Initially thought to be caused by slime and algae, observation under an optical microscope revealed that filamentous fibers, which were not visible to the naked eye, had detached from the cooling tower components. Case 2: Hole in the Refrigeration Unit Condenser Overview - Issue: A problem occurred where a hole developed in the condenser of the refrigeration unit, prompting a water quality test to determine the cause. - Solution: An analysis of the cooling water was conducted to investigate the cause of corrosion in the condenser, revealing a high concentration of sulfate ions. It was determined that flue gas (sulfur dioxide) from the incinerator had dissolved in the cooling water, leading to the issue. To resolve the problem, measures were taken to extend the chimney to prevent any impact on the cooling tower.	For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Changes in water quality are a red flag for equipment troubles!

overview

Here are two cases where issues occurred despite acceptable water quality. **Case 1: Abnormal Shutdown of Cooling Tower** **Overview** - **Issue**: The cooling tower in an office building experienced an abnormal shutdown, and upon investigation, foreign substances were found attached to the strainer. - **Solution**: The strainer for the cooling water was clogged with foreign substances, causing the equipment to stop. Initially thought to be caused by slime and algae, observation under an optical microscope revealed that filamentous fibers, which were not visible to the naked eye, had detached from the cooling tower components. **Case 2: Hole in the Refrigeration Unit Condenser** **Overview** - **Issue**: A problem occurred where a hole developed in the condenser of the refrigeration unit, prompting a water quality test to determine the cause. - **Solution**: An analysis of the cooling water was conducted to investigate the cause of corrosion in the condenser, revealing a high concentration of sulfate ions.
