Fivemasa

What Fivemasa does

Fivemasa S.L.U. is a Spanish industrial engineering company headquartered in Bilbao that designs, manufactures, installs, and services custom air pollution control and gas filtration equipment for heavy industry. Founded around 1980–1985 and operating as the dedicated emissions control subsidiary of Grupo Nervión (Nervion Industries) — itself now majority-owned by Frankfurt-listed turnaround investor MUTARES as of March 2025 — Fivemasa sells turnkey projects to enterprise clients in sectors including ferrous and non-ferrous foundry, steel, cement, glass, biomass energy, petrochemical, waste-to-energy, and food/pharmaceutical processing. The company presents itself as a one-stop shop covering design, engineering, manufacturing, assembly, commissioning, and aftermarket maintenance.

The company operates an eight-category product portfolio: air pollution control systems (FIVEPULSE bag filters, FIVECERAMIC ceramic filters rated to 900°C, FIVECARTRIDGE cartridge filters, electrofilters with spiked ionisers, cyclones, venturi and spray scrubbers, dry and semi-dry absorption, regenerative thermal oxidizers with 99%+ destruction efficiency, SCR with >95% NOx reduction and SNCR systems), noise control, centralized vacuum cleaning, pneumatic conveying, centrifugal fans, grinding and classification mills, flash drying, and incineration/cremation equipment. Performance is benchmarked quantitatively (RTO 99–99.5% destruction, SCR >95% NOx, incinerator 95% volume/weight reduction, 2-second gas residence).

Commercially, Fivemasa runs a direct enterprise field sales motion with custom project-based pricing. Revenue is generated through capital equipment sales (one-time project revenue) plus recurring maintenance, spare parts, retrofits, and consulting services. Customers include Cepsa, ARC International, and operators in steel, biomass, copper recycling, and ferroalloy sectors. The geographic footprint covers Spain, Portugal, France, and Venezuela, with no public revenue disclosure or AI/ML capability claims.

Direct peers

• CECO Environmental Corp: US-based pure-play industrial air-pollution-control and engineered solutions provider serving similar heavy-industry verticals (metals, cement, power, waste). Direct one-stop-shop competitor to Fivemasa with comparable bag-filter, ESP, scrubber, and aftermarket service model.
• Hamon & Cie (Hamon Group): Belgian industrial group specializing in cooling systems and air-pollution-control equipment for power and process industries. Closest European competitor with overlapping dust collection, flue-gas treatment, and emissions-control product portfolios.
• BWF Envirotec (BWF Group): German filtration-media and dust-collection specialist supplying bags, cages, and complete filter systems for industrial gas streams. Direct comparable in the bag-filter and dust-collection segment that anchors Fivemasa's FIVEPULSE offering.

Broad incumbents

• Babcock & Wilcox Enterprises: Large US-headquartered incumbent in industrial steam generation and emissions-control technology. Competes with Fivemasa on flue-gas treatment, particulate control, and waste-to-energy abatement, but as part of a broader power-systems portfolio.
• FLSmidth & Co. A/S: Danish global supplier of equipment and services to cement, minerals, and metals processing. Competes with Fivemasa's filtration and pneumatic-conveying products in cement and minerals but as part of a much broader process-plant portfolio.
• Thermax Limited: Indian industrial conglomerate with a dedicated EPC business in air-pollution control, waste-heat recovery, and incineration. Direct overlap with Fivemasa's RTO, ESP, and incineration offerings across cement, steel, and waste-to-energy customers.
• Dürr AG: German industrial-engineering incumbent with a Clean Technology Systems division offering exhaust-air purification and VOC abatement. Overlaps Fivemasa in RTO and industrial air-treatment but operates across automotive paint, woodworking, and process industries.
• ANDRITZ AG: Austrian industrial-equipment group serving pulp, paper, metals, and energy with air-pollution-control and drying technology. Comparable to Fivemasa's flash-drying and gas-cleaning lines but at significantly larger scale and geographic reach.
• Atlas Copco AB: Swedish global industrial-equipment leader with vacuum, blower, and compressor product lines. Overlaps Fivemasa's pneumatic-conveying blower systems and industrial-fan offerings as part of a vastly larger compressor-and-vacuum portfolio.

Emerging players
