Monitoring is a critical part of our closed-circuit water treatment services. These systems are crucial to overall HVAC performance, but they are vulnerable to corrosion and scale, in many cases leading to poor performance and high costs.
Real-time monitoring technology protects expensive HVAC assets and reduces risk by continuously monitoring the parameters that cause corrosion, allowing FMs to take a preventative approach to HVAC water treatment.
What is real-time monitoring used for?
How does real-time data inform water treatment?
The starting point of any water treatment programme is to ensure that the system is as clean as practically possible. If FMs can refer to real-time data, they can make informed and appropriate water treatment decisions based on accurate information.
Water Treatment can be designed to be specific and efficient, rather than as a knee-jerk reaction. Flushing, for example, is often undertaken as a matter of routine but it can lead to damage and unnecessary degradation. In many cases, more sustainable methods can be used, including side stream filtration and non-chemical treatments, which are less invasive and reduce chemical and water requirements.
The core principle of this approach is that cumulative data informs active service interventions. Monitoring technology tracks parameters which indicate a risk of corrosion, rather than the corrosion itself, ensuring energy use is optimised, plant life if prolonged and costs reduced.
What parameters should FMs monitor?
The most important corrosion causing parameter is Dissolved Oxygen (DO) – something that is not flagged up by sampling or corrosion coupons.
DO is the precursor to all corrosion in closed circuit water systems. If left unchecked, debris can build up in pipes and components causing a whole host of problems, including reduced performance of heat exchangers, changes in flow characteristics, leaks and general degradation of pipework and components.
