What Nexalus does

Nexalus Ltd. is an Irish private engineering company founded in 2017 and headquartered in Cork, with additional research facilities in Castlepollard (Nexalus Labs) and at Trinity College Dublin's O'Reilly Institute. The company designs and supplies liquid cooling thermal management solutions for electronic systems, built around a patented jet impingement technology in which microjets are directed at chip hotspots rather than channel-based flow, allowing lower pressure operation and higher heat removal density. Its product portfolio comprises SoloFlux GPU cold plates (single-slot cooling for NVIDIA GPUs with TDPs above 450W), ENFLUX CPU cold plates (for processors exceeding 1,000W), the Edge Server (IP66-sealed, fully sealed compute platform operating from -40°C to +55°C without climate control), HYDRONEX thermal interface materials, NXP20 pumps, and 1U rack-based liquid-cooled servers. Solution platforms are organized around four verticals: Data Centers, AI, Edge/5G, and HPC & Gaming, with Thermal Consulting as a parallel service line.

The business operates a partner-mediated, multi-revenue-stream model: (1) hardware sales of proprietary cooling components and complete systems; (2) science-led thermal engineering consulting including first-principles analysis, CFD/CHT simulation, prototype development, and NRE services; and (3) licensing and co-development revenue from multi-year agreements with partners such as Tracewell Systems. Go-to-market is dominated by OEM integration — Alps Alpine is the official global manufacturing and systems integration partner, while Hewlett Packard Enterprise, Dell Technologies (PowerEdge XR11/XR12), Tracewell Systems, TuffTek, UNICOM Engineering, and Overclockers UK (8Pack) embed Nexalus technology into their product lines. Pricing is quote-based and not publicly disclosed, and direct enterprise sales is quote-driven through the company website. End-markets identified include U.S. civilian and military agencies, hyperscale and colocation data center operators, telecom edge deployments, and elite gaming/HPC system builders.

Quality and certification footprint includes ISO 9001, ISO 13485, ISO 14001, IATF 16949, SEAI EXEED, and GDPR compliance. The company is a certified Trinity Campus Company with licensed IP from Trinity College Dublin, holds multiple patents (granted and in process), and acknowledges public funding from Science Foundation Ireland, Enterprise Ireland, and the Disruptive Technologies Innovation Fund. Externally recognized with TIME's 2025 Best Inventions (green-tech category) and Fast Company's 2025 World Changing Ideas Award. Reported headcount is 1-10 employees; no revenue, funding-round history, or investor identities are disclosed in the available sources.
