SINGLE-STAGE INDUSTRIAL EVAPORATIVE COOLING
Direct Evaporative Cooling
Put simply, whenever water is evaporated, heat
is absorbed. This basic principle underlies the design
of the MasterCool direct evaporative cooler.
High Quality Construction
Hot-dipped galvanized steel, welded for maximum
strength is combined with our exclusive POLYBOND®
fi nish that protects the whole system – cabinet
pans, distributor covers, louvers, and all other parts
contacting water. The electrostatically applied
polyester epoxy powder-based coating is cured at high
temperature and is so durable that these models are
backed by the best warranty in the industry.
Energy Efficient...
Environmentally Friendly
With no compressors or condensors, MasterCool
evaporative coolers offer signifi cant energy savings
over mechanical refrigeration units; and, with no
CFC’s, do not contribute to depletion of the ozone
layer. Their air washing effect improves indoor air
quality with fresh, fi ltered air constantly brought into
the cooled space...forcing stale air out.
Direct Evaporative Cooling Process
Direct evaporative cooling exchanges sensible heat for latent heat,
and follows upward along a constant wet-bulb temperature line on the
Psychrometric
Chart. The result
is a dry-bulb
temperature of
the leaving air
(B) approaching
the wet-bulb
temperature of the
entering air (A).
Standard and Hi-Performance Models
The fl exibility of modular components allows selection of CFM and
saturation effi ciencies producing the sensible heat capacities needed to
meet design requirements. For
many applications, our standard
8” media continues to be an
economical choice, with an 80%
saturation effi ciency at 450 FPM.
For more demanding design
conditions, our 12” media offers
90% effi ciency at around 450
FPM.
MasterCool Evaporative Media
MasterCool evaporative media is constructed
of special cellulose material, impregnated with
insoluble anti-rot salts and rigidifying saturants.
The cross-fl uted design continually directs
water to the air-entering side, inducing a highly
turbulent mixing of air and water for optimum
heat and moisture transfer.
Comfort Levels
Not only does evaporative cooling lower the temperature
in the space to be cooled, it also lowers the temperature
you feel. Rapid air movement produced by the
MasterCool increases skin evaporation which causes you
to feel 3-5° effectively cooler than the temperature read
from a thermometer. Evaporative cooling can provide
effective temperatures acceptable in most commercial/
industrial applications throughout the world.
Typical Applications
The Industrial MasterCool is used for area cooling or
spot cooling. In many areas it can replace or supplement
mechanical refrigeration needs in agricultural,
institutional, commercial, and industrial applications.
Applications such as kitchens, laundries, gymnasiums,
heat treating areas, and dry cleaning plants requiring
large quantities of fresh air moving through the building
are ideal candidates for evaporative cooling.
