Drzwi gazoszczelne

 Doors are applied for rooms with controlled atmosphere (CA).
CA is regarded as the best technology to store fruits and vegetables.

In standard coldrooms fruits are stored in normal atmosphere containing 21% of oxygen and 0% of carbon dioxide. Whereas in the controlled atmosphere the contents of oxygen is below 3% and the content of carbon dioxide is below 5%. This leads to prolongation of fruits and vegetables store period without losing their commercial quality.
