Temperature: Each type of product has an optimal storage temperature. Reefer containers can adjust temperatures between -30°C and +30°C, although there are more powerful units that can reach up to -65°C, suitable for deep-frozen products.
Humidity: Humidity levels are critical to maintaining ideal conditions during transport and are measured in relative terms (0-100%) .
Ventilation: Fresh produce, such as fruits and vegetables, release carbon dioxide and ethylene during storage. The accumulation of these gases can damage merchandise, so ventilation is essential for the transport of these products.
