Sustainable Cooling Solutions for High-Performance Data Centres

Smart, sustainable water system management for energy efficient cooling in data centres.

Efficient data centre cooling is essential to keeping your IT infrastructure online, efficient, and cost-effective. At Marlowe Environmental Services, we deliver water treatment solutions designed for high-performance data centres, helping you reduce energy consumption and water usage, while preventing costly downtime.

We work with hyperscale, colocation and edge facilities across the UK, supporting both liquid-cooled and air-cooled environments. To find out more contact us .

Data Centre Cooling Systems

Sustainable water-based cooling for high-density performance

Liquid cooling is becoming the go-to solution for today’s energy-intensive data centres. Whether you operate a hyperscale facility or a smaller edge deployment, data centre water cooling offers efficient thermal management but it requires expert design and treatment to perform reliably.

We provide advanced water treatment solutions for liquid cooling systems that will support:

Optimal thermal performance
Reduce chemical consumption
Sustainability targets
Improvements in equipment life expectancy

Our team ensures your data centre water cooling system is protected from corrosion, scale, bacteria and fouling, keeping things clean, compliant, and under control.

Data Centre Cooling Tower Efficiency

Cut water use and boost performance with water recycling

Cooling towers are commonly used for large-scale data centres, as water is an extremely efficient cooling medium, using a lot less energy than air. The problem lies in the fact that cooling towers consume hundreds of thousands of litres of water per day, which is both costly and wasteful.

MES’s cooling tower bleed recovery and rainwater recycling systems will dramatically reduce water wastage, providing a return on investment in a very short timeframe:

Recover up to 70% of process water and rainwater
Save approximately £2 per cubic metre of water recovered, equating to hundreds of thousands of £s in the largest data centres.
Reduce energy usage and environmental impact
See ROI in as little as 6 months

Data centre cooling is most efficient when the water is clean. Our water recycling systems filter the purged water, removing dissolved solids, so it can be reused in the process again, improving operational certainty, prolonging assets and reducing energy bills.

Closed Loop Water Treatment for Air-Cooled Data Centres

Protect critical HVAC systems with real-time corrosion monitoring

For air-cooled facilities using closed-loop water systems, corrosion and contamination are common risks. Without ongoing monitoring, these issues can cause unexpected failures, driving up costs and downtime.

We provide real-time monitoring to track a wide range of parameters that can be indicative of corrosive conditions, such as:

pH, temperature & pressure
Inhibitor levels
Dissolved oxygen
Corrosion rates
Galvanic currents

This gives facilities managers full visibility into system health, allowing early action before problems escalate.

Real-time monitoring is a key tool in a predictive approach to maintenance, reducing unnecessary site visits and intervention. Alerts are sent remotely when changes in parameters occur, allowing FMs and maintenance teams to intervene only when needed.

This approach supports lean maintenance practices and can lead to water savings by avoiding ‘routine’ flushing.

Benefits:

Prevents corrosion and fouling
Reduces unplanned maintenance
Enhances energy efficiency
Extends system lifespan
Cuts chemical and water waste
