A plan to purchase items that do not contain or use chlorofluorocarbons and is therefore "ozone safe". As part of this plan, switched a chiller over to a non-ozone depleting refrigerant and 12,000 lb of CFCs (R-12) was retired.
Focuses on optimum utilization of equipment that uses chilled water, and controlling chill water supply and return temperatures.
Currently, Sonoxide (sound) is used to kill bacterial and other organic contaminants in the cooling tower water. This replaces the use of chlorine dioxide which required the use of chemicals such as hydrochloric acid & hypochlorite solutions.
