KKR Exits CoolIT to Ecolab in $4.75 Billion Data Center Cooling Deal

  • KKR has agreed to sell CoolIT Systems to Ecolab for $4.75 billion, representing a roughly 15x return on original equity investment.
  • All CoolIT employees will receive a substantial cash payout from the sale, potentially ranging from one to eight years of annual salary.
  • CoolIT, a leader in liquid data center cooling, has doubled its workforce and expanded its manufacturing footprint since KKR’s 2023 acquisition.
  • CoolIT’s solutions delivered an estimated 2.18 billion kWh in energy savings in 2025, enough to power approximately 200,000 homes for one year.
  • The transaction is expected to close in Q3 2026, subject to regulatory approvals.

The deal highlights the surging demand for energy-efficient data center cooling solutions driven by the proliferation of AI and high-performance computing. KKR’s 15x return underscores the value of targeting niche sectors with strong growth potential, particularly those aligned with sustainability trends. The broad-based employee ownership program, while costly upfront, appears to have significantly contributed to CoolIT’s operational improvements and valuation.

Integration Risk
The success of Ecolab’s acquisition hinges on its ability to effectively integrate CoolIT’s technology and operations, particularly given CoolIT’s rapid growth and employee ownership structure.
Market Adoption
The pace at which hyperscalers and data center operators adopt liquid cooling solutions will dictate CoolIT’s long-term growth trajectory under Ecolab’s ownership.
Employee Retention
How Ecolab manages CoolIT’s employee base, particularly after the payout, will be critical to maintaining the company’s innovative culture and operational expertise.
