Its precision liquid cooling delivers coolant across all server components, direct-to-everything, covering CPUs, GPUs, memory, networking and power rather than only the hot chips, in a sealed chassis-level design. Claimed results are energy use down up to 40 percent and water use down up to 96 percent, near-silent from eliminating server fans, sealed for harsh environments. Products are KUL AI for rack-scale and KUL BOX for edge servers. It has surpassed 200 granted and pending patents. On 2026-05-14 it raised a USD 26 million Series B led by Two Seas Capital and Barclays Climate Ventures, with Edinv, ABC Impact, Northern Gritstone and the British Business Bank participating. The reason it stays KEEP-WATCH despite a current round is scale: USD 26 million in year twenty-one, against ZutaCore at roughly USD 200 million and Corintis at USD 58 million in under a year, and no disclosed customer, deployment count or revenue. Its framing that both air and direct-to-chip cannot sustain 1 MW racks is the bet, and nothing found shows an operator agreeing at scale. Revisit trigger: a named production deployment or a disclosed revenue figure.","sub_category":"Cooling & thermal","signals_total":5,"url":"https://www.frontiertechintelligence.com/companies/iceotope","title":"Iceotope · ai core, Sheffield, England, United Kingdom · scores, facts and signals · Frontier Tech Intelligence","description":"Iceotope develops and supplies liquid-cooling systems for data-center servers, including chassis-based precision liquid cooling and liquid immersion cooling.
