Matching Sustainability With Operational Certainty
Steve Dawson, Product Manager, Closed Systems for Guardian Water Treatment discusses why preventing HVAC corrosion should be a priority for sustainability as well as operational reasons.
HVAC corrosion can be a headache for facilities managers (FMs), a problem that leads to system breakdown and expensive repairs. In closed systems in particular, corrosion often goes unseen until it is too late, leaving FMs fitting the bill for problems that are not always their fault.
Apart from being costly if left to go unchecked, corrosion can also negatively impact sustainability goals by causing system inefficiencies. The treatments for corrosion – chemical usage and flushing large volumes of water through pipework – are also potentially damaging to the environment. Balancing corrosion prevention with keeping systems in good working order can be a challenge.
Corrosion’s Impact On Efficiency
Water-based HVAC systems are essential for maintaining comfortable and productive environment, yet these systems often operate under conditions that make them vulnerable to inefficiencies. Corrosion,
scale formation, and microbial
fouling are common culprits that compromise heat transfer, leading to higher energy usage. Furthermore, corrosion byproducts can contaminate water, increasing the burden on water treatment processes.
Improving the sustainability of these systems starts with a proactive approach to system health. Corrosion, for example, not only degrades pipes, valves, and heat exchangers but also contributes to leaks. If left unchecked, these issues will lead to operational downtime,
leaving FMs vulnerable to liability and subsequent fines. 38 fmuk
