LiquidStack's GigaModular cooling platform, on sale since May 2026, scales to 14 MW

On 21 May 2026 LiquidStack, the liquid-cooling company Trane Technologies bought in March 2026, announced that its GigaModular coolant distribution unit (CDU) platform was commercially available, in multi-megawatt building blocks reaching as much as 14 MW.

The announcement

LiquidStack, based in Carrollton, Texas, makes liquid cooling for data centres. In its release it describes GigaModular as a pay-as-you-grow design: operators install multi-megawatt blocks and add more as their needs rise, with one central control system running the whole installation. The company says the platform is built to meet NVIDIA's Vera Rubin specifications and supports the heat loads of both off-the-shelf merchant chips and hyperscalers' own custom chips, over a range of application temperatures.

Joe Capes, a Trane Technologies vice president who serves as LiquidStack's general manager, said in the release that the approach lets operators expand cooling in phases that follow AI compute demand, without large infrastructure redesigns or over-provisioning up front. He also said the central controls simplify operations.

LiquidStack first announced GigaModular in June 2025. According to the company, it has since completed integration of multiple modules into one system and testing at full load for deployments of up to 14 MW; it has also achieved ETL certification. LiquidStack adds that early customer orders have come in. These test, certification and demand statements are the company's own.

Ownership

Trane Technologies, whose brands include Trane and Thermo King, announced on 3 March 2026 that it had completed its acquisition of LiquidStack, a deal first announced on 10 February 2026. In that announcement Holly Paeper, president of Commercial HVAC Americas at Trane Technologies, said that pairing Trane's expertise in thermal management with LiquidStack's immersion, direct-to-chip and other high-density liquid cooling would put the company in a position to offer one of the broadest ranges of thermal management products on the market.

Related deal in the sector

A second thermal acquisition closed in the same month. In its quarterly filing for the period ended 31 March 2026, Eaton says it acquired Boyd Thermal on 12 March 2026 for $9.55 billion, a figure stated net of cash acquired. The filing describes Boyd Thermal as a US-based company making thermal parts, systems and rugged equipment for data centres, aerospace and other end markets, with more than 6,000 staff and factories in North America, Europe and Asia. Eaton reports Boyd Thermal within its Electrical Global segment.

Trade show plans

In the 21 May release, LiquidStack said it planned to exhibit the platform, with live virtual-reality demonstrations, at booth 109 of Datacloud Global Congress, set for 2 to 4 June 2026 at the Palais des Festivals in Cannes, France.
