Explosion-proof light fixtures [Ex / ATEX - Zone 21, 22, 2]
HARDO explosion-proof light fixtures are designed for use in Zones 21, 22, and 2, where there is a risk of explosion due to flammable dusts or gases. They are widely used in the chemical, petrochemical, energy, wood, and food industries, but also in other sectors where safety, durability, and compliance with ATEX and IECEx standards are a priority. Their robust construction performs well in tough working conditions, ensuring high resistance to chemicals, mechanical damage, and adverse atmospheric conditions.
Advantages of OptiLine Ex ATEX HARDO Explosion-Proof Light Fixtures
The key advantage of HARDO light fixtures is their modularity and ease of installation, which translates into reduced installation time and costs. The light fixtures have through-wiring and the ability to connect without the need for junction boxes, minimizing the use of cables and installation materials. Moreover, thanks to the use of hinges, the lens and LED module do not fall during installation, which increases the safety of the installation.

Types and Features of OptiLine Ex ATEX Explosion-Proof light fixtures
HARDO offers Ex OptiLine explosion-proof lighting light fixtures that can be used as primary or emergency lighting. These are models equipped with high-performance LED modules, whose body is made of fiberglass-reinforced polyester (GRP), while the lens is made of UV-stabilized polycarbonate. These light fixtures offer a variety of lenses (transparent, frosted, milky) and the possibility of using lenses to direct light, facilitating the illumination of key areas without risking blinding employees.
Why Use Explosion-Proof light fixtures
Explosion-proof light fixtures are a key element of infrastructure in places where there is a risk of explosion due to flammable gases, vapors, mists of flammable liquids, or dusts. Their design and construction must meet the rigorous requirements of ATEX and IECEx certification, ensuring safety and reliability in extreme conditions. Among the models available on the market, light fixtures offered by HARDO stand out for their advanced technology and thoughtful design, adapted to demanding working conditions in explosion-prone Zones.
Explosion Hazard Zones and Explosion-Proof light fixtures
Zones 21, 22, and 2, for which explosion-proof light fixtures are intended, are defined based on the frequency of occurrence and duration of the explosive atmosphere. Zone 21 is an area where an explosive atmosphere in the form of dust is likely to occur during normal operation. Zone 22 is an area where the occurrence of an explosive atmosphere in the form of dust is possible but rare or short-lived. Meanwhile, Zone 2 refers to places where an explosive atmosphere in the form of gases, vapors, or mists may occur, but only rarely and for a short time. The selection and installation of explosion-proof light fixtures must take into account the specifics of these Zones to ensure maximum safety of use.
Requirements for Explosion-Proof light fixtures
To ensure safety and compliance with regulations, explosion-proof light fixtures must undergo a series of tests and certifications before being allowed for use. ATEX and IECEx certification is crucial for products intended for explosion-prone Zones and includes a comprehensive evaluation of design, materials, and manufacturing technology. These light fixtures are usually marked with the special Ex symbol, which is an international sign of safety, indicating their suitability for use in explosion-prone areas. Manufacturers must also provide detailed instructions for the safe installation, operation, and maintenance of such equipment. Additionally, these light fixtures are often equipped with additional safety features that prevent the occurrence of ignition sources in the light fixture, including overheated surfaces and electrical sparks. Safe and efficient lighting in Ex/ATEX Zones is not only a legal requirement but primarily a key element in ensuring the protection of life and health of workers and property protection.
What is an Explosive Atmosphere
An explosive atmosphere is a mixture of air with flammable substances in the form of gases, vapors, mists, or dusts, in which, after ignition, flame spread may occur. These light fixtures comply with the ATEX directive, meaning they meet the rigorous standards of the European Union for the use of equipment in potentially explosive atmospheres. Their construction must exclude any sparking, overheating, and other potential sources of ignition. This means that these light fixtures must be made from materials with high resistance to mechanical damage and corrosion.
