Pipeline flushing is essential for maintaining the performance of chilled water networks, especially in large-scale District Cooling (DC) systems. Over time, contaminants such as rust, sludge, algae and sand accumulate inside closed-loop pipes, reducing heat transfer and system efficiency.

Flushing is typically required both:

• Post-installation, to remove debris from newly laid lines
• During regular maintenance, as part of utility providers’ long-term performance strategies.

WJ uses flushing pumps, filters and, where necessary, chemical treatments to restore pipework performance. This ensures clean, obstruction-free lines and maximises cooling system output for commercial, industrial and residential buildings.
