Minimal Maintenance. No Moving Parts!
The Evaporcool System
uses multiple proprietary
technologies.
A Simple Principle
Hot outside air is cooled as it passes
through the EZ-Frame, before it reaches
the condenser coils.
This allows the system to operate as
though it were cooler outside than it
actually is.
On recent 100 degree days (73 wet
bulb), in a humid Southeastern U.S.
climate, the leaving air temperature of
the EvaporCool system entering the
condenser is 79.2 degrees!
EZ-Frame
The EZ-Frame™ framing system (patentpending) provides a unique mechanism
for protecting condensing coils, and
creates an environment in which air
temperature is lowered as it enters the air
conditioning unit.
The system is designed so that absolutely
no water transfers to the condenser coils.
Panels are attached by rare earth super
magnets for ease of unit access.
Removable Panel Screen
The easy to remove screens offer easy
access for cleaning and replacing media.
Magnets
SmartSpray
TM
The SmartSprayTM control box is the brain
of the EvaporcoolTM System. It monitors
the external environment and the HVAC
equipment in order to determine the
optimal amount of water to evaporate
into the air.
It also eliminates the need for a
recirculation system for excess water.

TESTING PROCEDURES
Step 1: Baseline Testing
Prior to installation of the Evaporcool System, a data logger* is installed on the subject HVAC
equipment to collect all applicable real-time energy consumption and unit performance information.
The duration of this test depends upon the weather at the location, but will typically last at least 2-3
weeks.
Step 2: Installation of the Evaporcool System
Step 3: Comparison Testing
After application of the Evaporcool System, real-time energy consumption and unit performance data
is collected. The duration of this test typically mirrors the duration of the baseline testing, but is also
highly dependent on the weather.
Step 4: Data Analysis
Once complete, all data is collected and analyzed by our in-house engineering department. We sort
all data by Cooling Degree Day, as provided by the National Oceanic and Atmospheric Administration.
The average kWh consumed during the baseline testing period is then compared that consumed
after installation of the Evaporcool System.
*All data was collected using either an Amprobe Data Logger (Model DM-II Pro) or a Satec Event & Data Logger (Model #EDL172XR or EDL174).

Water Conservation
•
The National Renewable Energy Lab (NREL) reports: “U.S. electricity production
consumes over 20 gallons of water per KWH created.
•
Other studies confirm this water usage and state that depending upon the power
plant type, the water usage can range from 10 gallons to 25 gallons of water
consumed per KWH created.
•
The EvaporCool system uses approximately 1.9 gallons of water for each KWH
saved. This saves approximately 90% of water usage while saving electricity
•
Based on national averages, on a 75 ton hvac unit, the EvaporCool system will use
$78 of water in a year, while saving over $7,000 annually in electricity.
•
By reducing electricity demand and consumption, Evaporative Cooling actually
SAVES water on a global scale!”
Kinetico Water Treatment
Kinetico salt/resin ion exhange water treatment
used on many “hard” water sites. Removes the
minerals (calcium and magnesium primarily)
from the water stream. Requires occasional
addition of salt to the tank.
HydroFlow Water Treatment
Uses advanced water treatment technology, the Evaporcool System
operates best in soft water hardness environments.
How Hydropath Technology Works
The difference between Hydropath Technology and other physical water
conditioning technologies is the induced signal and its ability to treat an
entire system continuously. HyrdroFLOW’s water conditioners induce an
electric signal of ±150 kHz into any water pipe on which they are installed
(copper or PVC). The electrical induction is performed by a special transducer
connected to a ring of ferrites. Just as an electrical wire carries a current from
point A to point B, the water inside the pipe acts as a conductor and carries
the induced electric signal throughout the entire water system. The oscillating
sine waves of the induced AC signal cause the positively and negativelycharged ions to form suspended clusters in the water, preventing them from
attaching to surfaces. These clusters “clump” together into a fine, white
powder that collects on the Evaporcool media in small quantities (measured
in parts per million) that occasionally need hosing off the media when any
dust in the air is hosed off. Testing shows that compared to other non
chemical electronic water treatment technologies, Hydropath Technology is
30,000 times more powerful.
HydroFlow Water Treatment
HydroFlowTM System:
• No Salts. No Chemicals. No Magnetic Coils.
• Unit transmits a unique radio frequency
signal that effectively breaks up existing
limescale and prevents future buildup
protecting the entire plumbing system.
• The HydroFlow unit simply clips to the pipe,
is plugged into an outlet and is switched on.
There is no plumbing or electric work
required.
Optional Booster Pump
Booster pump needed if
water pressure at HVAC
unit is less than 60 PSI.
Evaporcool is one of the few products that reduces the energy usage of air cooled HVAC equipment.
Using evaporative cooling to precool the entering condenser air has been around for decades. There
are reasons that Evaporcool is the market leader in this market.
Some system details of the Evaporcool system include:
1. Dramatically reduces the entering condenser air temperature. These systems have had a U.L. testing analysis and
thousands of systems operating successfully. On a humid, 95db/78wb outside design day, the Evaporcool unit will
cool this air to approximately 82 degrees db. Depending upon unit type, this reduces the energy usage by 20-22%
or more.
2. KW demand is reduced
3. Due to the Evaporcool filter media, dirt in the air is prevented from reaching the condenser coil. This saves on
annual condenser coil cleaning labor. It also increases efficiency.
4. Since the units run at a lower condensing temperature, repairs are minimized. The reason air cooled units
typically require considerably more repairs in the heat of the summer is because of the high condensing
temperatures and pressures that normally are experienced.
5. With the reduced condensing temperatures and pressures of the Evaporcool system, equipment life can be
extended.
6. Typical payback periods, only counting the energy savings, are approximately 2 to 4 years. Rebates and
incentives are available in many locations.
7. This is one of the few technologies that increases energy efficiency but at the same time does not negatively
affect the room temperature.
8. Cooling capacity increased approx. 8-12 percent.
The design advantages of the Evaporcool system include:
1. Evaporcool does not spray water onto the condenser coils. It sprays water within the Evaporcool
casing causing the Evaporcool filter media to remain saturated. This cools the air and prevents
moisture from collecting on the condenser coil. In addition, even though no water is sprayed on the
condenser coil, the water is filtered and treated with a water softening system.
2. The condenser coils are filtered from dirt in the air that has to be cleaned regularly and causes
energy inefficiency.
3. The air pressure drop through the media pad is very low (less than 1/10 of an inch) by design
4. Units are attached to the A/C units with rare earth super magnets and quick attach couplings. This
allows the Evaporcool units to be quickly removed if necessary for repairs and maintenance. System is
totally non-invasive.
5. The SmartSpray computerized controller sprays the precise amount of water to minimize water
usage and prevent water draining on the roof. No recirculation system or drain system is required
6. Some of the Evaporcool clients include AT&T (many sites), Verizon, Hewlett Packard,
the University of Tennessee and many other high profile clients.
