3. PolarCool Performance
The following table shows estimates of the performance of three sizes of the PolarCool Evaporative Cooling
System. These values will vary depending on the particular installation and operating conditions. Both Variable
Speed(VS) and Single Speed(SS) models are listed.

36” SS Direct 10 gallons per hr. 7.0 amps @ 115v /60hz 10,000
48” SS Belt 17 gallons per hr. 11 amps @ 230v /60hz 17,500
48” SS Belt 17 gallons per hr. 8 amps @ 230v /50hz 17,500
Note 1: This estimate is under 90+ degree conditions; cooler temperatures will result in less
water usage.
Note 2: The cooling area is very dependent on the relative humidity, temperature, and the space
being cooled.
3.1 Temperature Differential Readings
The temperature drop from inlet to exit is very dependent on relative humidity and temperature. The higher the
ambient temperature and the drier the air, the greater the drop. A temperature drop of 10 to 20 degrees is common.
