Me-Sep

What Me-Sep does

Me-Sep Sp. z o.o. is a Polish B2B engineering company founded in 2018 and incorporated in 2021, headquartered in Kraków with a manufacturing facility in Ściejowice. The company designs, manufactures, and supports specialized equipment and services for membrane technology, with a focus on hollow fiber and flat sheet membrane production, module manufacturing, and the construction of separation systems for gas and liquid mixtures. Its customers are industrial membrane manufacturers, research institutions, and universities, with downstream application verticals spanning medical and life sciences (dialysis, dialyzers), food and beverage processing, water and wastewater treatment, and environmental/energy applications including gas separation, CO2 capture, and direct air capture.

The product platform is organized into membrane manufacturing equipment (hollow fiber spinning machines, MemCast automated casting systems, rinsing stations, fiber dryers, bundle preparation machines, spinnerets), module manufacturing equipment (Midi, Pilot, Pro, and Rota-Me series potting centrifuges, Me-Mix resin dosing systems, Me-Cut guillotines, integrity testers), performance evaluation equipment (membrane testing systems, testing cells, microscopes), custom design and contract manufacturing (CAD design, prototyping, pilot plants, small-batch production in polymers and stainless steel), and research/consultancy and characterization services. The company also acts as official Polish/international distributor for five third-party membrane equipment brands: Porometer, MEMS, Luxor, MemSystems, and Demcon Convergence.

Me-Sep operates a direct enterprise sales model with custom, quote-based pricing on multi-year engagements. Revenue is generated through one-time equipment sales, contract manufacturing of small-batch modules, professional services (consultancy, process optimization, characterization), and hardware resale through distribution agreements. The company is privately held by its two PhD-credentialed founders from the University of Twente, has grown to 20 employees as of 2023, and supplements commercial activity with non-dilutive EU and Polish grant funding (NCBR, EIC, BMBF) for R&D projects in advanced membrane applications.
