Chiller System Fluid Testing

At Newsome, we understand that the performance of your chiller or HVAC system depends not only on the quality of the equipment but also on the condition of the fluid circulating within it. While the focus is often on the visible components of the system, the fluid inside can be just as important—if not more so—in determining the overall efficiency, longevity, and reliability of your process.

Water and glycol-based heat transfer fluids are essential to closed-loop cooling systems. However, over time these fluids can deteriorate or become contaminated due to chemical reactions, exposure to oxygen, the introduction of bacteria, or incorrect top-up procedures. These changes often go unnoticed until performance begins to decline, corrosion occurs, or breakdowns happen. That’s why regular monitoring, testing, and treatment of system fluid is essential—not only to prevent failure but also to maintain optimal thermal transfer and system efficiency.

Suitable for both new and existing systems

Newsome’s water treatment service is designed to manage and maintain the quality of the heat transfer fluids within your system. This service is suitable for both new and existing systems and plays a vital role in preventative chiller maintenance strategies. By evaluating the chemical composition of the fluid, we can help clients identify early signs of degradation, imbalance, or contamination before they result in serious damage or loss of efficiency. We begin by taking fluid samples directly from your system, which are then sent to a trusted independent laboratory for full analysis. Using an independent lab ensures results are impartial, scientifically robust, and free from internal bias. It also gives our clients confidence in the data they receive, with detailed laboratory reports that are clearly presented and easy to interpret. This approach provides not just transparency, but also the reassurance that your system’s performance is being assessed to the highest industry standards.

Wide range of performance indicators

The laboratory analysis covers a wide range of performance indicators, including pH levels, glycol concentration, electrical conductivity, turbidity (fluid clarity), and the presence of metals such as iron or other contaminants. These parameters offer valuable insight into the internal condition of your system, allowing our engineers to detect the early stages of corrosion, microbial growth, scaling, or fluid degradation.

Once the results are received, our experienced team reviews the findings and develops a tailored action plan. This may include adjusting the glycol concentration, dosing biocides to control microbial growth, adding corrosion inhibitors, or carrying out a full system flush if the fluid has been significantly compromised. All of these services can be provided in-house by Newsome’s engineering and service teams, ensuring that corrective action is implemented quickly and effectively.

In cases where physical contamination is present—such as suspended solids, corrosion debris or scale—Newsome may recommend side stream filtration as part of the treatment strategy. Side stream filtration involves diverting a portion of the circulating fluid through a dedicated filter unit to continuously remove particulates from the system. Over time, this process helps maintain fluid cleanliness, improve energy efficiency, and reduce the risk of future blockages or equipment fouling.

This filtration can be added to an existing system with minimal disruption and provides continuous protection against common forms of contamination. In many cases, systems that include filtration from the outset experience fewer performance issues and require less intervention over time.

More than just a reactive measure

Water treatment is more than just a reactive measure—it is a proactive service that supports long-term system health. Maintaining clean, chemically balanced fluid within your chiller or cooling system helps reduce energy consumption, improve thermal transfer, and extend the operational life of pumps, heat exchangers, and other vital components. It also plays a key role in minimising unplanned downtime and controlling maintenance costs over the system’s lifecycle.

As part of our service offering, Newsome can incorporate fluid testing and water treatment into a wider planned preventative maintenance schedule. This means we monitor the condition of your system over time, rather than simply reacting when things go wrong. Regular testing provides trend data, allowing you to anticipate maintenance needs and avoid disruption to your operations.

Whether you’re running a food processing facility, pharmaceutical plant, manufacturing site or data centre, maintaining the health of your cooling system fluids is critical to keeping your operations efficient and reliable. Newsome’s water treatment services are available to clients across the UK and can be adapted to suit both small and large-scale systems.
