The Cool Case consists of a Robust Case with insulation made of foam type LD29, reusable cooling elements and a plastic transport goods container (with 5.5 l or 19 l useful volume). The cooling elements have an insulating layer on one side, which prevents subcooling of the goods and ensures a constant temperature output. The cooling elements are food-compatible and can be reused indefinitely.
The specified cooling duration of 30 or 48 hrs. of the four standard sizes was determined by the bwh case experts for the bwh test environment with specified conditions. The temperature stability depends on many physical factors and must be tested individually for each transport item..
