Ramson

What Ramson does

Ramson AB is a Swedish industrial filtration company founded in 1964 and headquartered in Motala, Sweden. The company designs, manufactures, and services filtration systems for liquids and gases used in industrial processes, with a core product line of PLC-controlled self-cleaning automatic filters (models 41-02, 41-03, 41-04), basket strainers, cartridge filters, and bag filters. Building on this installed base, Ramson has expanded into membrane filtration (UF, NF, RO) through a partnership with Veolia Water Technologies & Solutions, specialized PFAS/PFOS removal systems, UV disinfection, self-cleaning wastewater heat exchangers (Bauer Spuab), and pressure vessels, all certified to ISO 9001, ISO 14001, and ISO 3834-2 standards and approved for nuclear-power supply.

The company serves two principal customer segments: industrial manufacturers across mining, steel, power, electronics, paper, chemicals, shipping, pharmaceutical, and food industries; and municipal water utilities, which have grown to approximately 40% of revenue since 2015. Its go-to-market is direct enterprise field sales with regional account managers across Sweden, Denmark, Norway, Finland, and Germany, supported by trade show presence (Vatten2025, Underhåll 2026, Malmö Nordic Industry Fair), a content-rich website, and an in-house team of filter chemists who run pilot tests and on-site filtration analyses.

Ramson generates revenue across five streams: filtration hardware sales (its core offering), recurring consumables (filter bags, cartridges, seal kits) with 1-2 day delivery from a central warehouse, on-site and workshop service and annual maintenance, an equipment rental fleet of approximately 30 filters for pilot and temporary needs, and full turnkey water treatment solutions — including container-based systems — sold under purchase, rental, hire-purchase, or per-cubic-meter pricing models. In March 2025, Uniwater signed an agreement to acquire Ramson (expected close Q2 2025), positioning the company within a larger Nordic water-infrastructure platform.
