Perinox

What Perinox does

Perinox (legal name PERINOX, S.A.) is a privately held, family-owned Spanish industrial engineering company headquartered in Villarrobledo, Albacete, founded in 1980 to manufacture stainless steel tanks and equipment for the wine and dairy industries. The company has evolved into a specialized provider of crossflow (tangential flow) membrane filtration systems, with core technologies spanning microfiltration, ultrafiltration, nanofiltration, and reverse osmosis, complemented by pasteurization units, CIP/SIP systems, and SCADA-based Industry 4.0 automation. Its proprietary whey protein microparticulation process, developed under the Castilla-La Mancha Business Innovation Support Program and used for fat-replacement applications, is a distinctive technology asset. Perinox delivers fully integrated turnkey engineering projects covering consulting, pilot plant development, custom equipment fabrication, installation, commissioning, and post-sale service, with documented outcomes such as 18%+ yield improvements in Quark and Tvorog cheese production. The company is ISO 9001:2015 certified by Bureau Veritas and operates from a single headquarters location with 11-50 employees.

The company serves enterprise customers across multiple industrial verticals — dairy and cheese processing (its primary segment), biotechnology (including plant-based bioprocessing), blood plasma and hemoderivatives, food and beverages, industrial water treatment, ultrapure water for electrolysis / green hydrogen (in collaboration with CENER), chemical recovery, and agriculture. International operations span Europe, the Americas (including Ecuador and Argentina), Africa, and the Middle East, following an expansion phase from 2000-2010. The business model is sales-led, direct-to-enterprise, with project-based custom pricing (no public price list), combining equipment sales, engineering services, pilot development, and recurring after-sales support. Marketing is conducted via multilingual website (Spanish, English, French) technical content, LinkedIn, and participation in industry events such as Food 4 Future Expo FoodTech and CDTI innovation meetings.

Recent commercial evidence includes multiple enterprise project launches in late 2025 and early 2026 — a fully automated ultrafiltration cheese line, a blood plasma filtration and concentration system, a plant-based biotechnology fluid treatment line, and an industrial water recovery system for a juice plant. The Managing Director, Ana Senabre Sánchez (widow of founder Juan José Torres Gómez), received the 2025 Business Merit Award from the Confederation of Business Owners of Albacete (FEDA), underscoring the company's regional recognition and continuity of family leadership. No funding rounds, acquisitions, or public-market activities are recorded; Perinox remains a privately held, founder-family-controlled operating company.
