There are six fresh water cooled chillers producing over 3400TR cooling power in a commercial building. The condenser tubes are now kept clean and the performance of chillers is improved by 11.0% and the payback period is 24 months.

There are two fresh water cooled chillers generating 400TR cooling capacity to part of a commercial building. The condenser tubes are now free of mineral scale and biofilm. The resulting energy efficiency of chillers is improved by 16.0%. The investment is paid back in 20 months.

There are three fresh water cooled chillers (900TR in total) and two heat pumps (200TR in total) providing chilled water and hot water to a high technology building. The energy efficiency of chillers and heat pumps is improved by 9.6%. Moreover the ozonation system is replaced by AquaKLEAR. The payback period is 20 months.

There are four fresh water cooled chillers producing 1200TR cooling capacity to a high technology building. The condenser tubes are cleaned in one month and the resulting energy efficiency of chillers is improved by 9.7%.

There are three fresh water cooled chillers (two with heat recovery) producing over 1000TR cooling capacity to a club house. The condenser tubes are now free of mineral scale and biofilm. The resulting energy efficiency of chillers is improved by 8.9%. The investment is paid back in 13 months.

There are four fresh water cooled chillers generating over 1600TR cooling capacity to an office area and shopping centre of a commercial building. The condenser tubes are now free of mineral scale and biofilm. The resulting energy efficiency of chillers is improved by 12.6%. The investment is paid back in 13 months.

There are four fresh water cooled chillers generating over 2700TR cooling capacity to an office area and shopping centre of a commercial building. The condenser tubes are now free of mineral scale and biofilm. The resulting energy efficiency of chillers is improved by 8.0%. The investment is paid back in 27 months.

There are two fresh water cooled chillers generating 220TR cooling capacity to an office area and shopping centre of a commercial building. The condenser tubes are now free of mineral scale and biofilm. The resulting energy efficiency of chillers is improved by 8.9%. The investment is paid back in 38 months.

There are six fresh water cooled chillers generating 6000TR cooling power to a theme park. The water quality is now well controlled and the condenser tubes are free of biofilm which was the major source of heat impedence to the chillers in the past.

There are three fresh water cooled chillers capable to produce 1800TR cooling capacity to a hotel. The performance of chillers is kept as good as day one due to the cleaniness of the condenser tubes

There are five fresh water cooled chillers capable to produce 3000TR cooling capacity to a hotel. The performance of chillers is kept as good as day one due to the cleaniness of the condenser tubes
