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
