You can measure that the oxygen decreases and the carbon dioxide rises in the cold chamber immediately after the chamber starts to be filled with pre-storage products, this is related to the fact that the fruit starts to breathe after harvest: Fruits take Oxygen -O2- after harvest and start to produce Carbon Dioxide -CO2. N2 Generators reduce the O2 level in the cold room immediately after loading and reaching the core target temperature in order to reduce the respiration rate and extend the storage time. On the other hand, CO2 scrubbers keep the CO2 level at the desired level throughout the storage by algorithmically balancing the rising CO2 level with instant measurements by the additional analyzer once the fruit loading operation in the warehouse is completed, while the O2 level in the cold room decreases, in order to further extend the storage period.

The CO2 scrubber  works by capturing and separating CO2 from a confined space or gas stream. Fruits and vegetables are living things that breathe, that is, they also produce CO2. Therefore, CO2 levels must be kept in balance during storage. CO2 scavengers ensure that the CO2 does not exceed a preset value and if not adjusted and stabilized this can cause serious losses.

The Carbon Dioxide scrubbers preferred and recommended by OXYCAT have a number of unique features. By using a flexible air buffer, where after regeneration the activated carbon tank is temporarily filled with low-oxygen cold storage air to make it oxygen low, it can almost completely prevent unwanted oxygen ingress into cold stores. In addition, with the scrubbers that offer absorption-retention and regeneration-cleaning options based on the unique CO2 measurement, the CO2 scrubber is always automatically optimized, so cycle times do not need to be constantly checked by the user or adjusted frequently. Thanks to such techniques, finishing touches and fine adjustments, OXYCAT scrubbers can gain up to 20% more capacity with the solutions we prefer.
