When you are looking for energy efficient refrigeration, Cool Blue has just what you want. A six cubic foot box requires only half as much power as other 12-volt systems and can run off of one 75-watt solar panel. In addition to being efficient, the system runs on an environmentally friendly refrigerant, and the holding plates use a non-toxic freezing solution. The system can also run on CFC-R12, the only refrigerant available in many parts of the world. The unit averages 21 amp hours per day for a well insulated freezer/refrigerator and can be owner-installed with no special training. For more information, go to www.technauticsinc.com.
