Raci D.o.o.

What Raci D.o.o. does

RACI d.o.o. is a Slovenia-based, privately held engineering company founded in 1994 as a technology-transfer spinoff from the Jožefef Stefan Institute, specializing in energy-ecological engineering and continuous industrial emission monitoring. The company designs, supplies, installs, commissions, and maintains Automated Measuring Systems (AMS), Data Acquisition and Handling Systems (DAHS), and complete Continuous Emission Monitoring Systems (CEMS) for stationary pollution sources such as thermal power plants, district heating facilities, cement, glass, mineral wool, chemical, pharmaceutical, steel, paper, and waste incineration plants. RACI does not manufacture analyzers; it acts as a regional systems integrator combining FTIR, NDIR, paramagnetic, FID, dust, and flow equipment from global OEMs (Gasmet, Siemens, ENVEA/PCME, DURAG, Enotec, Bühler, MSA, Michell) into turn-key installations.

The company's revenue model blends one-time equipment sales and integration project revenue with recurring maintenance, calibration, and accredited inspection services. It operates two accredited bodies — Testing Laboratory LP-076 (SIST EN ISO/IEC 17025) and Inspection Body K-085 (SIST EN ISO/IEC 17020 type C) — and holds authorizations from the Slovenian Ministry of the Environment, Climate and Energy and the Croatian Ministry of Economy and Sustainable Development to perform legally binding emission operational monitoring and QAL2/AST inspections per SIST EN 14181. Pricing is quote-based and project-specific, with sales executed through direct enterprise engagement with customer engineering and environmental departments.

RACI serves more than 100 reference clients across 35+ countries, anchored by long-term relationships with repeat enterprise customers such as Knauf Insulation, Holcim, JP Energetika Ljubljana and Maribor, Termoelektrarna Šoštanj, Lek, SIJ Acroni, Cinkarna Celje, and Papirnica Vevče. The company holds exclusive regional distribution rights for Gasmet Technologies across Slovenia, Croatia, and the Western Balkans, and is a Siemens Solution Partner for Process Analytics since 2013. It is headquartered within the Ljubljana Technology Park and has held the Excellent SME Slovenia certificate from the Chamber of Commerce and Industry of Slovenia for ten consecutive years.
