With this acquisition, Trane Technologies aims to scale these innovations globally and deliver end-to-end cooling solutions.
The acquisition builds on Trane Technologies’ minority investment in LiquidStack in 2023. The full integration of LiquidStack will enable Trane Technologies to expand its portfolio of thermal management solutions, including chillers, heat rejection systems, controls, liquid distribution, and on-chip cooling. This collaboration will deliver comprehensive cooling strategies designed to address the evolving requirements of modern data centers.
The agreement encompasses LiquidStack’s global workforce, as well as its manufacturing, engineering, and research operations in Texas and Hong Kong. Upon completion of the transaction, LiquidStack will operate within the Commercial HVAC business unit of Trane Technologies in the Americas segment. This integration will facilitate the scaling of LiquidStack’s expertise and technology throughout Trane’s global operations.
Holly Paeper, President of Commercial HVAC Americas at Trane Technologies, emphasized the importance of this acquisition. She noted that rising chip-level power and heat densities are redefining thermal management requirements. Customers now demand integrated cooling solutions that scale from the central plant to the chip. These evolving requirements reflect broader data center cooling trends reshaping infrastructure investment priorities across global markets. Paeper highlighted that LiquidStack’s direct-to-chip and immersion cooling capabilities, combined with Trane’s systems expertise, will deliver future-ready solutions across the entire data center ecosystem.
LiquidStack’s co-founder and CEO, Joe Capes, will join Trane Technologies in a leadership role. He expressed excitement about the acquisition, stating that LiquidStack has always been on a mission to deliver the most advanced and sustainable cooling solutions. By joining Trane Technologies, Capes believes the company can accelerate its mission with greater resources, scale, and global reach. He added that the partnership will enable LiquidStack to power next-generation AI workloads in the most demanding environments.
The transaction is expected to close in early 2026, subject to standard closing conditions. Financial terms were not disclosed. This acquisition follows Trane Technologies’ proven model of adding leading technologies that enhance its core businesses. Recently, the company also announced its acquisition of Stellar Energy, which is expected to close in the first quarter of 2026. Together, these moves highlight Trane Technologies’ strategy of strengthening its portfolio with innovative solutions that deliver strong returns over time.
Trane Technologies is recognized globally as a climate innovator. Through its brands Trane and Thermo King, the company provides efficient and sustainable climate solutions for buildings, homes, and transportation.
