Alfa Laval has introduced FreeWaterLoop, an external liquid-based cooling system for the data center facility loop. The company says the system is engineered to improve efficiency and energy savings for high-density computing, and to support a shift from traditional facility-loop air-based cooling to liquid-based cooling.
Alfa Laval says FreeWaterLoop integrates advanced pump engineering, high-performance heat exchanger technology, and filtration into a single system. The company positions it as a scalable, fully integrated approach that uses natural water sources for heat transfer, aiming to provide a continuous, reliable cooling flow.
According to Alfa Laval, the system harnesses stable temperatures and the heat transfer capacity of natural water sources to minimize net water consumption and return water to its origin. The company also says FreeWaterLoop reduces the physical plant footprint of facility cooling because it occupies less space than air-based systems.
“We’re seeing unprecedented shifts in the data center landscape as AI drives higher heat loads and customers push for more sustainable infrastructure,” said Thomas Møller, President of the Energy Division, Alfa Laval. “Alfa Laval is responding to these challenges by combining our strengths across the business to deliver the next generation of efficient, reliable thermal and pumping solutions,”
Alfa Laval reports it introduced FreeWaterLoop on 4 March 2026 at Data Center World in London.
