Trane Technologies (TT) has signed a definitive agreement to acquire the digital business division of Stellar Energy International, Ltd. If you're wondering what that means in plain English, Trane is buying the part of Stellar Energy that makes sophisticated cooling systems for data centers—specifically the kind that use liquid cooling delivered directly to computer chips.

Financial terms weren't disclosed, but here's what we do know: Once the deal closes, Stellar Energy Digital will become part of Trane's Commercial HVAC Americas segment. The acquisition brings two assembly plants in Jacksonville, Florida, and roughly 700 employees into Trane's orbit.

Why This Makes Sense

The acquisition expands Trane's presence in commercial HVAC while letting Stellar Energy's unit keep its brand name, its OEM-agnostic sales model, and its existing customer relationships. That's a smart move—Trane gets the technology and operational footprint without disrupting what's already working.

The bigger picture here is about data centers. They're multiplying fast, and they're getting hotter as computing power intensifies. Trane is positioning itself to capitalize on that trend with modular cooling solutions that can scale quickly.

"The data center 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," said Karin De Bondt, Chief Strategy Officer at Trane Technologies.

The deal is expected to close in early 2026, subject to regulatory approvals and customary closing conditions. It fits neatly into Trane's broader playbook of integrating complementary technologies to strengthen its core business.

For context, Trane Technologies reported a cash balance of $1.126 billion as of September 30, 2025.
