070 and AR-078 series are signal towers with 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 zone 2 and 22. These 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 are available in transparent, yellow, red, blue and green colours and the main body is made of strong synthetic materials. They withstand high pressure and heat as well as damage caused by acid or bases.

The signal towers have IP65 certification. 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 is IP54 certified.

Large product spectrum

Explosion-proof products that are suitable for Zones 2 and 22 also include the LKEH hybrid type model, EWH signal horns and CLA, CLK and CLN series LED working lights.

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