Trane Technologies Opens Pre-Orders for LiquidStack CDU 2.X Coolant Unit, Shipping Q2 2027

Trane Technologies has opened pre-orders for the LiquidStack CDU 2.X, a coolant distribution unit the company says can serve a range of AI hardware from a single design, with shipments scheduled to begin in the second quarter of 2027.

The company announced the platform on September 29, 2026, at the Yotta 2026 event in Swords, Ireland.

Availability and Ordering

The LiquidStack CDU 2.X is available for pre-order now, according to Trane Technologies. The company says shipments will begin in the second quarter of 2027. Further details are published on the LiquidStack website at liquidstack.com/coolant-distribution-unit-2x.

Trane Technologies, which trades on the New York Stock Exchange under the ticker TT and describes itself as a global climate innovator, positions LiquidStack as one of its brands. The release characterizes LiquidStack as focused on advanced liquid cooling for scalable AI infrastructure.

What the Platform Is Meant to Solve

The company describes the CDU 2.X as an architecture-agnostic coolant distribution unit designed to deliver the cooling performance and deployment flexibility required by rapidly evolving AI infrastructure.

According to the announcement, the platform is intended to help reduce redesign risk and simplify deployment for data center operators, and it reflects Trane Technologies' continued investment in advanced thermal management for high-density data center environments.

The announcement frames flexibility as a central requirement for AI, high-performance computing and hyperscale data centers as the GPU landscape continues to shift and accelerate. Trane Technologies says the CDU 2.X uses a single CDU design that supports today's industry-leading AI hardware alongside emerging solutions.

Scott Smith, General Manager of LiquidStack at Trane Technologies, said in the release that operators need cooling infrastructure that can adapt as GPU platforms and rack densities evolve.

He said the CDU 2.X combines the performance and flexibility customers need today with headroom for what comes next, allowing them to configure cooling around their facility and deployment strategy rather than designing the facility around the CDU.

Performance and Hardware Support

On performance, Trane Technologies states that the unit offers flow capability of up to 3750 liters per minute at 3.5 bar. The company says it is designed to meet the cooling needs of current GPU platforms while leaving headroom for next-generation platforms as rack densities increase.

The company adds that the unit is designed to support next-generation GPU platforms, including NVIDIA Vera Rubin and beyond, and cites this as the source of the platform's performance headroom for next-generation AI.

It also says the platform is built around a common CDU architecture intended to support multiple current and emerging AI silicon platforms.

Electrical and Deployment Design

Deployment simplicity is one of the features Trane Technologies emphasizes. The company says an ultra-low-harmonics variable frequency drive, or VFD, architecture is designed to address harmonic distortion at the source.

According to the release, this reduces the need for additional power-quality components and simplifies system architecture and deployment. The platform also offers a flexible power architecture, the company says. Dual-feed A/B and automatic transfer switch options let operators configure the CDU 2.X around different facility resiliency requirements.

Flexible control valve, power-feed and redundancy options allow the unit to be configured around different facility and deployment architectures, per the announcement. On layout, Trane Technologies describes a flexible distribution architecture.

End-of-row and rack-adjacent deployment support is intended to give operators greater flexibility to address increasing rack densities and future architectures.

Efficiency Characteristics

The release describes the platform as designed for high-efficiency operation. Lower approach temperatures and facility inlet temperatures up to 45°C support efficient liquid cooling system architectures, according to the company.

Follows GigaModular Rollout

The CDU 2.X announcement comes on the heels of the commercial availability of the LiquidStack GigaModular CDU platform, which the company says now has an expanded capacity of 14 MW.

Trane Technologies states that its liquid cooling portfolio, including LiquidStack solutions, gives data center operators greater flexibility in how they deploy and scale next-generation liquid cooling infrastructure.

Company Background

LiquidStack is described in the release as a global leader in advanced liquid cooling for scalable AI infrastructure, delivering future-ready cooling architectures designed for next-generation GPU platforms.

The company says its solutions are built to support hyperscale AI growth and enable operators to deploy, scale and optimize high-density AI infrastructure with confidence. Trane Technologies describes itself as a global climate innovator.

Through its strategic brands Trane and Thermo King, and its environmentally responsible portfolio of products and services, the company says it brings efficient and sustainable climate solutions to buildings, homes and transportation.

Forward-Looking Statements

The announcement includes a forward-looking statements disclaimer covering the company's product and service innovations in coolant deployment systems for AI data centers, as well as the anticipated marketability and operational benefits of those innovations.

Trane Technologies notes that these statements are based on current expectations and are subject to risks and uncertainties that could cause actual results to differ materially.

The company points readers to its Form 10-K for the year ended December 31, 2025, and its subsequent reports on Form 10-Q and other SEC filings for factors that could cause such differences.

It adds that new risks and uncertainties arise from time to time, that it is impossible to predict these events or how they may affect the company, and that it assumes no obligation to update the forward
