Co2 Scrubber

Product Details:

Despite being in a "dormant" state as a result of being cold and deprived of Oxygen, the fruit will continue to breathe (albeit at a reduced rate) and will continue to produce Carbon Dioxide (CO2). Allowed to build up unchecked, high concentrations of CO2 will cause damage to the fruit. It is therefore essential to monitor levels, and to take action to remove excess levels of CO2 as they occur.

The CO2 Adsorber (or scrubber) draws air from the store and filters out CO2 before pumping it back into the store. By circulating the air in this way, the air returned to the store maintains the important low oxygen conditions.

The Adsorber works by passing the air through a bed of carbon, which attracts and holds the CO2 molecules. Periodically, the machine flushes out the carbon bed by pumping air through it in a reverse direction and venting to the outside, thus there is very little expense in terms of consumables or costly maintenance.

Generally, one Adsorber will be connected to a number of stores, treating each one in rotation via a series of valves. The operation of the machine is controlled by an internal or external analyzer, which samples air regularly from each store.
