Cooling Tower Optimization in a PVC Film Manufacturing Plant, East Java
Industry
Manufacturing
Challenge
The PVC film manufacturing plant faced persistent foaming and operational inefficiencies in its 400 HRT cooling tower due to the incompatibility of a previous chemical treatment with local water conditions. This resulted in poor heat transfer, excessive water consumption, increased risk of mineral scale and corrosion, and frequent system downtime. The instability of the former treatment under the plant’s operational temperatures further threatened equipment reliability and process consistency.
Results
After implementing Hydro 424 at a controlled daily dosage and incorporating rigorous monitoring protocols, the plant established stable, foam-free cooling tower operation. The advanced formulation of Hydro 424 delivered robust scale and corrosion inhibition, yielding measurable improvements: 30% downtime reduction, 25% lower maintenance costs, and a 15% increase in heat transfer efficiency. The plant also benefited from increased customer satisfaction and safer, more reliable system performance.
Key Product
Product one
After switching to Hydro 424, our cooling tower performance improved dramatically. Previously, we struggled with excessive foaming and unstable chemical treatment, which caused repeated maintenance and reduced cooling efficiency. With Hydro 424, the system now runs clean, stable, and completely foam-free. Scale and corrosion are fully under control, and our heat exchangers operate much more efficiently.We’ve seen a noticeable reduction in downtime and maintenance costs. Overall, we are extremely satisfied with the results. Hydro 424 has proven to be a reliable and effective solution for our cooling system.

About your Customer
A leading PVC film manufacturing plant based in East Java, operating a 400 HRT cooling tower with a circulation rate of 350 m³/hour. The facility is committed to maintaining high operational efficiency and reliability in its cooling systems.The Challenge
The PVC film manufacturing plant in East Java encountered substantial operational setbacks in its cooling tower system. Persistent foaming from the previous chemical treatment compromised heat transfer efficiency and increased water consumption. Additionally, the plant faced mounting risks of mineral scale buildup and corrosion, leading to frequent downtime for cleaning and repairs. The instability of the prior treatment at operational temperatures undermined both equipment protection and process reliability, threatening to impact overall plant productivity.
The Solution
To address these challenges, the plant evaluated available chemical treatment options and selected Hydro 424, a non-foaming, corrosion and scale inhibitor engineered for industrial cooling systems. The choice was driven by its proven stability, compatibility with local water quality, and safety profile. The plant implemented a daily dosage of 200 ppm, closely monitored system parameters such as pH and conductivity, and adhered to rigorous operational protocols. According to the Plant Manager, "Hydro 424 worked effectively as an anti-scale and anti-corrosion agent with no foaming issues." This transition enabled the plant to restore stable and efficient cooling tower operation with minimal disruption.
The Results
Following the adoption of Hydro 424, the plant achieved significant performance gains. Foam-related issues were eliminated, resulting in uninterrupted heat transfer and reduced water usage. Technical monitoring confirmed effective scale and corrosion control, which translated into a 30% reduction in downtime, 25% savings in maintenance costs, and a 15% boost in heat transfer efficiency. Equipment longevity increased and operational safety improved, as Hydro 424 is classified as non-hazardous. The plant’s experience demonstrates the critical importance of selecting robust, technically compatible water treatment solutions for sustained industrial reliability.
