Trane Technologies to Acquire Stellar Energy Digital Business

Key Terms

liquid-to-chip technical

Liquid-to-chip describes technology that takes a fluid sample (like blood, saliva, or environmental water) and moves it onto a tiny electronic or microfluidic chip for automated testing and measurement. Investors care because it shrinks and speeds up lab work — like turning a full kitchen into a compact countertop appliance — enabling faster results, lower costs, and portable or high-volume testing that can open new markets and improve margins.

modular data center solutions technical

Modular data center solutions are prefabricated, self-contained units that pack computing equipment, power, cooling and security into standardized, stackable modules—think of them like Lego or shipping containers for IT infrastructure. They matter to investors because they let businesses add or move computing capacity quickly with lower initial costs and more predictable ongoing expenses, which can speed growth, reduce risk from big one-time builds, and change capital and operating cost profiles.

OEM-agnostic technical

A product or service described as OEM-agnostic works with equipment or systems from any original manufacturer rather than depending on a single brand. For investors, that means a potentially larger customer base and less revenue risk tied to one supplier, like a universal remote that can control many TV brands instead of only one — increasing flexibility and resale potential.

Strengthens Trane Technologies’ leadership in data center thermal management solutions, while accelerating growth, innovation, and scale for Stellar Energy Digital

SWORDS, Ireland--(BUSINESS WIRE)-- Trane Technologies (NYSE: TT), a global climate innovator, announced that it has entered into a definitive agreement with Stellar Energy International, Ltd. to acquire the Stellar Energy Digital business (“Stellar Energy”), a leading provider of turnkey liquid-to-chip data center 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 centers and other complex corporate enterprises. Stellar Energy’s expertise in modular data center 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 center 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.

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.

“We look forward to welcoming the Stellar Energy Digital team as we serve the critical and fast-growing data center market as a trusted, long-term partner for holistic and sustainable thermal management solutions,” said Holly Paeper, President, Commercial HVAC Americas, Trane Technologies. “Together we will continue to deliver innovative, industry-leading thermal management solutions and services that help our respective customers achieve their growth, efficiency, and sustainability objectives.”

“This marks an exciting next chapter for Stellar Energy and our talented teams,” said Peter Gibson, Executive Chairman, Stellar Energy International, Ltd. “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. 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.”
