SunDanzer Chest Type Freezer or Refrigerator – SunDanzer has focused exclusively on the solar refrigeration business for many years and we love their products. The chest type 50 litre, 165 litre and 225 litre units are the best sellers, and the most efficient. We include free thermostats with the units so that you can switch them from freezer to refrigerator in the field. The units self-select between 12v and 24v and provide years of trouble-free service. We use a 165 litre fridge at our office in Arizona and run it easily with one 85w solar module.
SunDanzer Cabinet Type Refrigerator/Freezer Combo – This unit is more convenient than the chest type, but not as efficient (more cold air is lost when the door is opened). However, it does include a freezer compartment and uses the same compressor and thermostats as the chest type unit. This is a good choice for consumers who want the easy access of a cabinet type unit. Based on our tests in a 6 sun hour environment in Arizona, we recommend at least a 135w solar module, and probably a 175w module in most parts of Africa.
SunDanzer WHO Approved Solar Battery-Free Vaccine Refrigerator – If your customer requires a World Health Organization (WHO) approved vaccine refrigeration system, then you will want to use the SunDanzer BFRV 15liter or 55liter model. Remember that the entire system should be installed per WHO specifications in order to meet the standard – the refrigerator is just one component and will not work well in a poorly designed or poorly installed system. Because these are DC direct units, the manufacturer recommends a certain module orientation. The modules need to be arranged in an East / West array. Refer to the information below.
