Make one of your largest electrical loads one of your smallest!
(Recommended for drier climates. Works when humidity < 40%)

  • Cut your cooling costs by up to 90%
  • Low wattage cooling: from 20 to 150 watts
  • This is a cooler that runs on 1 or 2 solar panels, or a car battery charger!
  • The perfect cooling solution for buildings powered by solar, wind or hydro power
  • Short payback period
  • More environmentally friendly - no freon
  • Cabinet is 24 gauge stainless steel, warranted against leaking for 5 years.

How it Works:

Solar Chill - Evaporative CoolersCool 110°F air to 75°F by evaporating water. Nearly 16,000 BTUs of cooling is gained for each gallon of water evaporated. Evaporation rates in the Solar Chill™ can range from 1 to 7 gallons per hour. The extremely low wattage allows the solar chill to operate well on just one or two solar PV panels. This lowers the payback period for a Solar Chill™ system to about 3 to 5 years. Though we recommend powering the Solar Chill™ with PV's, they can also be run on 115 VAC Adapters, or even a car battery charger!

The Solar Chill™ uses an 8" thick, wetted CelDek™ pad, and is efficient for both airflow and evaporation. The Celdek costs $20 per cubic foot. The large cooler pad costs $75 (included with purchase) and should last for 5 years with proper maintenance.

Highly efficient DC motors, usually with permanent magnets replace the inefficient AC induction motor. Propeller fans are used to move the air in the Solar Chill™ instead of the traditional squirrel cage type blower (which require higher wattage's).

Minimal duct work is recommended with a Solar Chill™ to obtain maximum efficiency with lower wattage's. All of our models can optionally be made into down draft models for roof installation, with the addition of a 90 degree elbow. Local sheet metal shops can easily and inexpensively make one of these out of 24 or 26 gauge galvanized steel.

Why Solar Cooling?

Solar power and cooling go together like bread and butter. They are a perfect match. The more intense the sun shines, the more cooling energy is available. And if you have "time of day metering" higher electrical rates during the daytime (peak), and lower rates at night, you will have even more opportunities to save on your utility bills.
