ZutaCore and Munters join forces to deliver a waterless data centre architecture for AI factories

The solution brings an unprecedented reduction in OPEX , power consumption and energy usage to the data centre .

ZutaCore , a leading provider of direct-to-chip , waterless liquid cooling solutions , and Munters , a global leader in energy-efficient air treatment and climate solutions , have announced the integration of their two platforms to provide a two-phase , waterless liquid cooling solution to sustainably cool AI factories faced with massive power densities driven by AI accelerators .

The solution is designed to liquid cool 100 + MW of AI workloads . The combined system works seamlessly inside an AI factory , with Munter ’ s SyCool ( N + 1 ) rejecting the heat outside the data centre ( facility loop ) and ZutaCore Hypercool , removing the heat away from the AI accelerators ( technical loop ) in highly efficient closedloop systems that are easy to operate and offer the most optimised PUE and WUE factors for a sustainable , costefficient , high-performing AI data centre .
“ With AI factories being 5-10x more dense than traditional data centres , there is no other way to cool AI silicon and remove this amount of heat without liquid cooling ,” said Erez Freibach , Co-founder and CEO , ZutaCore . “ Furthermore , GPUs are pushing thermal boundaries with known hot spots . AI workloads demand GPU density and stable thermal environments to maximise AI performance .
“ This is also where two-phase , direct-to-chip liquid cooling separates itself from any other solution in the market because it uses no water , takes up little real estate , requires much less power and allows a heat recovery pathway . These are the key reasons HyperCool is already being selected in key AI factories around the globe . With this partnership with Munters , we are well positioned to grow this leadership even further ,” added Freibach .
Stefan Aspman , President of Business Area Data Center Technologies , Munters , said : “ Combining the advanced closedloop systems of Munters and ZutaCore delivers an unmatched end-to-end solution , which is uniquely positioned to meet the demands of high-density , high-value environments .
“ ZutaCore and Munters are pioneering a blueprint for sustainable AI data centre architecture ,” Aspman added . “ It not only addresses intense heat loads with distinct advantages through its waterless two-phase solution , but also sets a new benchmark for CAPEX and OPEX savings , challenging other cooling technologies available today .”
Combing two closed-loop systems
As part of the partnership , Munters has integrated the HyperCool closed-loop system at the server and rack level with the Munters closed-loop system that provides the ability to remove heat from the data centre without a facility water loop .
Leveraging a two-phase , liquid cooling process , this system features tanks of heat transfer fluid on the roof that are brought down on demand to cool the GPUs and CPUs . The heat is removed outside the facility or can be reused for other applications , such as heating adjacent facilities or harvesting energy for reuse and further reducing PUEs .
ZutaCore ’ s HyperCool has been proven to cool the hottest processors of 2,800W at a PUE as low as 1.05-1.07 increasing compute density . This delivers 10-20 % better energy efficiency with dynamic cooling , smaller pumps and no performance degradation over time .
The heat transfer fluid never has to be replaced and poses none of the risks that water presents in terms of leakage or corrosion .
The system allows for higher server densification needed in AI factories , consuming up to 50 % less space than air-assisted liquid-cooled data centres and up to 75 % less space than immersion cooling . �
