What makes the FridgeFreeze vaccine refrigerator/freezer so efficient?
The FridgeFreeze vaccine refrigerator/ freezer is so efficient because its casing is made of marine-grade aluminum and the unit employs the entire outside casing as the condenser to dissipate heat. By contrast, other portable fridge/freezers use a fan and an external condenser. Fans are much less efficient because they increase the amp draw, and external condensers are more likely to corrode or break.
