Trane Technologies is set to acquire the digital business of Stellar Energy, a leading provider of turnkey liquid-to-chip data centre cooling solutions.
Headquartered in Jacksonville, Florida, Stellar Energy designs and builds modular cooling plants, central utility plants and coolant distribution units for liquid-cooled data centres and other complex corporate enterprises.
Stellar Energy’s expertise in modular data centre solutions is well-positioned to address the growing demand for pre-fabricated cooling systems and other critical equipment, which reduce supply chain constraints and enable rapid, scalable deployment.
The acquisition will include Stellar Energy’s existing Digital business operations, including two assembly operations in Jacksonville, Florida, and its highly skilled team of approximately 700 employees.
The acquisition further bolsters Trane Technologies’ leadership and capabilities in the high growth data centre thermal management solutions market and creates opportunities to grow and scale the Stellar Energy business and leverage their expertise in modular design, engineering and assembly across numerous core commercial verticals.
Trane Technologies chief strategy officer, Karin De Bondt, said the data centre ecosystem is growing rapidly and evolving toward more agile, sustainable solutions, which is where Stellar Energy excels with leading co-engineered, modular solutions and a proven business model.
“We are delighted to welcome the talented Stellar Energy Digital team as we jointly expand our leadership and commitment to this critical sector and other commercial applications,” De Bondt said.
“Together we are well-positioned to expand our capabilities and offerings and create long-term customer and shareholder value.”
Upon completion, Stellar Energy’s Digital business will operate within the Commercial HVAC business unit of the Trane Technologies Americas segment, retaining its brand, OEM-agnostic direct-to-customer sales model, and existing customer relationships.
Stellar Energy International executive chair, Peter Gibson, said the deal marks an exciting next chapter for Stellar Energy and its talented teams.
“Transitioning the Digital business to Trane Technologies positions the business for significant growth and continued excellence, while our existing customers will benefit from expanded services and resources,” Gibson said.
“We’ve worked closely and successfully with Trane Technologies for many years, and I am confident Stellar Energy’s powerful combination of bespoke solutions and scalable expertise will thrive within Trane Technologies.”
This bolt-on acquisition follows Trane Technologies’ proven model of adding leading technologies that augment its core business and scaling them to deliver strong returns over time.
The transaction is expected to be completed in early 2026.
