Mubadala Investment Company has signed a definitive agreement to sell its minority stake in CoolIT Systems to Ecolab as part of a $4.75 billion transaction led by KKR.
Mubadala had invested in CoolIT in 2023 alongside KKR through its Global Impact Fund II, backing the company’s role in advancing liquid cooling technologies for data centres. With AI-driven compute demand rising, CoolIT has positioned itself as a key enabler of sustainable and high-density digital infrastructure.
Liquid cooling is increasingly critical as traditional air-cooled data centres can consume up to 50% of facility energy for cooling. In contrast, CoolIT’s solutions reduce cooling energy usage by 30–40% while lowering water consumption through closed-loop systems. The company’s technologies are now deployed across more than 300 data centres globally, supporting hyperscalers in improving efficiency.
Mubadala highlighted that its investment thesis has played out as expected, with liquid cooling emerging as a core component of next-generation infrastructure. The partnership with KKR and CoolIT’s management drove strong operational growth, including a manufacturing expansion beyond 300,000 sq ft, a 25x increase in CDU capacity, and a doubling of its workforce.
CoolIT is now positioned for significant financial growth, targeting approximately 4x revenue and 10x EBITDA expansion through 2026.
Ecolab’s acquisition is expected to further strengthen CoolIT’s capabilities, particularly in water management, aligning with the increasing sustainability demands of global data centre operators.
The transaction comes amid rapidly growing pressure on data centre resources. By 2030, global data centre energy consumption is projected to reach 945 TWh, more than double 2024 levels, while water usage is expected to rise to 450 million gallons per day. CoolIT’s solutions alone delivered an estimated 2.18 billion kWh in energy savings in 2025, equivalent to powering around 200,000 homes annually.
