Accucold brings advanced convenience to on-the-go vaccine refrigeration with the SPFZ25M, a fully featured portable freezer ideal for transporting sensitive materials while maintaining the integrity of the cold chain. This lightweight compressor-operated unit can be plugged into the 12V DC auxiliary power outlet/lighter socket inside any vehicle, as well as 24V sources. We also provide an AC adapter to allow the SPFZ25M to be plugged into a 110V electrical wall outlet. Sturdy side handles allow easy lifting and a factory-installed lock ensures you can secure the interior as needed. We include a collapsible trolley for easy mobility from vehicle to facility. The SPFZ25M is a freezer that can operate between -20 and -27 C, ideal for many vaccines and other medications. 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 SPFZ25M is ideal for applications that require easy transportation of cold items, such as collecting samples or administering vaccines at temporary locations. We also offer this model with a wide temperature range to run at standard refrigerator temperatures (see model SPRF26M). NOTE: Accucold freezers are purpose-built to the support meeting the current CDC (Centers for Disease Control) guidelines for the storage of vaccines. As referenced in the current Vaccine Storage and Handling Toolkit, these units incorporate several key features for stable operation. For additional temperature assurance, the CDC recommends a calibrated digital data logger (DDL). Select Accucold products have been tested and certified to the new NSF 456 standard, and are now available for purchase. For additional information, contact our products specialists.
