Why Evaporative Cooling?
Evaporative cooling is cool the way nature intended, like the cooling sensation
you feel when you get out of a swimming pool. Water evaporates from your skin,
taking heat with it. The Mobile MasterCool units draw hot air through wet pads,
using a blower or fan. As the water evaporates, it takes heat with it, resulting in
the discharge of air that is up to 30 degrees cooler.
Isn’t Evaporative Cooling just for dry desert climates?
While evaporative cooling is especially suited to dry desert climates, it is also
effective in more humid areas. As temperatures rise throughout the day,
relative humidity levels drop. Usually by midday, humidity levels have dropped
to well within the range where the Mobile MasterCool units can provide relief
from the heat.
1. What is Mobile MasterCool ?
Mobile MasterCool is a line of completely portable evaporative coolers that require no installation or wiring. This high-velocity, high-efficiency line of
coolers provides spot cooling for areas ranging from 700 sq. ft. to 3,000 sq. ft. and can be used in settings from residential to commercial and industrial.
2. How will Mobile MasterCool save me money?
First, Mobile MasterCool saves you money by putting cool air exactly where you need it. Spot cooling saves you money because you're not cooling your
entire facility. Second, keeping employees cool helps reduce the risk of heat exhaustion or fatigue and the potential for lost work time, workers'
compensation costs for heat-related illness and can help increase productivity.
3. Where should a mobile cooler be placed within a space?
The cooler should be placed where there is plenty of fresh air and it is best positioned adjacent to an external door (or open window) with additional
openings on the opposite side of the room for relief air. Placing the cooler this way allows the cooler to draw fresh air from the outside to be drawn through
the pad, cooled, filtered and circulated through the room while the hot, stale air is forced out through the openings on the other side of the room.
4. How much maintenance does a mobile cooler require?
Minimal. We recommend emptying the water reservoir once a week to reduce scale or mineral deposits on the pad. Periodically during extended periods
of use, or at least once per year depending on the usage, it is important to perform some simple cleaning to maintain its efficiency. This involves cleaning
the water system and filters. Refer to the Owner’s Manual for detailed instructions and a maintenance schedule for each particular model.
5. Are evaporative coolers more suitable to specific climates?
While evaporative cooling is especially well-suited to dry, desert climates, it is also effective in areas of higher humidity. Even in areas of high humidity,
there are many cost effective uses for evaporative cooling, making it the right choice for spot cooling inside or out.
6. How do evaporative coolers save energy?
On average, an evaporative cooler consumes about one-fourth of the electrical energy required to operate a refrigerated air conditioning unit. As an
example, to cool approximately 2,400 sq. ft.(the average size of a home in the U.S.), a refrigeration unit would require three electric motors with a
combined horsepower of 3 ½. To cool the same space, a MasterCool unit would only require a ¾ horsepower motor, drawing only 11.3 amps.

Constructed of powder coated metal with the strength of
encapsulated steel in a durable polyester epoxy finish
for maximum life, this line delivers cool, clean air using
premium MasterCool rigid cellulose media. Compact
and powerful, our energy efficiency is second-to-none.
The efficient electrical system with low amps and low
wattage draw helps you save money and can help
increase employee productivity. We call that EcoCool ...
economical and cool.
Evaporative cooling consumes only one-fourth of the electrical
energy required to operate a refrigerated air conditioning unit.
Using Mobile MasterCool costs pennies a day, can save you
potential lost labor and workers’ compensation claims due to
heat related illness and can help increase productivity.
With evaporative cooling, a complete air change occurs every
one-to-three minutes. This advantage over traditional air
conditioning or simply having employees work in stale,
stagnant air, keeps the air cooler and cleaner.
• Constant air movement pushes heat out, along with stale air,
smoke, odors and pollution.
• Evaporative cooling produces a high volume of fresh, cool
air, helping the body ventilate naturally … keeping employees
cooler and happier.
Mobile MasterCool evaporative coolers operate efficiently at maximum
capacity using 500-Watt to 1,500-Watt generators.
