What SETA does

Servicios Técnicos SETA S.L. is a privately held Spanish industrial services company that installs, commissions, maintains, repairs, and supplies consumables for water treatment equipment. Founded around 2000 and headquartered in Madrid, the firm serves industrial and municipal customers across Spain, with a portfolio that includes reverse osmosis, ultrafiltration, demineralization, desalination, electrodeionization, UV disinfection, and filtration systems. The company holds ISO 9001:2015 certification and operates as an authorized technical service center for multiple global OEMs, including Atlantium Technologies (HOD UV systems), Asahi Kasei (MICROZA ultrafiltration membranes), and B. Braun (pharmaceutical water plants), giving it access to proprietary technologies and direct manufacturer warranty channels.

The core technology stack spans seven water treatment modalities, supported by a proprietary membrane regeneration service that extends reverse osmosis membrane life by at least 50% and reduces replacement costs by up to 60%. SETA also offers laboratory demineralizers (R/RR and BL series), industrial filtration systems, water softening units, and SCADA-integrated remote plant monitoring. Named enterprise customers include Repsol, Bosch, L'Oréal, BASF, Cepsa, Iveco, Hoya Lens, Sesderma, and municipal clients such as Rivas Madrid, indicating a diversified enterprise customer base across energy, chemicals, consumer goods, and public-sector segments.

The business model combines recurring revenue from preventive and corrective maintenance contracts with transactional revenue from equipment supply, spare parts, chemicals (including its own SETACLEAN detergent line), filter media, demineralized water supply, and one-off professional services such as plant modernization and technical training. Go-to-market is sales-led, with customers reached through direct phone, WhatsApp, email, and a quote-based pricing model. SETA employs 51-100 people and operates only in Spain, with no disclosed funding, M&A, or geographic expansion activity in the available data.
