What Klimaoprema does

Klimaoprema d.o.o., headquartered in Samobor, Croatia, designs and manufactures HVAC, air-conditioning, and cleanroom equipment for regulated industrial customers. Founded in 1975 and operating as part of the Amelicor Group, the company is organized into five divisions — Cleanroom Solutions (engineering, design, production, assembly, service, balancing, and validation of cleanrooms), HVAC Solutions (fire dampers, VAV/CAV dampers, air distribution, filtration, sound attenuation, air handling units, and kitchen ventilation), CQV Solutions (commissioning, qualification, validation, and calibration services), Electronic Solutions under the KOER brand (predictive building energy management using model predictive control), and Microelectronic Solutions (the German subsidiary MCRT acquired in 2021). The company operates an in-house EN 12238 testing laboratory and an ISO/IEC 17025 calibration laboratory supporting its validation services.

The business model is enterprise project-based: turnkey delivery combining engineering, manufacturing, installation, and validation under single-source responsibility, with multi-year preventive maintenance contracts providing a recurring revenue layer. Pricing is custom per project, with no public list pricing, and go-to-market is direct enterprise field sales targeting pharmaceutical manufacturers, hospitals, and industrial clients across Croatia, Hungary, Slovenia, Germany, and other European markets. Customer evidence includes named pharmaceutical accounts (JGL Pharma Valley, Belupo, Apipharma, Tallinna Farmaatsiatehase AS), healthcare accounts (KBC Split, Specijalna bolnica Sveta Katarina), and industrial/niche applications (CEVA Logistics, the Kanuni drillship, Emerald Azzurra yacht). Klimaoprema holds ISO 9001, 14001, 45001, 13485, 50001, and 17025 certifications, has earned an EcoVadis Bronze sustainability rating, and publishes Environmental Product Declarations and Revit BIM families to support specifier integration. Revenue is not publicly disclosed; the company is privately held with no disclosed funding rounds.
