RENI

What RENI does

RENI d.o.o. is a privately held Slovenian process engineering company that designs and manufactures custom stainless steel process equipment for pharmaceutical, biopharmaceutical, and food industry clients. Its portfolio spans CIP/SIP systems, purified water (PW) units, mobile mixing vessels and pressure duplicators, pasteurizers, fermentation units, dosing and weighing systems, valve manifolds, and SKID-mounted process modules, with the FERMI SKID BF50 bioreactor (launched 2024) extending coverage into bacteriophage production for biopharma. Equipment is built around 3D-modeled mechanical design, in-house automation and SCADA visualization, GAMP 5 compliant control software, and certified fabrication (ASME BPE, PED, EN ISO 3834-2, EN 1090-1, ATEX) executed across engineering and workshop facilities in Ljubljana and a production unit in Bosanska Krupa, Bosnia and Herzegovina. The company offers end-to-end delivery from conceptual design through installation and DQ/IQ/OQ qualification, plus recurring maintenance and spare parts, and supports clients through additional offices in Machelen (Belgium) and a representative office in Algiers (Algeria).

RENI sells primarily through direct enterprise B2B engagement with engineering and commercial teams via phone and email, executing project-based turn-key contracts rather than catalog sales. Its customer base includes pharmaceutical majors such as Krka, Lek, Pfizer, Novartis, GSK, MSD, Sanofi (Dr. Niedermaier / SANUMTEC), and Hemofarm; biopharma customers including Univercells, BioWin, Eurogentec, and Medace; and food and beverage clients such as Heineken, Atlantic Grupa, Radenska, Ljubljanske mlekarne, Mlekarna Celeia, Argeta, Cockta, and EMPWR. Pricing is quote-based and not publicly disclosed. The company reports 50+ employees across engineering, assembly, automation, production, and commercial functions, and states it has completed 300+ projects across 11 countries over 20+ years.
