Nova Kool R4500 4.3 CU FT Single Door Refrigerator with Freezer Compartment AC/DC or DC only.

Model 4500 – R4502 Single door Refrigerator with Freezer Compartment – 4.3 Cut Ft AC/DC or DC only.

The Nova kool units are a best buy in a small refrigerator for off grid power.  They’ve been favored in our catalog for over 20 years.  One year warranty, two years on parts.

Running power has been reduced with new dual voltage Danfoss compressors and a new refrigerant. Single door models consume about 35 watts when compressor is running: under 3 amps 12 volt, 1.5 on 24 volt. Running time varies with temperature, but is about 30% duty cycle on a 70 degree day. Buyer glues extra 2″ foam insulation to the whole box to cut per day run time and power used in half. As supplied the R4500 uses 480 watt hours / day, but with added insulation, just 240 watt hours a day on a 70 degree day. The new Danfoss BD35F compressor uses R134A (CF3-CH2F) gas for atmospheric protection. Interchangeable for use on 12 or 24 volt.  Reliable refrigerator.
