LG Electronics Launches Oil-Free Turbo Chiller for AI Data Center Cooling

LG Electronics has introduced a new air-cooled, oil-free inverter turbo chiller aimed at the artificial intelligence data center market, as the South Korean electronics giant moves to deepen its footprint in the fast-expanding data center cooling sector. The launch marks a significant expansion of the company's AI data center cooling portfolio, which previously consisted primarily of screw chillers, and signals its ambition to capture a larger share of a market driven by the relentless growth of compute-intensive AI workloads.

The new system is built around LG's independently developed oil-free magnetic bearing technology, which uses electromagnetic force to suspend the rotating shaft, thereby reducing mechanical friction and improving overall performance. By eliminating lubricating oil from the system, LG has also removed the need for oil circulation pumps and associated piping. The design additionally prevents oil films from forming inside heat exchangers, a common issue that can degrade cooling efficiency over time. Together, these engineering choices are intended to lower maintenance requirements and extend the operational lifespan of the equipment.

A central feature of the chiller is its refrigerant-based free-cooling technology, which activates when outdoor temperatures are relatively low. Under such conditions, the system can shut down the compressor entirely and rely on outside air to cool condensed refrigerant, allowing it to circulate naturally through the cooling loop. LG said compressors account for more than 80% of a chiller's electricity consumption during operation, making compressor downtime a critical lever for reducing energy use. According to the company, its refrigerant-based free-cooling system can cut annual electricity consumption by approximately 30% compared with conventional water-based free-cooling systems, directly improving a data center's power usage effectiveness — a key metric for operators under pressure to reduce energy costs and meet sustainability targets.

The higher-capacity system is designed not only to reduce electricity consumption but also to lower total cost of ownership, helping data center operators comply with increasingly stringent global environmental and carbon regulations. "This new product brings together everything AI data center customers need, from outstanding efficiency to the ability to rapidly deploy modular systems on-site," said Lee Jae-sung, head of LG Electronics' Eco Solution business. "We will use our differentiated technology to solidify our leadership in the rapidly changing global AI data center cooling market," Lee added.

The launch underscores the intensifying competition among industrial equipment makers to supply cooling infrastructure for AI data centers, where soaring rack densities and power demands are pushing traditional cooling architectures to their limits. As hyperscalers and colocation providers race to build out capacity, suppliers that can deliver energy-efficient, modular and quickly deployable cooling solutions are likely to gain a decisive advantage. LG's move reflects a broader industry trend in which electronics and HVAC manufacturers are converging on the data center cooling market as one of the most promising growth avenues in the coming decade.
