Tailored solutions to improve performance, reduce corrosion, and extend system life.

Closed-loop systems play a critical role in maintaining stable temperature control across a wide range of commercial and industrial applications. Whether circulating chilled or heated water, these systems operate under consistent pressure and flow conditions, often 24/7, making their reliability essential to overall plant performance. Because they are sealed systems, many assume they are low maintenance—but in reality, they are highly susceptible to internal issues such as corrosion, scale formation, and microbiological contamination. Left unchecked, these issues can restrict flow, reduce heat transfer efficiency, and lead to premature equipment failure. That’s why effective closed-loop water treatment isn’t optional—it’s essential. At Tandex, we develop tailored treatment programs designed around the specific materials, configurations, and operating conditions of your system to keep it running clean, efficient, and dependable.

We start by conducting a thorough assessment of your system’s water chemistry, construction materials, and day-to-day operating conditions. This initial analysis allows our technicians to gain a comprehensive understanding of the unique challenges your closed-loop system may face. Based on these findings, we design a customised water treatment program that directly addresses your system’s specific needs. Our programs typically incorporate high-performance corrosion inhibitors to prevent metal degradation, pH stabilisation agents to ensure chemical balance, and targeted microbial control solutions to minimise the risk of biofilm formation and bacterial contamination. By maintaining clean, chemically balanced water within the loop, we help safeguard critical system components from internal damage and degradation. The outcome is improved operational efficiency, extended equipment lifespan, and a significant reduction in costly unplanned maintenance or downtime.
