AdobeAir, Inc. certifies that the evaporative air cooling
products shown in this catalog are licensed to bear the
AMCA Seal. The ratings shown are based on tests and
procedures performed in accordance with AMCA
Publication 211 and comply with the requirements of the
AMCA Certified Ratings Program.

Features
Energy Efficient
Fan Design
Arctic Circle High Capacity
Evaporative Coolers use energy
efficient fan blades to move the air.
Our fan coolers move more air
while using less horsepower than
comparably sized blower wheel
(squirrel cage) models. And since
simply any fan blade won’t do,
Arctic Circle adjusts the pitch of
the blades for each specific model
to assure maximum air delivery!
Designed For Low Static
Pressure Applications
Arctic Circle High Capacity Evaporative Coolers were
developed for applications where air from the cooler is
being discharged directly into a space making them ideal
for factories, warehouses, agricultural buildings and other
installations with straight discharge plenums without
ancillary duct work. For ducted applications with
external static pressure exceeding 0.2” water
gauge, Arctic Circle recommends their line of
blower wheel models.
U.L. Listed
Arctic Circle High Capacity Evaporative
Coolers are U.L. listed for non-ducted
installations, meaning you can rest
assured that they meet or exceed most
local and national codes.
Design and Construction Features:
■Heavy duty galvanized steel construction using industry proven best methods and practices.
■Industrial grade, electrostatically applied powder coated finish for maximum durability.
■High grade aspen pads ensure maximum cooling efficiency.
■Center fed PVC water distributor system maintains crucial pad wet-out.
■Specially designed fan blades provide maximum air delivery at minimum cost.
■Separate GFCI receptacle offers a convenient and safe method of supplying power to the pump.

Arctic Circle can deliver around 17,000 cfm at 0.0” water
gauge using a 1 1/2HP motor. A comparable blower
wheel model requires up to 5 HP to deliver the same
volume of air. That’s at least 65% lower cost!

Double Sided
Louvered Pad Frame Design
Arctic Circle has over 50 years of experience in designing
evaporative coolers for commercial, industrial and agricultural
applications. We’ve designed this special pad frame to assure
that water stays where it is supposed to be — in the pad! Both
the external and internal louvers constantly direct water into the
pad, and away from the air stream.

All external wiring and components such as disconnects, motor starters, and over-current
protection are to be field supplied and are not included as part of the evaporative cooler from the
factory.
A separate 120 volt, 60 hertz, 1-phase pump electrical circuit is required to maintain the
integrity of the GFCI pump protection and to maintain the U.L. listing of the evaporative cooler.

The most accurate sizing is accomplished by the use of KoolKalk, our software
program, when you have already calculated the sensible cooling load of the
building. KoolKalk combines ASHRAE design day conditions, the principles of
psychrometrics, and hourly weather data of typical meteorological years for key
cities around the world. Contact your AdobeAir sales representative for a free
copy of KoolKalk, or see our website at www.AdobeAir.com.
Although not the preferred method, alternate sizing by considering only air
changes in the building may be adequate for some warehouse and other
industrial applications. To select a cooler or coolers based on air changes only,
follow these simple steps:
1) Determine the size (in cubic feet) of the space to be cooled (length x width
x height). Remember that in most cases a height of from 10-12 feet is all
that needs to be considered since that is typically only the height to which
cooling is required.
2) Determine how frequently the air needs to be changed in the building (minutes per air change) by referring to the chart and
map above. As an example, a warehouse in El Paso, Texas (zone 2) with an average interior heat load and exposed exterior
heat load needs an air change at least every 3 minutes as a rule of thumb.
3) Determine the total CFM required for the building by dividing the cubic feet of the space to be cooled by the number of
minutes for each air change.
Example:
Building size = 200’ long x 100’ wide x 12’ height to be cooled = 240,000 cubic feet to be cooled.
Air needs to be changed every 3 minutes (El Paso, Texas example from #2 above)
240,000 / 3 = 80,000 cfm total delivered air required from coolers.
Select coolers delivering a combined total of 80,000 cfm.
