Atexor SLAM FIXED® WS Luminaires at Neste Refinery
Atexor Oy partnered with Neste Corporation to develop a custom ATEX certified LED lighting solution for their Porvoo and Naantali refineries — replacing aging fluorescent tubes with the purpose-built SLAM FIXED® WS luminaire family, improving energy efficiency, safety, and significantly reducing maintenance burden across Ex-classified hazardous areas.
The Challenge: Replacing Fluorescent Tubes in an ATEX Hazardous Area
Neste Corporation — one of Europe's largest refiners and the world's leading producer of renewable diesel made from waste and residues — operates complex refinery facilities at Porvoo and Naantali in Finland. In EX-classified hazardous areas, every detail matters and every risk must be eliminated.
Neste needed to replace its aging fluorescent tube lighting with a modern solution that would deliver improvements across three dimensions: occupational safety, maintenance cost, and environmental impact. The project required more than a standard product replacement — it demanded a custom-engineered lighting solution capable of performing reliably in harsh Nordic conditions, including extreme cold, while meeting the full ATEX classification requirements of the refinery's hazardous areas.
Why Neste Chose Atexor
- ✓Cost-effective, environmentally friendly LED technology
- ✓Established reputation for high quality and reliable delivery of Ex certified luminaires
- ✓Decades of experience in lighting EX-hazardous areas across complex industrial facilities
- ✓Ability to produce custom-made fittings and installation kits tailored to client requirements
- ✓Track record of solving hazardous area challenges within demanding project timescales
The Solution: Atexor SLAM FIXED® WS Luminaires
From the outset, it was clear that Neste required a joint development project rather than a standard catalogue product. Working closely with Neste's engineering team, Atexor developed the SLAM FIXED® WS product family — a market-leading fixed ATEX certified LED luminaire family designed specifically for the Neste refinery environment.
Two primary luminaire configurations were deployed:
SLAM FIXED® MZ2268
Single LED unit with pole fittings — for process area and pipe rack installations requiring pole or column mounting.
SLAM FIXED® MZ2271
Dual LED units with ceiling/wall fittings — for covered process areas, walkways, and understructure mounting positions.

“We carried out a comprehensive, long-term technical assessment on Atexor's products. We managed to test and solve several technical issues, and the outcome satisfies all our requirements.”
Results
The SLAM FIXED® WS installation at Neste's Porvoo and Naantali refineries delivered measurable improvements across all three original objectives:
- ✓Energy efficiency improved through modern high-output LED technology replacing fluorescent tubes
- ✓Occupational safety enhanced by bright, non-glare SafeEye® illumination in EX-classified process areas
- ✓Maintenance burden significantly reduced — long LED life cycle eliminates frequent bulb and tube replacements
- ✓Hazardous area compliance fully maintained — ATEX certified and IEC 60079-28 optical radiation compliant
- ✓Installation simplified by factory-mounted fittings, cables, and custom acid-proof steel kits
