- Vitzro Nextech Co., Ltd. is a South Korea-based engineering and manufacturing company specializing in advanced aerospace propulsion, nuclear fusion systems, particle accelerator components, and plasma-based environmental solutions. Founded in August 2016 through a physical spin-off from Vitzro Tech Co., Ltd. and headquartered in Ansan, Gyeonggi-do, South Korea, the company utilizes ultra-precision vacuum brazing and advanced heterogeneous material bonding technologies to deliver high-performance equipment for aerospace, defense, scientific research, and high-tech industrial markets. The company operates through four core business segments: Aerospace, Nuclear Fusion, Particle Accelerators, and Plasma & Environmental Systems. Its comprehensive product and service portfolio includes liquid rocket engine assemblies and components, such as regenerative cooling combustors, gas generators, turbopump manifolds, injectors, and propulsion test facilities; nuclear fusion reactor components, including tungsten divertors, plasma-facing units, first wall protection panels, neutral beam injection heating systems, and vertical stabilization coils for international and domestic fusion projects such as ITER and KSTAR; particle accelerator infrastructure, comprising RF accelerating cavities, vacuum chambers, waveguide transport systems, and high-power radio-frequency sources; and environmental plasma systems, including high-temperature plasma torches, radioactive waste volume reduction furnaces, and organic waste gasification plants. The company primarily caters to government research institutes, space agencies, national laboratory facilities, aerospace prime contractors, and industrial clients across South Korea, Asia, Europe, and North America. Recent major corporate developments include the completion of its initial public offering on the KOSDAQ exchange in November 2025 under ticker 488900; securing a series of high-profile aerospace contracts in 2026, including an agreement with Hanwha Aerospace to supply high-pressure combustors for next-generation launch vehicles, a detailed engineering design contract with the Korea Aerospace Research Institute for next-generation methane engine combustion test facilities, and a contract for the supply of an integrated wind tunnel testing apparatus; achieving successful domestic performance certification for its independently developed 80-megawatt S-band klystron at the Pohang Accelerator Laboratory (PAL-XFEL); and broadening its international footprint through a multi-year supply contract with a Japanese semiconductor substrate manufacturer.
