Pad Size Requirements
To determine the size of the ExpressCool™
panelized system or the spray-on fogging pad
needed for your building:
1. Determine airflow in CFM (cubic feet
per minute). Add up the capacity of
all the fans in the building.
2. Decide on your desired pad height.
Pads are available in heights of 2 to 6
feet. Allow an additional 16 inches for
CT Cooling Systems, and 13 inches for
CB Cooling Systems.
3. Determine the length of pad required
for your CFM. Divide your CFM
requirement by the following number
for your selected pad height:
6-inch pad x 12-inch wide
• 700-750 for 2 foot high pads
• 1,050-1,125 for 3 foot high pads
• 1,400-1,500 for 4 foot high pads
• 1,750-1,875 for 5 foot high pads
• 2,100-2,250 for 6 foot high pads
Fogger pads x 24-inch wide
• 2,400-2,600 for 4 foot pads
• 3,000-3,250 for 5 foot high pads
• 3,600-3,900 for 6 foot high pads
