Real Energy has developed an energy efficient evaporator coil called the Reihl Coil that can save over 50% of the energy used by conventional evaporator coils for walk-in coolers and freezers. The Reihl Coil uses phase change material to more rapidly absorb heat, reduces compressor run time, and provides passive cooling when the compressor is off. It is patented, approved for safety, and guaranteed to save businesses at least 38% on their cooler electricity costs with most systems paying for themselves within 2-4 years.

Overview
Real Energy is an American based company that has developed an energy efficient evaporator coil for use in walk-in
coolers and freezers. Our headquarters and manufacturing is located in the great state of Michigan. Evaporator coils
haven’t been improved in over 60 years. With the current energy crisis, and energy conservation on everyone’s
mind, we have developed The Reihl Coil®. It is the ONLY energy efficient evaporator coil on the market, and saves
over 50% of kWh used vs. a regular system. We see anywhere from 50-75% savings. This revolutionary design will
change the way all business cool their products. It will save money for the business owner and reduce the overall
energy used. The Reihl Coil has an 18 point patent and is ETL/UL and CSA Approved, and we offer a guarantee of
38% savings on all of our systems. In addition to the savings we also have seen a reduction in service calls.
Evaporator systems using The Reihl Coil® will reduce the energy consumption of a walk-in cooler by approximately
59%. The Reihl Coil® can be installed with a new cabinet or may be retrofit to an existing refrigeration system. ROI
for customers is 18 months-3 years depending on climate zone.

3. We Stand Behind Our Product
For businesses with six or more locations, we offer a free system for one location. (up to 3 units, typically 2
coolers and a freezer).
How it works: You choose a location, and we do an energy audit (we place monitors directly on the electrical
panel that controls the coolers), this will provide us with a baseline. This baseline will provide the exact KWH
each cooler is using. Real Energy will use one of our certified installers to install the system. We can also certify
your own HVAC/R company, or your preferred installer. (Our system is installed differently than non-energy
efficient models, so certification is required for proper installation and maintenance). After the coils are installed,
we will run the energy audit again to show the cost savings.
This revolutionary energy saving system will decrease your operations budget. Most systems have a 2-4 year
ROI, and save thousands each year, and every year thereafter!

Explanation of Design
The Reihl Coil® uses a PCM (Phase Change Material) which
allows heat to be absorbed more rapidly than a conventional
evaporator coil. The PCM absorbs heat that would cause the
refrigerant to vaporize in a standard system. The Reihl Coil® also
changed the conventional fin design by increasing the surface
area to improve the heat transfer process.
Thermodynamics
The addition of the PCM within The Reihl Coil® accomplishes two
important things:
A. Reduction in the compressors total run time.
B. Radiant cooling that maintains the cabinet and product
temperature while the evaporator fans are off.
By using the PCM, The Reihl Coil® is able to lower the suction
pressure. A lower suction pressure decreases the load on the
compressor which reduces its electrical consumption.
Suction Pressure

5. 5
With The Reihl Coil® design, air travels at a higher velocity
through the coil, aiding in keeping the coil clear. This cannot be
done with a conventional evaporator for many reasons:
A. A conventional evaporator is only cooling when the compressor
is running, whereas The Reihl Coil® has reserved cooling
during the compressors off cycle.
B. The evaporator design used by the competition is smaller. Less
heat can be absorbed in the competitor’s design due to the
reduced surface area in the evaporator fins.
C. All evaporator fan motors generate heat. The efficiency of The
Reihl Coil® requires fewer ECM motors compared with the
competition. Fewer ECM motors means decreased heat
generated during the compressor run cycle.
Coil Design
The Reihl Coil’s® patented coil assembly has demonstrated
energy savings of approximately 59% over the competitor’s system
of equal volume and controls.

Active cooling occurs during compressor run
cycle. Passive cooling occurs during rest
cycle via radiant PCM.
Humidity occurs due to a longer cooling cycle. Reduces humidity by drawing heat out of the
air more quickly.

Additional Information
 Many systems on the market have “energy saving” add-on components, such as ECM Motor fans and controls; our
system comes standard with these components. We do not believe in hidden add-on cost. Our system is as close
to “plug and play” as you can get.
 There are many other “energy efficient” add-ons that have come about over the past 5 years, different refrigerants,
energy control module, magic cubes, etc. However, these do not come close to the energy savings of our coil. We
use the ECM fans and the control in conjunction with the coil. The real savings is in the coil technology.
 The Reihl Coil® technology provides a new, more efficient way to remove heat from a temperature controlled
storage unit. It also reduces the humidity out of the cabinet.
 ETL certified to comply with UL, NSF, and CSA
 Patented (#8250881) Technology
