Vitzro Tech

What Vitzro Tech does

Vitzro Tech Co., Ltd. is the publicly-listed (KOSDAQ) South Korean holding company of VITZRO Group, founded in 1955 and headquartered in Seoul. Through six wholly-owned operating subsidiaries—VITZRO Electric, VITZRO EM, VITZRO ES, VITZRO VM, VITZRO Nextech, VITZRO Cell, and VITZRO Miltech—the group operates as a "Total Smart Energy" platform spanning power equipment, semiconductor vacuum components, lithium batteries, military thermal batteries, aerospace, and nuclear fusion systems.

The group's core technology base includes the first domestically developed vacuum interrupter (1981), localized thermal batteries for military missile systems (in collaboration with the National Defense Scientific Research Lab), Korea's first liquid rocket engine manufacturing capability, linear particle accelerator technology (proton, heavy ion, light), and lithium thionyl chloride battery manufacturing in which it holds the world's #3 position and a top domestic market share across the US, India, and Italy. Other core products include 170kV-class SF6-free ultra-high voltage vacuum circuit breakers, semiconductor vacuum valves with 30% domestic market share, ITER and KSTAR nuclear fusion components, and core subsystems for the KSLV-II Nuri launch vehicle.

The business model is B2B enterprise sales of industrial hardware. Revenue is generated through direct sales and contracts with utilities (KEPCO, Korea Hydro & Nuclear Power), defense agencies, semiconductor manufacturers, and international research consortia (ITER, KSTAR, KARI). Commercial channels are quote-based project bidding and long-term framework agreements with key customers; lithium primary batteries are sold via export to 250+ customers across 50+ countries with 80% of that segment's revenue coming from international markets. Government anchor contracts (ITER 190B KRW vertical stabilization coil, National Fusion Research Institute 240B KRW energy storage) and a recurring export award history ($50M/$70M/$100M Export Tower) point to a project-driven, infrastructure-tied revenue stream rather than a high-frequency transactional model.
