Explosion proof lighting fixtures, also known as hazardous area ( location ) lighting fixtures, they are designed to be used safely in areas where there are explosive gases or combustible dust. The explosion-proof luminaires work to prevent the spread of internal possible arc, spark and high temperature to the surrounding explosive and flammable atmospheres to avoid explosions and ignitions. LED explosion proof lights provide a durable, powerful and energy efficient replacement for conventional hazardous area luminaires, they feature better thermal management and illumination performance, also they are robust and long lasting, low operation and maintenance cost.
A hazardous area can be defined as any location where explosive gases or combustible dust may exist in the air in quantities sufficient could produce explosions or ignitions, but every hazardous area is different and each has specific requirements based on the nature of atmosphere and the elements that are present.
Hazardous areas with Explosive Gas Atmospheres are classified into 3 zones, according to the frequency of the occurrence and duration of an explosive atmosphere as follows of ATEX / IECEx standards.
Area in which an explosive gas-air mixture is present continuously or for long period or frequently, more than 1000 hours / year.
Area in which an explosive gas-air mixture is likely to occur in normal operation occasionally, 10 to 1000 hours / year.
Area in which an explosive gas-air mixture is not likely to occur in normal operation but, if it does occur, will last for a short period, 1 to 10 hours / year.
Hazardous areas with Combustible Dust Atmospheres can be also defined into 3 zones.
Area in which a cloud of combustible dust is present continuously or for long period or frequently, more than 1000 hours / year. For example a mile or pneumatic conveying system.
Area in which a cloud of combustible dust is not likely to occur in normal operation but, if it does occur, will last for a short period, 1 to 10 hours / year. For example, bagging points and inspection parts that are frequently opened.
Area in which a cloud of combustible dust is not likely to occur in normal operation but, if it does occur, will last for a short period, 1 to 10 hours / year. For example, leaks from incorrectly fitted lids or spillages.
Zone system is for international, and in the USA there is another system called class/division system, zone 0 and zone 1 approx class 1 division 1, zone 2 approx class 1 division 2; zone 20 and zone 21 approx class 2 division 1, zone 22 approx class 2 division 2.
The most common hazardous areas are gas and petrol stations, marine loading terminals, chemical processing facilities, paper mills, printing factories, wastewater treatment plants, storage facilities, manufacturing plants, heavy industries, etc.
Special precautions should be taken in hazardous areas to prevent lighting fixtures from being sources of explosion and ignition.
Our Caneo Series is designed for using in gas stations and other hazardous areas of zone 1, zone 2, zone 21 and zone 22. Explosion proof performance and IP66 protection, solid built aluminum light body combined with excellent thermal management, delivering up to 130 lm/W. We manufacture hazardous area lights that provide safety, visibility and durability.
