Explosion proof linear LEDs are engineered for safety‑critical areas where vapors, gases, or dust can be present—onshore, offshore, or indoors. Use them wherever consistent, low‑glare light, reliable sealing, and verified certification are mandatory for operations and compliance.
Oil & Gas: catwalks, separators, compressor rooms, blending, loading racks
Chemical & Petrochemical: process corridors, tank farms, mixing areas
Marine & Offshore: platforms, pump rooms, stairwells, docks, shipyards
Paint/Coatings & Manufacturing: booths, prep bays, production lines
Food/Ag & Milling (Dust): grain handling, feed mills, packaging lines
Utilities & Water/Wastewater: galleries, tunnels, treatment buildings
Selection depends on your hazard class/division and environmental realities (corrosion, washdown, impact). Confirm the exact listing per model and configuration before specifying:
UL844 Hazardous Locations (Class 1/2 Div 1/2—verify Group A–G as required)
UL 1598A Marine (select models) for ship/offshore use and wet locations
ATEX / IECEx (EXI variants) for international explosive atmospheres
NEMA 4X / IP66–IP67 sealing against water, dust, and corrosion
Optical & Electrical: beam distributions, driver ranges, emergency options
Class 1 Division 1 areas have ignitable gases or vapors present during normal operation or frequently, so fixtures must be rated to contain ignition. Class 1 Division 2 areas handle flammable gases or vapors but they are normally confined and only present under abnormal conditions such as leaks or equipment failures. For Class 1 Division 1 applications, models like IR4 and EXI are recommended. For Class 1 Division 2, models such as IR3, IR7, and IR1 are suitable depending on the lumen and output requirements. The EXH model is primarily used for dust (Class 2 Division 1) but also covers Class 1 Division 2.
Yes, all models including EXI, IR1, IR3, IR4, IR7, and EXH support common mounting methods. The IR1 fixture is most often surface-mounted in wet or marine locations. The IR7 model is well suited for chain or surface mounting, making it popular in process bays, while the IR3 includes swivel brackets that allow precise aiming. Always confirm clearance and conduit routing based on your site requirements.
Yes, several models are designed to operate in marine and wet environments. The IR1 is specifically built for wet and outdoor marine applications with a non-metallic, corrosion-resistant fiberglass housing and gasketted sealing. The IR3 is marine-rated (UL 1598A) and includes additional corrosion protection. The EXI and EXH models also offer enclosures and finishes that are suitable for wet or corrosive conditions. For highly demanding environments, it is always recommended to confirm salt-fog and corrosion requirements with your MAES representative.
