What is the value of a certified tower?
15% undersized CT 0.5C warmer return water
0.5C higher return water ~ 2% chiller inefficiency
Assume:
1500 Ton cooling tower application
1000 kW chiller installed motor power
$0.10 / kwhr
Chiller operating 75% of the year
Yearly chiller energy savings by selecting a CTI Certified tower
13,140 USD
A properly sized cooling tower makes the chiller more efficient

Recommendations
1. Specify CTI or Eurovent certified cooling towers
2. Clearly specify flow rate, hot water, cold water, andwet bulb temperatures
3. Do not increase the flow rate or wet bulb temp tomake up for underperforming cooling towers notneeded for certified towers
A certified tower assures the highest possible energy efficiency
