Data centres generate significant amounts of heat, and uncontrolled temperature rise can lead to downtime, equipment damage, and reduced system efficiency. Traditionally, air cooling has been the default method, but modern high-density server environments require more advanced solutions.

Using liquid cooling and immersion cooling technologies supported by Global Heat Transfer’s specialist fluids provides:

• Superior heat removal compared to air cooling

• Stable operating temperatures across high workloads

• Extended hardware lifespan through reduced thermal stress

• Energy efficiency gains supporting ESG and sustainability targets

Immersion cooling is rapidly becoming a preferred solution for data centre operators looking to reduce energy costs, improve reliability, and meet growing sustainability targets. Unlike traditional air cooling systems, which struggle to manage the heat generated by high-density servers and modern computing workloads, immersion cooling submerges IT equipment directly in a specially formulated dielectric cooling fluid.

This method delivers several key advantages:

• Superior heat removal efficiency – Liquid absorbs and transfers heat far more effectively than air, enabling stable operating temperatures even in high-performance computing (HPC) and AI-driven environments.
• Reduced energy consumption – By lowering or even eliminating the need for power-hungry fans and chillers, immersion cooling can cut data centre energy use significantly, directly improving PUE (Power Usage Effectiveness).
• Extended hardware lifespan – Consistent thermal management minimises the stress of heat fluctuations, helping servers and electronic components last longer with fewer failures.
• Lower operational costs – Improved thermal performance translates into reduced cooling expenses, maximised uptime, and better long-term ROI.
• Sustainability benefits – Immersion cooling supports green data centre initiatives by reducing carbon footprint, enabling heat reuse, and improving the overall efficiency of data centre thermal management.

Immersion cooling provides a scalable, future-ready solution that enhances both performance and sustainability.

Our fluids are designed for use in a wide range of applications, including:

• Immersion cooling systems for high-performance computing

• Direct-to-chip cooling in servers

• Coolant circulation in modular data centres

• Chiller and HVAC systems supporting server halls

• Battery cooling in UPS systems

Switching from traditional air cooling to advanced data centre cooling fluids helps operators cut energy use, lower costs, and meet ESG targets. Efficient immersion cooling fluids and dielectric fluids deliver reliable performance while supporting greener operations.

Reducing Energy Consumption

Cooling accounts for up to 40% of data centre energy use. Liquid cooling fluids transfer heat more effectively than air, reducing reliance on chillers and fans. This improves PUE (Power Usage Effectiveness) and lowers both operational costs and carbon footprint.

Recovering and Reusing Waste Heat

With immersion cooling systems, data centres can capture and reuse waste heat. This recovered energy can:

• Feed district heating networks

• Support nearby commercial or industrial facilities

• Reduce overall wasted energy

Extending Hardware and Fluid Lifespan

Dielectric fluids provide stable, non-conductive cooling that minimises thermal stress. Benefits include:

• Longer server and component life

• Reduced e-waste from premature failures

• Fewer fluid changes through effective fluid management

Supporting ESG and Green IT Goals

Using sustainable data centre cooling fluids enables operators to:

• Cut emissions and improve sustainability reporting

• Comply with tightening environmental regulations

• Align with global green data centre initiatives

With more than 30 years of expertise in thermal fluid management, Global Heat Transfer not only supplies the right fluid but also provides ongoing fluid lifecycle support.

Our services for data centres include:

• Fluid selection advice based on cooling system design

• Laboratory analysis of fluid condition to extend service life

• On-site technical support for installation and maintenance

• Sustainability and disposal management, reducing environmental impact

If your system and fluid are not properly maintained or checked regularly, they can be affected.

Suppose routine representative fluid analysis shows the fluid has degraded. In that case, it must be diluted or completely flushed from the system and replaced, which causes expensive downtime and additional capital expenditure, both of which could be avoided with a proactive and preventative maintenance programme.

You can extend the life of your cooling centre fluid with help from Global Heat Transfer’s preventative maintenance programme, Thermocare. Taking samples every quarter allows you to spot any changes in the fluid and react, before it impacts system efficiency.

To get a representative sample, manufacturers must take a hot, closed sample. This is the only way to understand the condition of the fluid when it is moving around the system.

Global Heat Transfer supplies a wide range of cooling fluids suitable for electronic and data centre applications, including:

• Dielectric Fluids (non-conductive, safe for immersion cooling)

• Low-viscosity synthetic fluids for efficient circulation

• Specialty coolants designed for stability across wide temperature ranges

• Environmentally considerate formulations for reduced impact and improved recyclability

We understand the critical uptime requirements of the data centre industry. That’s why we ensure:

• Rapid response times

• Short lead-time delivery from UK and global depots

• Ongoing technical support tailored to data centre operations

• Expertise in both legacy cooling systems and next-generation immersion technologies

By working with GHT, data centre operators can improve reliability, lower energy costs, and operate more sustainably.
