LG U+ to Create Eco-friendly and High-efficiency AIDC with Liquid Cooling Technology

LG U+ announced on the 29th that it will open a next-generation liquid cooling-based demo room at the Pyeongchon 2 Center, a large-scale Internet Data Center (IDC), and start technology verification to enhance the cooling efficiency and sustainability of the AI Data Center (AIDC).
This demo room is a next-generation infrastructure optimized for high-heat AI server environments, attracting attention as a core technology for implementing an eco-friendly and economical 'Green-AI Data Center' that can maximize energy efficiency and reduce carbon emissions.
By preemptively verifying cooling performance and stability in an actual high-density AI computing environment, LG U+ expects to minimize technical risks associated with GPU performance evolution and large-scale infrastructure expansion, and provide customers with high levels of operational efficiency and reliability.
The technology verification conducted in this demo room involves global market-leading partners in the data center liquid cooling field, including Vertiv, CoolIT Systems, LG Electronics, and Global Standard Technology (GST), and will be promoted based on actual operational data for commercialization verification and technology advancement.
The cooling technologies verified in the demo room are Direct-To-Chip Cooling and Immersion Cooling. Direct-To-Chip Cooling circulates coolant through a cold plate attached to the server, while Immersion Cooling involves submerging the server in a tank filled with non-conductive insulating oil to remove heat. The 'CDU (Coolant Distribution Unit)', a key device, evenly distributes and recovers coolant throughout the server, enabling cooling efficiency and energy use optimization of the entire system.
LG U+ unveiled this liquid cooling technology at the Mobile World Congress (MWC) 2025 held in Barcelona, Spain, last March, and the Pyeongchon 2 Center demo room will be operated as an actual R&D testbed to verify the cooling technology.
Based on the capabilities and know-how acquired through this technology verification, LG U+ plans to fully apply liquid cooling technology to the Pyeongchon 2 Center, the largest data center in the metropolitan area, and the planned Paju AIDC. Through this, it is expected to create practical results that simultaneously satisfy eco-friendliness and economic efficiency, such as cooling energy savings, system non-stop operation, operating cost reduction, and maintenance efficiency improvement.
Meanwhile, LG U+ plans to operate an AIDC tour program, including the Pyeongchon 2 Center demo room, from the second half of this year to communicate with customers and related industries about AIDC.
Jung Sook-gyeong, Head of AIDC Business at LG U+ (Executive Director), said, "In a situation where the heat problem of data centers is intensifying due to the surge in demand for AI and high-performance computing, cooling technology is a core capability for sustainable AI data center operation," adding, "This liquid cooling technology verification will be an opportunity for LG U+ to continue its challenge and leap forward through customer value-centered technology innovation and a turning point in leading the construction of eco-friendly and economical AI infrastructure."
