Iceotope

Energy · Rotherham, United Kingdom · Founded 2011

Iceotope develops chassis-level precision immersion cooling solutions for the data center industry, targeting high-density computing environments and AI infrastructure. Founded in 2005 by Peter Hopton and David Craig in Sheffield, UK, the company initially focused on creating environmentally friendly computers. The first decade was primarily research-driven until David Craig, who joined as a non-executive director in 2015 and became CEO in 2016, pivoted the company towards a commercially focused entity centered on intellectual property and a licensing model. This strategic shift enabled collaborations with major industry partners like HPE, Schneider Electric, Intel, and Gigabyte. Iceotope’s patented Precision Liquid Cooling (PLC) technology combines attributes of direct-to-chip and tank immersion cooling by using a small amount of non-conductive, dielectric fluid to precisely target and cool the hottest components within a server. This method is executed within sealed, rack-based chassis, making the systems compatible with standard data center infrastructure and impervious to dust and humidity. The technology has demonstrated its capability by cooling chips at loads of 1000W and up to 1500W, a critical milestone for handling the thermal demands of advanced AI and high-performance computing (HPC) workloads. The company's business model revolves around direct sales of its cooling systems, a licensing model for its IP, and co-development of custom solutions with OEMs, ODMs, and hyperscalers. This strategy targets data center managers, engineers, and sustainability officers. Iceotope’s solutions are designed to reduce energy consumption by up to 40%, water usage by up to 100%, and carbon emissions, addressing key sustainability challenges in the data center sector. The company has raised a total of $81.4 million over 10 funding rounds, with significant investments from firms like ABC Impact, nVent, Northern Gritstone, and British Patient Capital, to support its global expansion, particularly in North America, Europe, and Asia.
