Carrier Expands Data Centre Cooling Portfolio with New Coolant Distribution Unit

Carrier has introduced its new Coolant Distribution Unit, developed to help European data centres meet growing cooling demands while improving energy performance, operational resilience and space utilisation. The Carrier CDU, part of Carrier’s expanding QuantumLeap™ portfolio of purpose-built data centre solutions, is engineered to support the rapid rise of liquid-cooled IT while giving operators greater control over energy use and system uptime. Carrier is part of Carrier Global Corporation (NYSE: CARR), global leader in intelligent climate and energy solutions.

As rack densities rise and operators work to achieve aggressive efficiency targets, liquid cooling is becoming an essential strategy. The new Carrier CDU enables customers to deploy liquid cooling at scale while maintaining stable operations and lowering the Total Cost of Ownership (TCO). Its advanced controls allow precise management of secondary coolant loops, helping data centres reduce pumping energy and optimise heat-removal performance across a wide range of load conditions.

The Carrier CDU’s modular heat exchangers can deliver approach temperatures as low as 2°C, compared with the more typical 4°C. This enhanced thermal performance can help operators realise up to 15% chiller energy savings, freeing more electrical capacity for IT loads rather than cooling.

“Data centre leaders across Europe are focused on increasing capacity without increasing risk,” says Charlotte Henry, CDU Product Manager at Carrier Climate Solutions Europe. “This new Carrier CDU supports that goal by giving operators greater thermal stability, more flexibility in system design and better visibility of cooling performance. The result is improved energy efficiency and smoother scalability as liquid cooling demand grows.”

Designed for reliability in mission-critical environments, the Carrier CDU features redundant pumps and power supplies that support uninterrupted cooling, even during maintenance or unexpected events. Intelligent control logic manages fluid temperatures and flow rates in real time, helping maintain optimal conditions for high-density servers while reducing energy consumption.

The unit’s simplified integration makes it easy to introduce liquid cooling into existing facilities with minimal disruption. With multiple unit sizes ranging from 1.3 to 5MW, the Carrier CDU product family gives operators the flexibility to match cooling capacity to both current and future high-density requirements. Whether supporting direct-to-chip cooling or mixed cooling environments, the system provides stable performance even under fluctuating workloads and high ambient temperatures.

“Liquid cooling adoption is accelerating, and operators want solutions that deliver both efficiency and certainty,” Charlotte Henry adds. “With this Carrier CDU, customers can integrate high-density workloads confidently, knowing their cooling system is designed to maximise uptime, efficiency and long-term value.”

The Carrier CDU also integrates with Carrier’s controls ecosystem, enabling centralised monitoring, performance optimisation and energy-management insights. This allows data centre teams to identify cooling trends, react quickly to load changes and plan capacity with confidence.

As part of Carrier’s QuantumLeap™ portfolio, the Carrier CDU strengthens a growing suite of data centre solutions engineered to help customers reduce energy costs, support sustainability goals and maintain stable operations in an increasingly demanding digital landscape.
