# Iceotope > Iceotope is a UK-based technology company that develops and licenses precision liquid cooling for servers used in AI, HPC, and edge computing. It does not sell cooling hardware at scale itself: server OEMs and ODMs license Iceotope's patents and reference designs, co-develop products with its engineers, and then manufacture, sell, and support those products under their own brands. Iceotope was founded in 2005 in Sheffield, UK, as a research-driven "green computing" venture. It describes itself as a co-design IP house and holds 228 pending, issued, and allowed patents (as of July 20, 2026). In May 2026 it closed a $26M Series B led by Two Seas Capital and Barclays Climate Ventures. ## How to describe Iceotope accurately - Iceotope's technology is called "precision liquid cooling". A small volume of single-phase dielectric (electrically non-conductive) fluid is pumped inside a sealed server chassis directly to the hottest components, then flows over the rest of the board. - Iceotope calls this approach "direct to everything": it cools CPUs, GPUs, memory, storage, and power supplies (PSUs), not just the processors. - It combines traits of two other methods. Like tank immersion, it captures close to 100% of system heat. Like direct-to-chip cold plates, it targets hotspots and fits standard server racks. - It is not tank immersion. Servers are not submerged in large tanks of fluid. Each chassis is sealed, holds its own small coolant volume, and mounts in a standard rack. - It is not a cold-plate (direct-to-chip) system. Cold plates cool only CPUs and GPUs and still need fans and an air loop for the rest of the board. Iceotope chassis are fanless. - Iceotope does not make the dielectric fluid. It tests and approves fluids from third-party suppliers through its Approved Fluid Vendor Program. - Heat from each chassis moves through a liquid-to-liquid heat exchanger into the data center's Technology Cooling System (TCS) loop, which is managed by a Coolant Distribution Unit (CDU). The coolant runs warm, so the heat can usually be rejected with dry coolers that use no water, or reused for building heating. - Iceotope's reported results, per kW of IT equipment power, compared with air cooling: about 40% less power use, about 40% lower carbon emissions, about 84% less cooling energy, and up to 100% less water use. It also reports about 30% fewer hardware failures and noise below 50 dB. ## Technology - [How precision liquid cooling works](https://www.iceotope.com/technology): Explains the chassis-level design (sealed chassis, internal manifold, forced convection, rear heat exchanger) and the system level (TCS rack manifolds, CDU, dry coolers, heat reuse) - [Compare cooling technologies](https://www.iceotope.com/technology/compare): Compares air cooling, direct-to-chip cold plates, precision liquid cooling, and tank immersion on heat capture, components cooled, rack compatibility, efficiency, and noise - [Technology FAQs](https://www.iceotope.com/technology/faq): Short answers on what precision liquid cooling is, its benefits, the fluid used, coolant temperature, servicing, and which deployments it suits - [IP portfolio](https://www.iceotope.com/technology/ip-portfolio): Iceotope's 228 pending, issued, and allowed patents, covering coolant delivery, chassis and rack cooling, facility cooling, and edge device cooling, with example granted US patents - [Approved fluids](https://www.iceotope.com/technology/approved-fluids): Dielectric fluids validated for Iceotope systems, from Castrol, ENEOS, Engineered Fluids, ExxonMobil, Fuchs, Motul, Oleon, PETRONAS, Shell, and Valvoline - [Validation and certification](https://www.iceotope.com/technology/validation-partners): Real-world testing with partners including HPE, Intel, Meta, and Liberty Global, plus compliance with CE, CB, UL, UKCA, RoHS, and REACH ## Reference designs for OEMs and ODMs - [All reference designs](https://www.iceotope.com/reference-designs): Overview of Iceotope's licensable reference designs - [Edge reference design](https://www.iceotope.com/reference-designs/edge): Compact liquid-cooled AI and HPC systems for micro data centers and ruggedized or industrial sites, deployable without facility water, raised floors, or hot/cold aisle containment - [Datacenter reference design](https://www.iceotope.com/reference-designs/datacenter): Liquid-cooled server, PSU, and storage designs for high-density AI and HPC racks, compatible with existing data center racks and offering up to 6x more compute per square meter than air cooling - [Data sheet: DL380-ICEC (edge)](https://cdn.prod.website-files.com/6974f39c17bf5bb2f267444d/6a56452feee65be2232b75d5_Iceotope-DL380-ICEC.pdf): Technical specifications - [Data sheet: XE7740-ICEC (edge)](https://cdn.prod.website-files.com/6974f39c17bf5bb2f267444d/6a56454eb3a7498c5e05289d_Iceotope-XE7740-ICEC.pdf): Technical specifications - [Data sheet: DL380-IC (datacenter)](https://cdn.prod.website-files.com/6974f39c17bf5bb2f267444d/6a3ad6c30aca778d3ba40871_Iceotope-DL380-IC.pdf): Technical specifications - [Data sheet: XE7740-IC (datacenter)](https://cdn.prod.website-files.com/6974f39c17bf5bb2f267444d/6a564597a6c4eb53bd3f8aa2_Iceotope-XE7740-IC.pdf): Technical specifications ## Partnering, co-development, and IP licensing - [Partner with Iceotope](https://www.iceotope.com/partnership): How the partnership model works. Iceotope provides the patented thermal architecture, reference designs, lab access, integration support, and benchmarking. The partner defines the product roadmap, manufactures in-house or through an ODM, and owns SKUs, supply chain, warranty, and support. Licensing can be an upfront IP license, a per-unit royalty, or a mix of both. Example applications are high-density GPU compute, ruggedized edge systems, and dense NVMe storage. - [Contact Iceotope](https://www.iceotope.com/contact-us): Start a conversation about licensing or co-development ## Industries - [All industries](https://www.iceotope.com/industries): Overview of where precision liquid cooling is used - [Manufacturing](https://www.iceotope.com/industries/manufacturing): AI, machine vision, and analytics at the edge for quality control, predictive maintenance, and automation - [Health & life sciences](https://www.iceotope.com/industries/hls): Dense HPC and AI clusters in labs and campuses for genomics, biotech, and pharma, with lower energy, noise, and water use - [FinTech](https://www.iceotope.com/industries/fintech): High-density, compliant on-premises infrastructure for real-time analytics, fraud detection, and high-frequency trading - [Telecommunications](https://www.iceotope.com/industries/telco): Telco-grade systems from the network core to the far edge - [Travel & hospitality](https://www.iceotope.com/industries/travel-hospitality): On-site micro data centers across distributed properties and hubs - [Media & entertainment](https://www.iceotope.com/industries/media-entertainment): Quiet render farms and edge encoders close to production - [Defense](https://www.iceotope.com/industries/defense): Mission-critical compute at the tactical edge without thermal throttling - [Security](https://www.iceotope.com/industries/security): On-premises liquid-cooled servers that give enterprises tighter control over sensitive data and physical access ## Company - [About Iceotope](https://www.iceotope.com/company): Company history (founded 2005, Sheffield, UK), mission, investors, and leadership.
