A major IT office complex in Chennai has a cooling tower of 100 m3/h to cool their office space. Although cooling infrastructure was enough, the cooling was inadequate. A.T.E. helped them not only improve the cooling, but also make a huge savings in power consumption and also fresh water consumption! Click here to find out how.

Challenge
A major IT office complex in Chennai has a cooling tower of 100 m3
/h capacity which they use to cool their office space.
Although this should provide more than enough capacity, the cooling was inadequate. Additionally, despite a chemical treatment
system in place, the cost of makeup water in the cooling tower was quite high.
Diagnosis
▪ Manual maintenance
processes led to lags between
measurement and dosing
▪ Wastage of treated water due
to manual blowdown
▪ Higher energy consumption
due to higher condenser
approach temperature
Solution
▪ Automated the dosing and
blowdown processes by
installing a Walchem
controller in the cooling
tower.
Results
▪ Automated the measurement of key parameters
of the dosing and blowdown process with
Walchem W600 controller
▪ The cycle of concentration was maintained at 6
(optimum level)
▪ Reduction in blowdown by 39.7%
▪ Savings of Rs 1,05,120 annually on fresh water
consumption .
▪ Decrease in the condenser approach
temperature from an average of 5ºC to 2°C
resulting in effective cooling
▪ Decrease in power consumption of the chiller by
6.32% saving Rs 1,966,072 annually
▪ 20% decrease in chemical consumption
The organisation was able to optimise its operations with the Walchem controllers (online monitoring
and automatic dosing) without any additional investment or increase in the current cooling capacity!
