LG Electronics said on the 28th that it will join hands with SK Enmove and U.S.-based immersion cooling specialist GRC (Green Revolution Cooling) to expand its AI data center cooling solution portfolio to include immersion cooling.
The three corporations signed a memorandum of understanding (MOU) the previous day at the LG Electronics chiller business site in Pyeongtaek, Gyeonggi Province, to expand their AI data center cooling solution business. Through this collaboration, they will integrate cooling solutions such as LG Electronics' chillers, cooling distribution units (CDU), and fan wall units (FWU), which evenly distribute heat loads for precise cooling control; SK Enmove's immersion cooling fluid; and GRC's immersion cooling tanks to conduct a proof of concept (PoC) for an immersion cooling solution. The PoC will take place at a dedicated AI data center testbed established within the Pyeongtaek chiller site. Through this, the three companies plan to actively identify new business opportunities based on immersion cooling solutions.
Immersion cooling is a technology that cools heat-generating electronic devices such as data center servers by submerging them directly in a special non-conductive cooling fluid. It uses a liquid with higher thermal conductivity than air to remove heat quickly. The power usage effectiveness (PUE), which indicates a data center's energy efficiency, is the lowest among existing data center cooling methods, delivering strong power-saving effects.
By adding immersion cooling technology to its cooling solution portfolio, LG Electronics plans to further strengthen its position as an optimal cooling solution provider for AI data centers. Earlier this month at Data Centre World Asia 2025 in Singapore, it unveiled a new cooling distribution unit that more than doubled cooling capacity from the existing 650 kW (kilowatts) to 1.4 MW (megawatts), and it continues to add to its cooling solution lineup.
Recently, the company has also signed an agreement to supply cooling solutions to the Middle East's largest "net-zero AI data center," which is being built in Neom City, Saudi Arabia; secured a contract worth hundreds of billions of won to supply air-cooled free-cooling chillers to a U.S. hyperscale AI data center; and secured supplies of oil-free inverter turbo chillers and air handling units (AHU) to an AI data center in Jakarta, Indonesia.
SK Enmove, a leading corporation in premium lubricants, is strengthening global partnerships to build the immersion cooling ecosystem by providing next-generation thermal management solutions such as immersion cooling fluids. It began developing immersion cooling fluid in Korea in 2022 for the first time domestically and jointly developed a data center immersion cooling system with GRC through an equity investment in GRC.
GRC is a global leading immersion cooling solutions corporation headquartered in Texas. Since introducing the industry's first immersion cooling solution in 2009, it has worked with global IT corporations to commercialize immersion cooling technology.
Nam Jae-in, head of green growth at SK Enmove, said, "We expect that by effectively combining the strengths of the three companies, which have immersion cooling technology and cooling market experience, we can further enhance competitiveness in the global data center immersion cooling market," and added, "We will lead growth and change in the cooling market with innovative solutions and strategic partnerships."
Peter Poulin, GRC chief executive officer (CEO), said, "This collaborative partnership promoted by LG and SK will deliver innovative and quantitatively proven value to AI data center customers," and noted, "We plan to help customers quickly adopt highly complete cooling solutions and build a stable operating environment."
Lee Jae-sung, head of the ES Business Division (vice president) at LG Electronics, said, "We pursued this collaboration to maximize energy efficiency and cooling performance, the core tasks of AI data centers," and added, "We will strengthen competitiveness in the global market by providing differentiated cooling solutions in the rapidly growing AI data center industry."
