What Iceotope does
Iceotope Technologies Limited, founded in 2005 and headquartered in Sheffield, United Kingdom, develops precision liquid cooling technology for data centers, AI infrastructure, and high-performance computing environments. Its core platform is a patented "direct-to-everything" chassis-based architecture that circulates small amounts of environmentally safe, electrically non-conductive dielectric fluid inside fully sealed server or component chassis, capturing heat directly from CPUs, GPUs, memory, storage, power supplies and networking before rejecting it via heat exchangers and dry coolers — eliminating the need for fans, evaporation, or facility water. The company delivers this technology through two main hardware products: the KUL AI compute chassis for high-density datacenter racks and the KUL BOX edge thermal routing cabinet for near-edge AI and HPC inference at hospitals, factories, telecom sites and remote venues.
The portfolio is supported by the Iceotope Labs testing facility in Sheffield (chip-level stress testing up to 1500W, built with Efficiency IT) and the Approved Fluid Vendor Program, a three-stage coolant validation framework that qualifies third-party dielectric fluids from vendors including ENEOS and Engineered Fluids. Iceotope monetizes through quote-based hardware sales bundled with professional services and 3-year parts-and-labor support, and is actively transitioning toward an IP licensing model with ODMs such as Wistron and Sanmina plus cloud service providers, with target customers spanning hyperscalers, colocation operators (maincubes), regulated on-premises enterprises in healthcare, finance and government, telecommunications, manufacturing, media, and rugged-edge sites.
The company has cumulatively raised approximately $53 million in venture funding, including a $26 million Series B round closed in May 2026 co-led by Two Seas Capital and Barclays Climate Ventures, and holds more than 200 granted and pending patents. Its management team includes co-CEO Nathan Blom, Chief Innovation Officer Neil Edmunds (named on 23 patents), Vice President of Marketing Emily Hutson, Head of Manufacturing & Quality Assurance Angus Hugues (PhD), and sales/technology leader Ian Ferguson; the firm operates from the UK with a planned/opened US office and active Korean-market positioning.

Iceotope product offering
Product offeringCore offering
Iceotope develops and sells a patented "direct-to-everything" precision liquid cooling platform that circulates electrically non-conductive dielectric fluid inside fully sealed server or chassis to cool CPUs, GPUs, memory, storage, PSUs, and networking components. The company delivers this technology through two flagship hardware products — KUL AI (precision liquid-cooled server chassis for high-density AI/HPC data centers) and KUL BOX (24U sealed edge thermal routing cabinet for near-edge deployments) — supported by the Approved Fluid Vendor Program, Iceotope Labs validation services, and an emerging IP licensing model for OEMs and ODMs.
Product overview
Iceotope offers a unified precision liquid cooling platform delivered through two core hardware products — the KUL BOX edge thermal routing cabinet (for near-edge AI/HPC deployments) and the KUL AI compute chassis (for high-density datacenter racks) — both built on the company's patented "direct-to-everything" dielectric-fluid cooling technology that captures nearly all heat at the source while cutting power, water, and carbon. The platform is reinforced by the Approved Fluid Vendor Program (validating third-party dielectric coolants such as ENEOS IX Series and Engineered Fluids ElectroCool EC-110), the Iceotope Labs testing facility in Sheffield, and an integrated delivery/support model (hardware integration, 3-year service guarantee, and turnkey deployment via partners like UNICOM Engineering). Together these products let customers run AI and HPC workloads across CSP/hyperscale, enterprise, telecom, manufacturing, healthcare, media, travel, and edge environments with closed-loop, near-waterless cooling.

Iceotope competitors and assessment
Company assessmentDirect peers
- Asetek: Asetek is a direct competitor in liquid cooling for data centers, HPC and AI workloads, selling closed-loop and direct-to-chip cooling systems to OEMs and channel partners. Highly comparable product category, customer base (gaming OEMs extending into data center) and precision cooling focus, though Asetek's heritage is in consumer/gaming cooling rather than dielectric chassis immersion.
- CoolIT Systems: CoolIT Systems is a leading direct liquid cooling (CDU and cold plate) provider for HPC, AI and enterprise data centers. Competes head-to-head with Iceotope in the same hyperscaler and enterprise sales motion, though CoolIT's technology is direct-to-chip cold plates rather than Iceotope's dielectric chassis approach.
- Green Revolution Cooling (GRC): GRC is a specialist in single-phase immersion cooling for data centers, targeting HPC and AI workloads with dielectric coolant tank systems. Directly comparable customer segments and immersion-adjacent architecture, though GRC uses full-tank immersion rather than Iceotope's sealed chassis approach.
