Iceotope is working with Schneider Electric and Avnet to cool the racks in the world's first climate-positive data centre being built in Sweden.

UK cooling systems pioneer Iceotope has deployed its chassis-level immersion liquid cooling technology at EcoDataCenter’s data centre in Falun, Sweden.

The centre is climate positive, and this is the first use of using its chassis-level immersion liquid cooling to reduce rack cooling energy by up to 90 percent and the overall energy usage by up to 14 percent.

The system was developed by Iceotope, French power giant Schneider Electric and distributor Avnet, combining a GPU server with liquid cooling technology. Avnet’s expertise in integration is key, allowing EcoDataCenter to use the liquid-cooled servers inside Schneider Electric’s NetShelter integrated rack enclosures.

Developed by Iceotope in Sheffield, UK, the cooling enables 46kW per rack, with the core technology capable of scaling to future-proof power densities of over 100kW. Liquid cooling can improve chip and hard drive reliability by providing a lower stable operating temperature, as well as increasing the available white space by eliminating the requirement for hot aisle/ cold aisle layouts. Importantly, the cooling arrangement enables high-grade heat to be captured for reuse in a local renewable energy scheme.

“EcoDataCenter has embraced this innovative new technology as an early-adopter, knowing that companies in the market will soon see the operational and environmental benefits, and follow our lead,” said Lars Schedin, CEO of EcoDataCenter. “The integration of Iceotope, Schneider Electric and Avnet liquid cooling enables us to set ground-breaking, new industry standards for energy efficient, high-availability data centers. Together we are empowering customers to take action for a more sustainable future.”

The chassis-level immersive cooling shows significant capital savings of 14 percent and at least 10 percent energy savings, when compared with traditional air-cooled approaches for a 2MW facility.

“Chassis-level immersion cooling offers colocation, hyperscale and edge computing environments a practical and industry-leading solution for cooling high-density, critical IT loads. We’re delighted to be working alongside EcoDataCenter where our liquid cooling technology is helping to deliver reliable IT services with little or no impact
