Nitrogen 35,000 N㎥/h, Oxygen 12,000 N㎥/h
Investing 68 billion won over 2 years to meet demand in Yeocheon Industrial Complex

Daesung Industrial Gases Co., Ltd. (CEO Oh Gyu-seok), an industrial gas and engineering specialist, is responding to the demand for industrial gases in the Yeocheon Industrial Complex, including LG Chem, by operating the Yeocheon Plant 6 in which it invested KRW 68 billion over the past two years.
Daesung Industrial Gases recently announced that it plans to begin full-scale operation of its Yeocheon Plant 6, currently under construction in the Yeosu National Industrial Complex in South Jeolla Province, in early June.
Daesung Industrial Gases Yeocheon Plant No. 6, located within the GS Caltex Yeosu Plant, was built over the past two years with an investment of approximately KRW 68 billion, with a production capacity of 35,000 N㎥/h of nitrogen and 12,000 N㎥/h of oxygen. It is reported that it is currently in the final test run, with full-scale gas supply scheduled for early June.
With the completion of Yeocheon Plant No. 6, Daesung Industrial Gases will be able to provide a stable supply of gas while responding appropriately to the increasing gas demand of existing companies in the Yeocheon Industrial Complex, including LG Chemical.
Daesung Industrial Gases, which welcomed MAIF (Macquarie Asia Infrastructure Fund), managed by Macquarie Asset Management Group, the world's largest infrastructure asset management company, as a new shareholder in February of last year, announced at its vision declaration ceremony that year a target of KRW 1.1 trillion in sales and KRW 350 billion in EBITDA (earnings before interest, tax, depreciation, and amortization) by 2025.
Since its establishment in 1979, the company has continuously improved its industrial gas technology by establishing an ultra-low temperature research center and training technical personnel, and has also developed technologies for semiconductors, displays, secondary battery materials, oil refining, and petrochemicals. Daesung Industrial Gases, which has grown together with leading customers, is recognized in the industry as the only native company that competes on equal terms with foreign industrial gas companies.
Since entering Korea in 2000, Macquarie Group has continued to invest in various sectors such as infrastructure, energy, and renewable energy based on a positive outlook for the Korean market, and in 2020, acquired 100% of Daesung Industrial Gases from MBK.
Macquarie is known to be positive about the growth potential of Daesung Industrial Gases and the industrial outlook of its major customers, major domestic corporations, and is actively supporting the expansion of Daesung Industrial Gases' new businesses and promoting business expansion.
Meanwhile, Oh Gyu-seok, who was newly appointed as CEO of Daesung Industrial Gases in April of this year, worked at Monitor Group and Bain & Company, a global strategy consulting firm, before serving as CEO of C&M and president of Daerim Industrial. He recently served as head of the New Growth Division at POSCO, leading efforts to discover new growth engines such as POSCO's secondary battery materials business.
As a new business development expert, President Oh is expected to accelerate the growth of Daesung Industrial Gases’ new business sector by seeking synergies with eco-friendly and renewable infrastructure businesses in which Macquarie is actively investing, such as the eco-friendly gas business, as well as the growth of the existing industrial gas business, and to respond quickly to major changes in the management environment, such as ESG.
It is anticipated that Daesung Industrial Gases, which has been re-armed with new shareholders and management, will change into something different from the past.
