For corrosive environments, lighting with a stainless steel or high-quality plastic housing, combined with a high IP protection rating (minimum IP66), is the most suitable choice. Standard aluminum fixtures degrade quickly due to aggressive chemicals, sea air, or humid vapors, making them unsafe and leading to high maintenance costs. This article answers the most frequently asked questions about choosing the right lighting for corrosive industrial environments.<\/p>\n\n\n\n
Not every space with a bit of moisture or dust is immediately a problem, but as soon as substances are present that actively affect the housing, seals, or electrical components of a fixture, it becomes a different story. Consider saltwater, acids, alkalis, ammonia, chlorine, or a combination of moisture and chemical vapors. The more aggressive the substance and the longer the exposure, the faster standard fixtures will fail.<\/p>\n\n\n\n
In practice, the most corrosive industrial environments are found in sectors such as the chemical industry, paper industry, food processing companies, offshore platforms, harbors, and waste management. However, even within steel mills and recycling companies, aggressive fumes and dust particles can have a devastating effect on lighting installations.<\/p>\n\n\n\n
What many people underestimate: the damage caused by corrosion is not always visible from the outside. Internal oxidation of wiring and connections leads to malfunctions, short circuits, and ultimately fire hazards. Corrosion thereby not only undermines the lifespan of the fixture, but also the safety of the work environment.<\/p>\n\n\n\n
Stainless steel (SS) and specially formulated technical plastic are the most corrosion-resistant materials for industrial pipe fittings. Stainless steel offers excellent resistance to acids, alkalis, and saltwater, while high-performance plastics like polycarbonate or fiberglass-reinforced polyester can withstand a broad spectrum of chemicals without oxidizing.<\/p>\n\n\n\n
Aluminum is widely used in standard industrial lighting due to its low weight and good heat dissipation. However, in corrosive environments, untreated aluminum is vulnerable. Only with a special powder coating or anodization does it offer some protection, but in the most aggressive environments, that is simply not enough.<\/p>\n\n\n\n
When choosing materials, seals also play a crucial role. Silicone gaskets and seals based on EPDM rubber are resistant to extreme temperatures and a wide range of chemicals. Neoprene or standard rubber degrades much faster and leads to moisture ingress.<\/p>\n\n\n\n
For the toughest applications, such as lighting in the chemical industry or offshore, stainless steel lighting<\/a> with an integrated seal and corrosion-resistant fasteners the standard.<\/p>\n\n\n\n The IP protection class (Ingress Protection) indicates the extent to which a fixture is protected against dust and water. In corrosive environments, a minimum of IP66 is required, meaning the fixture is completely dust-tight and resistant to powerful water jets. For immersion or permanent exposure to liquids, IP67 or higher applies.<\/p>\n\n\n\n The two numbers in an IP class represent:<\/p>\n\n\n\n In practice, IP66 is the minimum for outdoor industrial lighting and areas where high-pressure cleaners are used. IP69K is the highest rating and is intended for fixtures that are regularly cleaned with hot, high-pressure water, such as in the food industry or in livestock farming.<\/p>\n\n\n\n One misunderstanding recurs regularly: a high IP rating does not automatically mean a fixture is corrosion-resistant. IP says something about the density, but not about the chemical resistance of the material itself. A fixture with IP66 in an aluminum housing can still degrade quickly in a chemically aggressive environment. For more background on IP ratings, consult the explanation of IP and IK ratings<\/a>.<\/p>\n\n\n\n ATEX certification is mandatory when lighting is used in environments where explosive atmospheres may arise due to the presence of flammable gases, vapors, mists, or dust. This is European legislation (Directive 2014\/34\/EU) and applies to zones classified as having an explosion risk by the employer.<\/p>\n\n\n\n The ATEX zoning determines which type of certified fixture is required:<\/p>\n\n\n\n In the chemical industry, petrochemicals, paint production, flour processing, and offshore, ATEX zones are standard. Using non-certified lighting in these zones is not only dangerous but also punishable. ATEX luminaires are often also designed to be corrosion-resistant, as the conditions in explosion-hazardous zones are typically also chemically aggressive.<\/p>\n\n\n\n For environments that are both explosion-hazardous and corrosive, such as chemical terminals or offshore platforms, it is essential that a luminaire meets both requirements. Offshore and maritime environments<\/a> represent the highest combined requirements.<\/p>\n\n\n\n The right choice is made based on four factors: the nature of the corrosive substance, the intensity and frequency of exposure, the presence of explosion hazards, and operational conditions such as temperature and cleaning method. No two corrosive environments are identical, so a tailor-made approach is necessary.<\/p>\n\n\n\n When making your selection, ask yourself the following questions:<\/p>\n\n\n\n Based on the answers, you can determine the material choice, IP class, and any ATEX category. Ports and terminals, where saltwater and chemical cargo meet, have different requirements than an indoor chemical storage area. View the solutions for lighting in harbors and terminals<\/a> as an example of how environmental requirements are translated into concrete lighting choices.<\/p>\n\n\n\n Don't forget to factor in maintenance costs. A cheaper fixture that needs to be replaced annually will be more expensive in the long run than a robust stainless steel fixture with a lifespan of ten years or more. Furthermore, LED technology significantly reduces energy consumption compared to conventional light sources, which is quickly recouped in 24\/7 operations.<\/p>\n\n\n\n A good example of how theory and practice come together is the project at DFDS, a large European ferry and logistics terminal. The challenge was multifaceted: the location is permanently exposed to sea air with high salt concentrations, intensive cleaning operations take place with high-pressure washers, and the lighting must function reliably in both low winter temperatures and warmer periods.<\/p>\n\n\n\n The design choice was for stainless steel fixtures with an IP66 rating, specifically selected for their resistance to chlorides and mechanical stress. A key operational constraint was the limited downtime: the terminal operates almost continuously, meaning maintenance is only possible during short, scheduled windows. This made long service life and low maintenance frequency non-negotiable requirements, not just desirable options.<\/p>\n\n\n\n The key lesson that directly follows the topic of this article: material certification and IP rating are just the starting point. The actual performance is determined by the combination of housing material, seal quality, and how the fixture is mounted and managed. An incorrect mounting position or a damaged gasket makes even the best IP69K fixture vulnerable.
