Chemical Cleaning & Flushing is a specialized process carried out to remove construction debris, rust, oil, grease, scale, and other contaminants from chilled water and HVAC piping networks. This process ensures that the system is thoroughly cleaned prior to commissioning, improving water quality, heat transfer efficiency, and overall system performance. The procedure typically includes system isolation, circulation of approved chemical cleaning agents, controlled flushing with clean water, and neutralization as required. All activities are performed in accordance with international standards and manufacturer recommendations to protect system components and extend equipment service life. Chemical Cleaning & Flushing helps prevent corrosion, fouling, and premature equipment failure, ensuring reliable and efficient operation of chillers, pumps, valves, and heat exchangers.
