التحدي
A lot of scale and fouling was formed inside the heat exchangers, requiring cleaning every 3 months for compressor cooling and every 6 months for the vessel jackets. Algae could be found at the cooling tower despite the use of an RO system.
حل Merus
Three Merus Rings were installed to treat the entire cooling water system: one ahead of the cooling tower, one ahead of the compressor heat exchanger, and one at the vessel jacket inlet.
النتائج
→Scale was almost totally gone after 3 months with no extensive cleaning needed. This heat exchanger is now stable for more than 5 years. Algae was eliminated and no additional chemicals were required. ROI of this installation was about 2 months. The customer discontinued the RO system and now uses bore well water directly.
