Accucold by Summit Appliance brings advanced convenience to on-the-go refrigeration with the SPRF26, a fully featured portable cooler that can be set at refrigerator or freezer temperatures. This lightweight compressor-operated unit can be plugged into the 12V DC lighter socket inside any vehicle, as well as 24V sources. We also provide an AC adapter to allow the SPRF26 to be plugged into a 110V electrical wall outlet. With a resilient gray plastic exterior and sturdy side handles, this unit is easy to carry for mobile applications, such as off-site vaccinations. An optional transport trolley is available for purchase. The SPRF26 can be used as a refrigerator or freezer that can reach -15 C temperature. A digital thermostat with an external LED thermometer display allows easy temperature control without requiring users to open the lid. The hammered aluminum interior can hold up to 26 liters. With a versatile design and superior construction, the SPRF26 is ideal for applications that require easy transportation of cold items, such as collecting samples or administering vaccines at an off-site location. NOTE: Accucold refrigerators are purpose-built to the support meeting the current CDC (Centers for Disease Control) guidelines for the storage of vaccines. At this time, Accucold refrigerators have not been evaluated to the new NSF 456 standard. For additional temperature assurance, the CDC recommends a calibrated digital data logger (DDL), which can be added with the purchase of a DLSA11CAL accessory.
