How KyotoCooling® works
KyotoCooling® is a patented indirect air-to-air cooling system that transfers heat from data centers to the outside air using a rotary heat exchanger. Internal and external airflows remain completely separate, preserving air quality while maximizing energy efficiency.
The system operates in a closed loop and self-adjusts to match real-time IT loads and local climate conditions. No water is used, there’s no evaporation, no contamination, and no complex plumbing. It’s a clean, scalable, and cost-effective solution for mission-critical cooling.
