WSA Brush-type Automatic Tube Cleaning Systems (ATCS) were installed on the centrifugal and absorption chillers. The two systems are returning the total cost of their original installation every year in energy and labor savings. These savings are a direct result of reduced energy consumption and maintenance. Prior to installation of the WSA Brush-type Automatic Tube Cleaning Systems the fouling factor was .0018 and two to three manual tube cleanings were required every year. Since installation, fouling factors are less than .0002 and manual cleaning has not been required.
