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. Nova Kool offers 26 DC and another 24 AC/DC models. Made to build into RV or marine cabinets, the R4500 cutout is 28.375 high x 20.25 wide and 21 inch exterior depth. Galvanized metal exterior with white ABS door. You can slide paneling or Formica, or even use a square of carpet on the door for durability and insulation. Well finished interior with 2 shelves, and vegetable crisper. Internal freezer 11″ x 12″ x 5″ high keeps ice cream and makes 2 full size ice cube trays included.  One year warranty, two years on parts.

Running power has been reduced with new dual voltage Secop (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. Two door models will consume up to 60 watts. 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 Secop (Danfoss) BD35F compressor uses R134A (CF3-CH2F) gas for atmospheric protection. This a very reliable refrigerator.
