Controlled Atmosphere storage requires more than just low temperatures.
It demands a sealed environment where oxygen levels, humidity, and gas concentrations are carefully regulated to preserve the freshness of perishable goods.
PSI CA Doors are engineered specifically for these environments—where small refrigeration cells must be accessed frequently without compromising the sealed integrity of the room.
