Nabertherm

What Nabertherm does

Nabertherm GmbH, headquartered in Lilienthal, Germany, and operating since 1947/1948, manufactures industrial, laboratory, dental, and arts & crafts kilns and furnaces spanning 850°C to 1800°C. Its product architecture uses multiple heating technologies — wire heating, SiC rod heating, molybdenum disilicide elements for the highest temperatures, and gas-fired high-speed burners with recuperator systems — packaged in standardized formats (chamber, top hat, bottom loading, bogie hearth, tube, retort) plus customized thermal process systems with integrated material handling and charging. Proprietary elements include DB100/DB200 debinding safety packages (catalytic or thermal exhaust post-combustion), five-sided heating with ±5°C uniformity per DIN 17052-1, and the Series 500 controller family (B500, C540, P570/P580, D580) with Wi-Fi connectivity and the MyNabertherm mobile app for remote monitoring and program management.

Revenue mechanics come primarily from hardware sales of standard furnaces and customized thermal systems, complemented by aftermarket spare parts and service. Nabertherm operates a direct field-sales model through wholly-owned subsidiaries in the UK, China (纳博热), and Japan (ナーベルザーム), plus regional sales representatives and a separate dealer network for Arts & Crafts products. Pricing is quote-based and not publicly disclosed. The company serves five primary segments — Industry/Advanced Materials, Industrial Heat Treatment, Laboratory, Dental, and Arts & Crafts — with adjacent exposure to Additive Manufacturing and university research. Named industrial customers include the University of Paderborn and Phi-Stone AG (pharmaceuticals); in dental, Nabertherm holds validated material programs with Ivoclar Vivadent AG, Vita Zahnfabrik, Dentsply Sirona, Amann Girrbach, and GC. The company is DIN EN ISO 9001 certified, claims 150,000+ satisfied customers worldwide, and is led by Managing Director Timm Grotheer, with Conrad Naber recorded as founder.
