KEEP CRITICAL SITES SAFE WITH SECURE MONITORING
The best way owners of mission critical sites can mitigate against high cooling costs is by monitoring their closed-circuit water systems in real-time, 24/7. Changes in key parameters that indicate corrosive conditions, such as dissolved oxygen levels, loss of inhibitor or unstable pH, are flagged up immediately, allowing problems to be nipped in the bud.
Up until recently, however, this seemed at odds with security concerns. Collection of data from building services coupled with two-way communication with the outside world can leave secure environments vulnerable to cyber-attack, with remote monitoring systems providing an ‘in’ for hackers where data is processed on the cloud or if third-party companies have access for remote maintenance.
WHY MONITOR? Critical cooling: In data centres, for example our
increasing reliance on processing-intensive applications puts extra pressure on HVAC. Racks of servers produce vast amounts of heat and performance will be compromised if cooling is inefficient.
In the event of prolonged exposure, servers will shut down completely to protect themselves, causing unacceptable downtime. Real-time monitoring of critical HVAC helps to mitigate against this risk by making sure cooling systems are reliable and efficient.
Critical comfort: And, let’s not forget HVAC’s important role in occupant comfort - in sites such as hospitals, prisons and office blocks, the failure of these systems can lead to a building becoming uninhabitable in both winter and summer months.
SECURE HVAC MONITORING Thanks to recent developments in secure building
automation, even high-risk environments can reap the benefits of real-time HVAC monitoring, leading to more efficient cooling, fewer service interventions and more reliable operations. In-built logic provides intelligent diagnosis, without the use of cloud storage. All data processing is done locally, with data, alarms and messaging made available to a BMS via a secure BACnet interface.
SAFE HVAC MONITORING Apart from keeping HVAC operational, constant,
real-time monitoring also helps to cut site visits. Water sampling and analysis can be significantly

HVAC systems are a huge drain on resources, but essential for overall performance and operation, particularly in mission critical sites where downtime is not an option. Steve Munn, MD for Hevasure, discusses the benefits of real time condition monitoring using the latest data collection and analysis tools, including options for sites that can’t afford the risk of cyber-attack.
Hevasure Aquila-s for closed-circuit water systems in secure sites has a number of benefits, including:
● Extended life of HVAC plant – closed-circuit HVAC systems monitored throughout their life will last longer and breakdown less.
● Increased ROI - over a period of 10 years, 24/7 monitoring can save tens of thousands of pounds across the board, improving energy efficiency, reducing water treatment costs and importantly for building owners, preventing catastrophic failure.
● Downtime prevention – overheating can cause operational failures. Secure real-time monitoring keeps corrosive conditions at bay and allows HVAC systems to meet their potential, ensuring buildings are reliable and safe.
● Leaner maintenance practices – with real-time monitoring, engineers are alerted to issues that need attention before damage occurs, rather than having to continually visit sites to check on key measures.
● Reduced energy requirements – preventing corrosion in closed-circuit systems leads to efficient heat transfer, leading to lower energy costs.
● Improved accountability – real-time data provides transparency across the board, from construction to handover, tenants and ongoing facilities management. The ability to pin-point and track disruption and resolution provides peace-of- mind to owners and ensures that misplaced blame is avoided.
reduced which, during the height of the pandemic, had a particular benefit in the fight against COVID-19, helping to reduce travel and human interactions.
Overall, for secure sites where contractor clearance is essential, by reducing uncertainty, off-plan call-outs should also cut costs, paperwork and risk.
