Abtech have extended capability of the Gamma range of LED luminaires with Ex-certification for Zone 1 hazardous areas. Suitable for use both in gas and dust environments, the Gamma range has been designed with consideration for the rigours of operational oil and gas production. The complete range is both ATEX and IECEx certified.
The Zone 1 Gamma is initially available as 72W intrinsically safe luminaire that provides around 10,000 lumens of crisp white light. It is equally at home when installed as a traditional floodlight or suspended to act as a lowbay luminaire. Abtech’s innovative approach to LED development combined with the release of our own iSMART driver technology give the Gamma several design advantages.
Firstly, certification was achieved without the need for heavy Ex d enclosures. These are commonly used by luminaire manufactures as a method of isolating unprotected LEDs from exposure to potentially explosive gasses. Not only does this make the Gamma relatively lightweight but it also removes the need for annual inspection of any exposed flamepath, thus reducing lifetime maintenance costs. Secondly thanks to Abtech’s iSMART driver technology with built in fail safe mechanisms to prevent sparking, there is no requirement to encapsulate the LED’s. Even the best clear encapsulates result in light loss due to internal refraction. Some have been known to become cloudy over time, particularly when exposed to complex hydrocarbon compounds associated with oil & gas production. As the Gamma does not require encapsulation, transfer of the light generated is maximized resulting in a very efficient 138lm/w and no reduction in lumen maintenance through encapsulate degradation.
In line with its Zone 2 counterpart, the new Zone 1 version is constructed from marine grade stainless steel with a toughened glass diffuser, stainless steel fixings throughout. It is designed to operate within an ambient range of -30°C to +55°C (T3/T4) ensuring the luminaire can withstand the harshest of environments.
All Gamma variants incorporate harmonic and overvoltage protection to EN61000-3-2 & EN61000-3-3. The control gear also features thermal cut off protection to maintain LED life. All Gamma luminaires are tested at an operational ambient of 40°C and supplied with a five-year complete system warranty.
