LG Electronics has released an air-cooled, oil-free inverter turbo chiller designed specifically for the high heat outputs of AI data centers. The modular system utilizes magnetic levitation to support rotating shafts, eliminating the need for lubricating oil or circulation pumps.
Why it matters
AI servers generate significantly more heat than traditional server architectures, placing a heightened cooling burden on global data infrastructure. This chiller addresses that thermal load by optimizing efficiency and modularizing deployment via ISO standard containers.
The system achieves a 20% improvement in partial load efficiency versus standard inverter screw chillers and reduces annual power consumption by 30% against traditional water-based models. It functions without lubricating oil by using magnetic levitation to suspend the rotating shaft.
The players
LG Electronics
A global consumer electronics and appliance manufacturer that builds HVAC systems and industrial power solutions for large-scale data infrastructure.
The details
The chiller employs magnetic levitation, a process that uses electromagnetic force to suspend a rotating shaft in mid-air, which eliminates friction and the requirement for traditional lubricating oil. It also features refrigerant free cooling, a method that circulates coolant without engaging the compressor during low outdoor temperatures to lower energy draw. Components including pumps, valves, and emergency buffer tanks are integrated into ISO standard containers to facilitate modular capacity expansion for growing server loads.

The Tech Race
This development represents a significant step in the transition away from traditional mechanical cooling hardware like inverter screw chillers. It shifts the competitive landscape by favoring magnetic-bearing systems that minimize maintenance and energy waste in high-density compute environments.
Data center operators can adopt this containerized solution to modularly scale cooling capacity without the complexity of water-based plumbing. The system is designed to lower operating costs by reducing total power draw during cooler outdoor periods through refrigerant-free circulation.
The takeaway
This technology highlights a shift toward high-efficiency, oil-free cooling as a standard for AI-intensive data centers. Watch for real-world benchmark data in upcoming infrastructure deployments to confirm if the 30% energy savings holds in diverse climate zones.
