The Star Cool CA is a controlled atmosphere application designed to prolong the shelf life of perisha-
bles by regulating the internal atmosphere of the container. The container's atmosphere obtains
the desired gas composition based on entered setpoints for O
desired atmospherical composition of the gas serves to lower the respiration of the perishables,
and thereby providing a prolonged shelf life.
