Business
HanSun Engineering Co., Ltd. is a South Korea-based manufacturer specializing in instrumentation fittings, industrial valves, and fluid control piping solutions for clean energy, semiconductor, petrochemical, shipbuilding, and power generation industries. Founded in 2012 and headquartered in Busan, South Korea, the company operates as an affiliate of Hankook Sunjae Co., Ltd. HanSun Engineering designs, engineers, and markets fluid and gas management components primarily under its proprietary S-LOK brand. The company's core product portfolio encompasses instrumentation fittings, including double ferrule tube fittings, bite type DIN 2353 fittings, 37-degree flare fittings, precision pipe fittings, push-on hose fittings, and high-pressure weld fittings; instrumentation and process valves, comprising ball valves, needle valves, manifold valves, check valves, bleed and purge valves, gauge root valves, safety relief valves, and double block and bleed (DBB) valves; ultra-high purity (UHP) components, including semiconductor-grade clean fittings, diaphragm valves, and electropolished tubing connectors; and specialized clean energy solutions, featuring extreme high-pressure hydrogen fittings and valves rated up to 105 MPa for hydrogen fueling stations, solid oxide fuel cell (SOFC) piping modules, and solid oxide electrolysis cell (SOEC) fluid delivery systems. The company distributes its products domestically and internationally across key markets in Asia, North America, Europe, and the Middle East. In recent corporate developments, HanSun Engineering completed its initial public offering on the KOSDAQ market (KRX: 452280) in November 2023 to accelerate capital investments in automated production and next-generation product development. The company has expanded its strategic presence in the hydrogen and fuel cell ecosystems by solidifying critical supplier partnerships with Bloom Energy and Bloom SK Fuel Cell for SOFC and SOEC module components, while broadening qualification testing for hydrogen transport trailers and refueling infrastructure. Additionally, HanSun Engineering has expanded its manufacturing and cleanroom capacity in Busan, establishing dedicated high-purity production lines to support the growing demand for semiconductor manufacturing equipment and hydrogen energy installations.
