Walk-In Solar Power Refrigerators
Large scale refrigerators or freezers built
to your specifications. Brushless DC
motors, eutectic plates, super high
quality and efficiency. This
pictured system transports tree
seedlings and fits on a standard
pick-up truck.Can operate from
vehicle or aircraft power, utility
grid or generator power, or
from photovoltaic and
other
alternative
power
sources. It
cools 230 cubic
feet with 470
peak watt PV array. Internal
temperatures stay between 45° to 55° F—a larger PV array
required for lower temperatures. Other applications include fish or food
storage, eco-tourism, campsites catering to adventure travelers, rural schools,
exotic flowers preservation during delivery to an airport, disaster relief and
storage of medical and veterinary supplies.

Coldsaver
15.1 cu.ft. Eutetic
Freezers
Specifically designed to
run from a generator or
where power
unavailable or
unreliable, “Eutectic”
glycol tanks store the
cold for use when no power is
available. You only need 1.5 hours of power
each day if room temperature 70 degrees, 3 hours if 80 degrees. Use a
generator (small, 2.2 kW enough), grid, wind, or solar power. Thick and
dense polyurethane insulation (80–120 mm) keeps the cold in, heat out, and
your food frozen for 24–36 before you need power again. And it gets cold
(down to -40 degrees F). Uses CFC-free ester oil R404A refrigerant and a
Danfoss BD 35f compressor. 10 interior baskets; 15.1 cu.ft based on actual
size, 18 cu.ft based on the common practice of adding 20%. 63" x 29" x 35",
396 lbs. 360 watts.

Appropriate Technology in Action
Mohammed Bah Abba, Nigeria
Mohammed Bah Abba discovered a way to use
inexpensive, locally available materials and
make simple refrigeration systems. Easy to
make, inexpensive, and requiring no
electricity, they still work incredibly well -
eggplants stay fresh for 27 days instead
of the normal 3, peppers and tomatoes
last 21 days or more; and African
spinach that normally spoils in just 1
day, lasts for 12. By putting a smaller clay
pot inside a larger one with wet sand in
between, he found that the natural
evaporation creates a refrigeration process
with a cost of only 30 cents! We’re
experimenting to help improve this process and
testing a solar powered fan blowing across the top of the pots as well as
using a third outside pot filled with water.
