Founded: 1915
Location: Palm Beach Gardens, Florida, US

Carrier invented modern air conditioning, and that heritage continues through its advanced data centre cooling portfolio.

The company provides a comprehensive range of air-cooled and water-cooled chillers, alongside air handling units designed for the rigours of 24/7 operation. 

Carrier has made significant strides in high-density cooling, recently expanding its liquid cooling capabilities to support the heat loads generated by modern GPU clusters. 

The company’s global service network is a major selling point for multinational operators requiring consistent support across continents.

4. Johnson Controls

CEO: Joakim Weidemanis
Founded: 1885
Location: Cork, Ireland

Johnson Controls, through its York brand, provides some of the most efficient chiller technology on the market. 

The company’s magnetic-bearing centrifugal chillers are highly prized in the data centre industry for their lack of oil and friction, which leads to lower maintenance costs and higher efficiency at part-load conditions. 

Beyond hardware, Johnson Controls is a leader in building automation. 

Its OpenBlue platform integrates HVAC data with other facility metrics, providing a single pane of glass for monitoring energy usage and thermal performance.

3. Stulz

CEOs: Jürgen Stulz & Alexander Stulz
Founded: 1947
Location: Hamburg, Germany

Stulz is one of the few providers that focuses almost exclusively on mission-critical applications. 

This dedication has made the company a trusted partner for telco and data centre operators worldwide. 

Its CyberAir range of precision cooling units is famous for its versatility, offering numerous airflow configurations to suit raised floor or non-raised floor designs. 

Stulz is also a leader in the move towards liquid cooling, offering side-car solutions and direct-to-chip technology that integrates seamlessly with existing air-cooled infrastructure.

2. Vertiv

CEO: Giordano Albertrazzi
Founded: 1965
Location: Westerville, Ohio, US

Vertiv has rapidly established itself as a pure-play digital infrastructure leader. 

The company’s HVAC solutions are built specifically for the unique demands of the data centre, ranging from room-based cooling to high-density liquid cooling for AI-ready facilities. 

The Vertiv Liebert brand remains the industry standard for precision cooling, offering unmatched reliability and efficiency. 

Vertiv stands out due to its ability to provide end-to-end thermal management, including prefabricated modular cooling units that can be deployed in weeks rather than months.
