C0₂ Scrubbers

Carbon Dioxide adsorbers are used to remove Carbon Dioxide (CO₂) from a gas tight Controlled Atmosphere (CA) store for fruit and vegetables.

Just like us, fruit and vegetables respire using the oxygen (O₂) that is naturally present and as a result produce CO₂. When a CA store is sealed the respiration of the fruit will decrease the the O₂ and the CO₂ will increase. Ultra low oxygen (ULO) storage requires that the CA stores are extremely gas tight. As the name suggests ULO storage requires minimal oxygen levels present in the store and to be able to achieve this it is important to have the right equipment. When using a single bed absorber in combination with a lung minimal oxygen levels are easily achievable in a tight store.

Explanation of the lung procedure

1. Emptying of the lung. Before adsorption starts the oxygen level is reduced by moving low oxygen air from the lung to the carbon carbon.

2. Adsorption. By circulating the selected stores air through the carbon bed the carbon dioxide is adsorbed.

3. Filling the lung. The low oxygen air that is present at the end of the adsorption is transported to the lung.

4. Regeneration. The carbon dioxide is removed by circulating air through the varbon bed. This is the final part of the cycle and the adsorber is now full of fresh air that will be removed at the beginning of the next cycle by emptying the lung.

The fact that the atmosphere in the lung is isolated and measurable makes these machines extremely easy to set up and as a result, the end user getting the best results from the equipment.
