Hongkong Land: COP Up 10-15%, Biofilm Removed

Home 9 Case Studies and Results 9 Hongkong Land: COP Up 10-15%, Biofilm Removed
Key results
10-15% COP improvement
2 months to remove biofilm
5 buildings treated

Case Study from HYDROPATH Asia

The Challenges

  • Biofilm remaining on condenser tubes
  • Annual tube cleaning required
  • Electro-chlorination and ATCS still in use
  • Chlorine discharge limited to 0.2 ppm

The Solution

HydroFLOW® treatment was first installed at Exchange Square on the seawater cooled chiller plant, then rolled out to four more buildings. The signal disrupts the conditions that let biofilm establish on condenser tubes, clearing it within two months.

Key Outcomes

R

Condenser tubes free of biofilm in two months

R

Automatic Tube Cleaning System shut down

R

14-month log showed COP up 10-15%

R

Worked within the 0.2 ppm chlorine limit

Independent Verification

All results in this study were measured and verified by third-party facilities managers and technical staff.
