Solar Evaporative Coolers
The rust-proof housings are built of 304 stainless steel, and use a 6" thick fluted pad as the wet
cooling media. This pad is the most efficient evaporative cooling media in the world, and it will
last five years with minimal maintenance. The solar evaporative coolers use only 25 to 130
watts! Only 80 Watts for 4500 cubic feet per minute (CFM). Use the 24" or 2-20" if the cooler
will be connected to ductwork. Optional rheostats may be used to slow fan speed. Optional
Control Packages with clean out pumps are available.

For array direct operation of evaporative coolers use an array with atleast the recommended
watts and choose a Linear Current Booster on page 125 with the correct amp and voltage rating.
