Controlled Atmosphere: The Key to Fresh Produce Preservation during Transport – ATEB’s Expertise in Refrigerated Transport

  • Controlled Atmosphere (CA) refers to control of the gaseous composition of the storage atmosphere.
  • By default, the atmosphere in the container will be equivalent to that of our atmosphere – 78 % Nitrogen, 21 % Oxygen, and 1 % Argon. But as the products transported under CA-conditions are fresh produce, they both consume O2 and produce Co2 on equal terms as humans. To maintain an ideal atmosphere in equilibrium with the products’ deterioration rates, the atmospheric composition is changed to ideal levels of O2, CO2, and other gases that match the specific cargo load.
  • Controlled atmosphere is a refrigeration technique in which the gas composition is modified in a refrigeration chamber or refrigerated container. In this way a regulation control of the physical variables of the environment (temperature, humidity and air circulation) is carried out.
  • The controlled atmosphere is applied to all types of transport of fruit and vegetable products and is generally characterized by having an atmosphere impoverished in oxygen (O2) and enriched in carbon dioxide (CO2). In this way, the composition of the air is precisely adjusted to the requirements of the packaged product and remains constant throughout the transport process.
  • As specialists in refrigerated transport, at ATEB we always take this into account in order to adapt to the needs of each load and customer. When transporting perishables, it is essential to consider these types of issues in order to ensure success once the journey has been completed.
