Case History
- 70%
Improvement in
corrosion rate - 14%
Reduction in
water usage - 99%
Improvement in
chemical control
Before Application
- ・Water conductivity swing caused chemicals residual build up.
- ・Heat load swings in the cooling tower caused evaporation rate to increase.
- ・Manual control of chemical injection.
After Application
- ・Reduced the frequency of scheduled monitoring from daily to weekly.
- ・100% compliance of cycles.
- ・Chemical residual improved from 34% in-range to 99% in-range.
- ・Corrosion rate reduced from 3.6 mpy to 1.1 mpy.
