Huber Kältemaschinenbau

What Huber Kältemaschinenbau does

Huber Kältemaschinenbau, headquartered in Offenburg, Germany, is a family-owned manufacturer founded in 1968 that builds high-precision temperature control equipment spanning roughly -125 °C to +425 °C. Its portfolio includes Unistat dynamic temperature control systems (using a sealed thermal circuit and UniBLOC modular architecture), Unichiller recirculation coolers — including models repositioned as the world's first natural-refrigerant chillers — bath and circulation thermostats, and the Piccolo Peltier compact unit. Application-engineered software (Pilot ONE controller) supports programmable profiles, data logging, and OPC-UA connectivity for Industry 4.0 integration, while E-grade Explore documentation targets regulated process-development environments.

The company sells direct and via wholly-owned subsidiaries in the USA, Switzerland, Italy, India, the UK, Ireland, France, and China, with active distribution in roughly 90 countries. End customers span pharmaceutical and chemical process development, academic and government research (e.g., CERN, DLR), automotive and e-mobility test stands (e.g., BMW), semiconductor equipment makers (e.g., Aixtron), and laboratory instrumentation manufacturers (e.g., Mettler Toledo). The recurring revenue layer is anchored by service, qualification documentation, and — increasingly — by F-Gas-driven replacement demand for natural-refrigerant platforms.

In 2023 the legal form was converted to a Societas Europaea (SE), in 2024 the Italian operation was rebranded Huber ITALIA, and in February 2025 the company completed the transition of its full portfolio to natural refrigerants ahead of tightening EU F-Gas Regulation phase-downs. The company has also built an acquisition track record (e.g., Van der Heijden Labortechnik in 2017) and has been recognized as a Top 100 Innovator and top employer in Germany.
