Thanks to the controlled atmosphere, the Controlled Atmosphere Rooms take O2 and then give off CO2 in order to improve the respiration of vegetables and fruits. Vegetables and fruits are stored in a gas-tight environment. The oxygen level in the air is lowered. Then the CO2 is increased. Controlled Atmosphere Rooms allow long-term storage of vegetables and fruits to minimize their aging and maturation to preserve taste and quality. Thanks to the Controlled Atmosphere Rooms, the rapid maturation (aging) of fruits and vegetables is prevented. Respiration is prevented in vegetables and fruits as it adapts to the gas conditions in cold storage. In controlled atmosphere rooms, the products are protected without applying chemicals. In this way, the life of many products is increased by 2-4 times.
