Solar Cold
The new developed
20-ft-cold-storage container ist designed for cold-storage of varying food-stuffs with regard to extreme ambient conditions, e.g. for hot and rich of sunshine areas with different conditions of relative humidity,
and with an assured inside temperature level over approx. five consecutive days under very low solar radiation rates only.
Main features
