Company profile
DOOJIN Corporation has developed Korea’s early cryogenic industrial-gas market and has contributed to the semiconductor, food-distribution, aerospace, biotechnology, medical, automotive, and research-laboratory fields. Its renewable-energy activities involving LNG and hydrogen include technical support and Total Solution work for Korea’s first hydrogen filling station connected with Hyundai Motor Namyang R&D Santa Fe hydrogen-vehicle development, completion of an LCNG filling station, vehicle LNG systems, and installation of vacuum-insulated piping for liquefied hydrogen. DOOJIN Corporation has designed, built, and installed complex cryogenic-system solutions for a variety of applications over the past 29 years. The company positions its business around Engineering & Cryogenic Total Solution activities spanning industrial and cryogenic gas plants from design through manufacturing and construction. Its company information also presents DOOJIN Corporation as the Korean developer of cryogenic storage-vessel and vacuum-insulated-piping technology, with capabilities covering storage tanks, storage vessels, freezers, and double-insulated vacuum piping. Customer support is part of the operating scope, together with product inquiries, catalogs and educational materials, delivery and construction references, and information for customers and partners.
Exhibits
DOOJIN Corporation supplies special piping that transfers liquid gases such as LN2, LO2, and LAR from storage tanks to the equipment where the gases are used. Its cryogenic vacuum-insulated piping uses insulation between the inner and outer pipes and a vacuum-insulated structure to minimize losses caused by vaporization during liquid-gas transfer. The vacuum-piping range includes vacuum-insulated piping (VJP), piping types and components, vacuum-jacket valves, vacuum flexible hoses, and a Phase Seperator for gas-liquid separation, together with high-pressure-gas construction work. Cryogenic equipment includes LGC cryogenic vessels, cryogenic vessels, liquefied-helium tanks, cryogenic storage tanks, Chart VS Series and Perma-Cyl Series products, cryogenic design and manufacturing, and cooling equipment for cryogenic vessels. Application equipment includes cryogenic application devices, LN2 rapid food freezing, and an LN2 injection device identified as DOSER. The DOOJIN/MVE cryogenic-storage range includes DOOJIN liquid-nitrogen containers, DOOJIN liquid-nitrogen freezers, MVE LAB and Shipper vessels, MVE XC and SC vessels, MVE Cryosystem products, and accessories for liquid-nitrogen containers. Cryogenic parts and support items include cryogenic components, cryogenic safety products, cryogenic temperature sensors and level alarms, and a cryogenic flowmeter identified as Flowcom. The broader offering also covers cryogenic testing, cryogenic test equipment, a GAS MIXER, water-electrolysis equipment, engineering, hydrogen generators, cryogenic parts, and CO2 precision cleaning. For liquid hydrogen, the company’s project record specifically includes installation of vacuum-insulated piping, while its broader experience covers the design, construction, and installation of complex cryogenic systems.
