Telehouse launches new liquid cooling lab

Author: Simon Rowley

Addressing the thermal challenges of today’s high-performance computing and AI workloads, Telehouse International Corporation of Europe, a global data centre service provider, has announced the launch of its liquid cooling lab following the development of strategic partnerships with four of the world’s most advanced liquid cooling technology providers.

From early 2025 onwards, the four companies – Accelsius, EkkoSense, JetCool, and Legrand – will showcase their advanced cooling technologies at the new, state-of-the-art liquid cooling lab at Telehouse South, the latest addition to Telehouse’s London Docklands campus. This project will enable Telehouse customers to explore cutting-edge liquid cooling innovations and find an option that works best for their needs.

Accelsius is bringing its NeuCool platform to Telehouse’s London data centre, introducing a two-phase, direct-to-chip cooling technology that uses a waterless, non-conductive refrigerant for heat removal. Removing an average heat flux of 250W/cm² and hot spot heat fluxes above 500W/cm², NeuCool offers substantial performance headroom for AI and high-performance computing.

The deployment will include the Accelsius Thermal Simulation Rack, a patent-pending system with Load Simulation Sleds that replicate high-power servers, enabling users to control, monitor, and measure the impressive cooling and computational performance delivered by NeuCool technology. Telehouse clients will also have access to a live performance portal for real-time data and seamless demonstrations of the system’s capabilities.

JetCool, a Flex company, will provide its SmartPlate System in the Liquid Cooling Lab – a self-contained liquid cooling product in compact 1U and 2U form factors. Requiring no piping, plumbing, or facility modifications, the SmartPlate System provides a hassle-free approach to efficient cooling. JetCool’s patented microconvective liquid cooling technology handles the highest-power CPUs, GPUs, and AI accelerators, cooling Superchips over 3,500W and outperforming microchannel-based designs by up to 30%, as validated by third-party testing.

JetCool’s product suite extends beyond self-contained systems to integrated rack-level liquid cooling products. These incorporate JetCool’s in-rack SmartSense Coolant Distribution Unit (CDU), capable of cooling up to 300kW per rack or neighbouring racks, with scalability to row-based configurations exceeding 2MW. JetCool’s flexible technology enables Telehouse tenants to choose products ranging from liquid-assisted air cooling to full-scale liquid cooling, meeting the demands of today’s high-performance computing and AI workloads.

Legrand will install its USystems ColdLogikCL20 Rear Door Heat Exchanger (RDHx), supporting over 90kW capacity per cabinet. Its ColdLogik RDHx negates heat at source and removes the need for air-mixing or containment. Ambient air is drawn into the rack via the IT equipment fans, and the hot exhaust air is expelled from the equipment and pulled over the heat exchanger assisted by EC fans mounted in the RDHx chassis. The exhaust air transfers heat into the coolant within the heat exchanger, and the newly chilled air is expelled into the room at, or just below, the predetermined room ambient temperature designed around sensible cooling.

Both processes are managed by the ColdLogik adaptive intelligence, using air-assisted liquid-cooling to control the whole room temperature automatically at its most efficient point.

EkkoSense, a provider of AI-powered data centre optimisation software, will deploy to Telehouse’s lab its innovative EkkoSim ‘what-if?’ scenario simulations; low-cost air-side and liquid-side monitoring sensors; web-based EkkoSoft Critical 3D visualisations with analytics and AI-powered advisory; and anomaly detection tools. Because the latest AI compute hardware and hybrid cooling infrastructure introduce new levels of engineering complexity, EkkoSense deploys the power of AI to capture, visualise, and analyse data centre performance.

Telehouse has already deployed EkkoSense’s EkkoSoft Critical platform across its London Docklands campus, optimising data centre cooling performance. A key benefit for the Telehouse operations team has been how the EkkoSense AI-powered platform has not only improved visibility into cooling and capacity performance, but also helped to reduce the administrative burden for already busy Telehouse team members.
