Navigating the Shift in Corrosion Monitoring Techniques for HVAC Systems

Corrosion Challenges in HVAC Systems

Corrosion in closed water systems presents significant challenges in HVAC management. Traditional methods like water sampling, while useful, have limitations that can miss critical signs of corrosion. The industry is now embracing more sophisticated, real-time monitoring solutions. This blog delves into this crucial shift.

Traditional Corrosion Detection vs. Advanced Monitoring

Traditionally, engineers relied on water sampling for corrosion detection. This method, however, only offers a limited view of a snap shot in time, often missing key indicators like dissolved oxygen, a crucial factor in corrosion development. These limitations highlight the need for more comprehensive monitoring solutions. 

Advancements in Real-Time Corrosion Monitoring

The introduction of real-time monitoring technologies, such as Hevasure’s system, marks a significant advancement. These systems monitor various parameters continuously, providing an in-depth, real-time view of the system’s health. This approach not only allows for early detection of potential issues but also minimizes the need for physical inspections. Learn more about Hevasure’s technology on their official website.

Case Study: Resolving Corrosion at Telephone House, London

Telephone House in London showcases the effectiveness of real-time monitoring. Persistent radiator leaks were traced back to oxygen ingress, identified through Hevasure’s monitoring. This case study demonstrates the potential of real-time monitoring in diagnosing and resolving hidden issues that traditional methods might miss. The full case study is available here.

The Future Impact of Real-Time Monitoring on Corrosion Prevention

The industry’s shift towards real-time monitoring is gaining recognition, as evidenced in updated guides like BSRIA BG29 2020 and BG50 2021, which cover pre-commissioning cleaning and ongoing water treatment respectively. We have responded by developing intelligent water monitoring packages that help Facilities Managers and Building Owners meet BSRIA’s guidelines, while reducing the risk of corrosion-related breakdown and providing transparency in regards to the real-time condition of crucial HVAC systems.

For more insights, refer to BG29 2020’s guidelines on BSRIA’s website.

Conclusion: Embracing the Future of Corrosion Monitoring in HVAC Systems

The evolution from traditional to real-time corrosion monitoring represents a significant step forward for HVAC system management. This proactive approach allows engineers to stay ahead of potential issues, ensuring system longevity and efficiency.
