Applications

The cooling process with CA system is a storage method when a cooling and CA systems are used together in the same chamber. First, the cooling system cools the chamber down to the core target temperature and then CA system gradually decreases the oxygen (O2) level to a minimum, and keeps the carbon dioxide (CO2) to the maximum level which the fruit can withstand and be stored at. Then, the systems maintain the same level of temperature and gases until the storage period is over and the chamber is open. Compared to a usual cold store, in a cold store with CA conditions many products can be stored from 2 to 4 times longer periods without losing much of its original quality. Therefore, the CA store has a huge advantage, because the quality and freshness of fruit and vegetables can be preserved without any use of any chemicals.

O2Low pest control is a worldwide accepted method of killing insects by using Controlled Atmosphere. The system ensures that the room has the required conditions (such as temperature, gas mix, humidity, etc.), measures, controls and keeps them stable during the whole process. This unique method treatment protocol guarantees 100% mortality of the insects in every stage of their life cycle, from eggs to adults. The method needs a sealed space (like specially built rooms, silos, or gas-tight tents), an oxygen scrubber, and an industrial automation that can record all the important data, make all necessary analyzes, monitor, and maintain the conditions in the chamber.

You can find detailed information on cultivation, pre-harvest, harvest and post-harvest of different fruit types and their storage in controlled atmosphere. OXYCAT provides specialized services in fruit storage especially the storage with Controlled Atmosphere .

Ultra low oxygen (UDO-ULO) is a type of controlled atmosphere that is adjusted dynamically. This technique has different names depending on the refrigeration and various industries that use it. Some of them are ACR, DCA, Dynamic Controlled Atmosphere, CA. These names are actually based on the protocols that are applied. The main machine groups are usually similar or the same. The key point here is how low the O2 level in the environment should be. For this, the environment that will be treated needs to be sealed very well.
