LG Uplus Demonstrates Liquid Cooling Technology for Data Centers... Building Eco-Friendly, High-Efficiency AIDC

Next-Generation Cooling Technology Demo Room Opens at Pyeongchon 2 Center
Plans to Introduce at Paju AI Data Center

LG Uplus announced on the 29th that it has opened a next-generation liquid cooling-based demo room at Pyeongchon 2 Center, the largest internet data center (IDC) in the Seoul metropolitan area. Through this demo room, LG Uplus will conduct technology verification to enhance the cooling efficiency and sustainability of its AI data center (AIDC).

This demo room features cooling performance optimized for high-heat-generating artificial intelligence (AI) server environments. Liquid cooling is attracting attention as a key technology for realizing eco-friendly and cost-effective data centers, as it can increase energy efficiency and reduce carbon emissions.

LG Uplus will proactively verify the performance and stability of liquid cooling in an actual high-density AI computing environment. Through this, the company expects to reduce technical risks associated with future GPU performance advancements and infrastructure expansion, and to secure operational efficiency and reliability.

The technology verification taking place in this demo room is being conducted in collaboration with major domestic and international partners, including Vertiv and CoolIT Systems, both specialized in data center liquid cooling, as well as LG Electronics and Global Standard Technology (GST). Commercialization verification and technological advancement efforts will be promoted based on actual operational data.

The cooling technologies being tested 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 servers directly in a tank filled with electrically non-conductive insulating oil to dissipate heat. The core device, the Coolant Distribution Unit (CDU), evenly distributes and collects coolant throughout the servers, thereby increasing the overall system's cooling efficiency and optimizing energy usage.

Previously, in March, LG Uplus unveiled this liquid cooling technology at Mobile World Congress (MWC) 2025 in Barcelona, Spain. The Pyeongchon 2 Center demo room will be operated as a real research and development (R&D) testbed to demonstrate the cooling technology.

Based on the capabilities and know-how gained through this technology verification, LG Uplus plans to fully apply liquid cooling technology at Pyeongchon 2 Center and the upcoming Paju AIDC. Through this, the company expects to achieve cooling energy savings, uninterrupted system operation, reduced operating costs, and improved maintenance efficiency.

Jung Sookyoung, Executive Vice President in charge of AIDC business at LG Uplus, stated, "As the demand for AI and high-performance computing surges, the issue of heat generation in data centers is becoming more severe, making cooling technology a core competency for sustainable AI data center operations. This liquid cooling technology demonstration will serve as an opportunity for LG Uplus to continue its challenges and growth through customer value-driven technological innovation, and as a turning point in leading the construction of eco-friendly and cost-effective AI infrastructure."
