DATA CENTRES
As data centres face continued surging demand on account of AI, cloud computing and high-performance workloads, cooling technologies are undergoing a transformative shift.
In 2025, hybrid cooling systems – where liquid and air cooling is combined – are starting to emerge as an industry solution for balancing data centre efficiency, scalability and sustainability.
These systems have potential to offer flexibility for handling diverse workloads, from legacy equipment to high-density AI applications, while also enabling operators to futureproof their facilities.
With this in mind, Data Centre Magazine hears from Danielle Rossi about how Trane Technologies is eager to spearhead innovation with advanced liquid cooling solutions and heat recovery systems that optimise energy use and reduce environmental impact.
She explains how hybrid cooling could redefine thermal management in modern data centres.
Q. HOW IS LIQUID COOLING EVOLVING ACROSS THE DATA CENTRE INDUSTRY IN 2025?
» Liquid cooling has been around for more than 50 years, utilised in space and graphics applications. Only in the last few years have chip and compute density loads been high enough to justify, or in some cases require, using liquid cooling.
There are several different types of liquid cooling, and each has a place

in design. Recently, there has been an increase in hybrid cooling designs making each solution application specific. These hybrid designs are utilising multiple types of liquid cooling and / or air-cooling dependent on the design needs.
Q. WHAT ARE THE BENEFITS OF HYBRID COOLING? CAN THIS GIVE OPERATORS GREATER OPPORTUNITIES FOR SUSTAINABLE BUSINESS GROWTH?
» For the foreseeable future, hybrid cooling is going to be prevalent in the industry. With the increase in AI adoption, data centres will be segmented while they adjust to these new large loads and continue to require support for legacy, less dense equipment.
