Water quality within a closed heating and chilled water system should remain stable over time. When it changes unexpectedly, it is often a clear indication that the system has been compromised and requires immediate investigation.
In real-world operation, these are not theoretical risks – they are live events that our monitoring systems actively detect and escalate.
A recent example involved cross-contamination of water in a CHW system due to negligence – detected by an abrupt and unexpected change in dissolved oxygen, conductivity and pH. Since the Hevasure Aquila-2 system captures multiple parameters and applies a date/time stamp against all readings, this allowed the building owner to identify exactly when the contamination occurred and identify the guilty party.
What made this particularly critical was the speed of change. These were not gradual variations associated with normal system fluctuations, but sudden and large deviations that signalled an external influence had compromised water quality. In effect this was like a ‘smoking gun’, and the contractor responsible had no hiding place. They agreed to flush and re-dose the system at their own expense, returning the water to an acceptable level of quality.
Without continuous monitoring in place, this type of event would typically only be identified during routine sampling, and the time of the cross-contamination would not have been deduced. Perhaps more importantly, corrosion and system degradation would almost certainly have begun.
With over 12 years of experience and 200 installations across the UK, our Aquila system has repeatedly proven its ability to detect these sudden and critical changes in real operating environments.
Now in its fourth generation, it provides not just data, but immediate insight into system behaviour – enabling fast, informed intervention when it matters most.
