I want your recommendation on reducing a water bill at a factory I service.
They currently have 45-50 water cooled units totaling approximately 1700 tonnes of cooling. In the summer the equipment runs almost 24/7 I have done done some preliminary figures and estimate they use 5000 GPM!!!!!!!!!
Most units are Comfort-Aire M# WPC-120-5 and WPC-60-5 (10 tonne 575 V) and (5 tonne 575 V)
Switching the units to air cooled is NOT an option. Temperatures in the plant range from 70F in the winter to 120F in the summer.
I maintain and check the water regulating valves each spring and like to set them for 100F condensing.
I am not against pricing out a closed loop system but I don't have alot of experience in that area. I dont think a cooling tower alone would work because I would like to aim for 60-65F inlet and will have 90-110F outlet.
Any information or help would be appreciated.
I work in south eastern Ontario to give you an idea of weather conditions.
