Top 10 Companies in the Single‑Phase Immersion Cooling Mineral Oil Data Center Market (2026): Market Leaders Powering Global Data Centers

MARKET INSIGHTS

Global single‑phase immersion cooling mineral oil data center market size was valued at USD 1.82 billion in 2025. The market is projected to grow from USD 2.09 billion in 2026 to USD 7.64 billion by 2034, exhibiting a CAGR of 15.5% during the forecast period.

Single‑phase immersion cooling using mineral oil is an advanced thermal management technology in which IT hardware components – including servers, processors, and memory modules – are fully submerged in a thermally conductive, electrically non‑conductive mineral oil dielectric fluid. Unlike traditional air‑cooling systems, the mineral oil absorbs heat directly from the hardware and circulates it to a heat exchanger, all while the fluid itself remains in a single liquid phase throughout the process. This approach delivers significantly higher heat dissipation efficiency compared to conventional cooling methods, making it particularly well‑suited for high‑density computing environments such as hyperscale data centers, high‑performance computing (HPC) facilities, and AI inference infrastructure.

The market is gaining strong momentum driven by the exponential growth in data center power densities, accelerating AI and machine learning workloads, and mounting pressure on operators to reduce power usage effectiveness (PUE) ratios. Furthermore, increasing global sustainability mandates and corporate net‑zero commitments are pushing data center operators toward energy‑efficient alternatives to traditional air‑cooling systems. Industry deployments have been expanding steadily, with major technology firms and colocation providers actively piloting and scaling immersion cooling installations. Key players operating in this market include Submer Technologies, GRC (Green Revolution Cooling), Engineered Fluids, Midas Green Technologies, and Fujitsu, among others, each offering differentiated mineral oil‑based immersion cooling solutions tailored to modern data center requirements.
