What Aichelin does

Aichelin Holding GmbH is a privately held Austrian industrial heat treatment technology company founded in 1868 and operating as a subsidiary of the Berndorf AG conglomerate. The Group designs, manufactures, and services industrial furnace systems — including batch furnaces (chamber, vacuum brazing, vacuum annealing, vacuum oil/gas quench), continuous furnaces (roller hearth, rotary hearth, pusher, ring hearth, mesh belt, cast plate band), and specialized battery-material processing furnaces — alongside burner technology (NOXMAT), endogas generation (EndoFlex), automation and controls (UPC-Marathon), and digital process software (FOCOS 4.0, #jakob maintenance app). The portfolio serves customers across automotive (primary segment), fasteners, steel and forging, aluminum, bearings, watch and precision parts, commercial heat treaters, energy/battery materials, aerospace, and medical technology, with installed equipment across more than 50 countries.

Revenue is generated through capital equipment sales (custom, project-based, multi-year contracts), spare parts (over 200,000 SKUs covering Aichelin and third-party systems), lifecycle services (maintenance, modernization, retrofit), and energy-efficiency analysis (Green Check). Distribution is direct-to-enterprise via wholly-owned subsidiaries across Austria, Germany, France, Slovenia, Turkey, Poland, the USA, China, and India, supplemented by regional channel partners (e.g., Arrola in Spain). The Group employs 1,350+ people globally and completed the acquisition of Nitrex Metal sp. z o.o. in October 2025, extending its surface-treatment technology portfolio. Recent strategic moves include a unified "One.AICHELIN worldwide" brand architecture (May 2026), a new India production facility and China headquarters (groundbreaking December 2025), and a dedicated battery heat treatment product line targeting the EV supply chain.
