What Marioff does
Marioff Corporation, headquartered in Vantaa, Finland, designs, manufactures, installs, and services the HI-FOG® line of high-pressure water mist fire suppression systems. Founded in 1985, the company is positioned as a pioneer in water mist fire protection, with technology that suppresses fires through cooling combustion gases, displacing oxygen, and wetting fuel, while using significantly less water than conventional sprinkler systems. The product portfolio is split across two core verticals: marine (cargo ships, cruise ships, ferries, naval vessels, offshore platforms, and yachts) and land-based applications (data centers, hospitals, hotels, automotive plants, power generation, food industry, cultural heritage sites, and battery energy storage systems), with system components and a dedicated IoT monitoring add-on introduced in 2025.
Marioff generates revenue through two streams: one-time sales of engineered fire suppression systems via direct enterprise field sales, and recurring lifecycle services covering installation, maintenance, and ongoing support across the system lifespan. Pricing is quote-based and not publicly disclosed, reflecting the custom-engineered nature of each deployment. The company holds type approvals from major classification and testing bodies including DNVGL, ABS, Lloyd's Register, FM Approvals, VdS, and complies with IMO, NFPA 750, and EN 14972 standards, with active installations in more than 70 countries and roughly 650 employees globally.
Marioff is privately held, having been acquired by Inflexion Private Equity Partners in mid-2026 (EU cleared June 2026) from Sentinel Capital Partners, which had itself acquired the business from Carrier Global Corporation's industrial fire unit in 2024. The Inflexion partnership is explicitly oriented toward accelerating land-based market growth while preserving the marine customer base and expanding aftermarket service revenue. Reported revenue in the latest disclosed financial year was $266 million USD.
