OUR WORLD-CLASS LIQUID COOLING SUITES IN LONDON AND HONG KONG
CLICK HERE TO BOOK YOUR TOUR IN LONDON
Global Switch’s London Liquid Cooling Suite is the only space of its kind in Europe where all five of the major liquid cooling technologies are available to experience live and in action, some for the very first time. The twophase direct-to-chip system is the first operational demonstration outside of the US, the single-phase immersion tank is the first of its kind in Europe, and the two-phase immersion tank utilises an experimental fluid never before implemented outside of the US. Connected to an operational data centre and with dummy heating loads, the technology demonstrates as close to true-to-life operations as possible, delivered in collaboration with Global Switch’s selected technology partners.

Global Switch was the first to bring liquid-cooled capacity to Hong Kong, delivering for the city’s booming AI sector. These latest liquid cooling technologies are available to view today at Global Switch’s Tseung Kwan O data centre, the largest carrier and cloud neutral facility in the city, located in the heart of the city’s financial and business district. The full suite of liquid cooling technologies, available to Global Switch customers now, are delivered in collaboration with Global Switch’s technology partners.
FREQUENTLY ASKED QUESTIONS
What is liquid cooling?
Put simply, liquid cooling is a method of removing heat from IT equipment using liquid-based cooling technologies rather than relying solely on air cooling.
What is direct-to-chip liquid cooling?
Direct-to-chip liquid cooling delivers coolant directly to the hottest components within a server, such as CPUs and GPUs. Using cooling plates attached to the chips, heat is captured at the source and transferred away more efficiently than traditional air cooling.
What liquid cooling technologies are available in Global Switch data centres?
Global Switch supports a wide range of advanced liquid cooling technologies, enabling customers to deploy high‑density, AI‑ready infrastructure.
These include:
- Single-phase and two‑phase immersion cooling solutions
- Direct‑to‑chip liquid cooling, including both single-phase and two‑phase systems
- Rear‑door heat exchangers and integrated cooling systems
- Heat transfer fluids and supporting cooling infrastructure, including pipework and coolant distribution units
Global Switch works with leading technology providers such as Vertiv, Accelsius, Supermicro, Giga Computing and LiquidStack to deliver flexible, high-performance cooling environments.
Does liquid cooling support AI workloads?
AI workloads generate significantly more heat than traditional IT environments due to their intensive processing requirements and high GPU utilisation. Liquid cooling removes heat more efficiently at the source, helping to support the higher power densities, performance demands and scalability required by modern computing infrastructure.
Is liquid cooling more energy efficient than air cooling?
Yes. Liquid cooling can improve cooling efficiency in high-density environments, helping reduce energy consumption associated with heat management and supporting improved PUE performance. As part of Global Switch’s wider ESG and sustainability commitments, liquid cooling technologies help support the delivery of efficient, future-ready infrastructure capable of meeting growing demand for high-performance computing while minimising environmental impact wherever possible.
