How cold can a freezer truck get?
In general they can maintain temperatures within the range of -65˚C to 40˚C, depending on the model and manufacturer. Common models can attain a smaller range (-25˚C to + 25˚C). This makes them suitable for a wide range of temperature sensitive cargo, from fresh produce to hazardous chemicals and more.
