In a ULO or CA room the amount of oxygen and in some cases the amount of carbon dioxide is reduced. By decreasing the amount of oxygen in the ULO room − and with CA storage also the amount of CO2 − to the recommended level for the crop, products in stock, also called fruit storage, are contained in a controlled manner for a long time.
ULO and CA cells are often used by companies in the food industry that want to store different types of products in a controlled manner for a long time. The fruit and vegetable products contained in this fruit storage cannot be stored in 'normal' cold rooms or freezer rooms for a longer period of time because they will deteriorate
. The controlled oxygen, carbon dioxide and nitrogen ensure that the products can be stored longer.
Due to the controlled hygienic air in these ULO and CA rooms, it is very important that this air is not polluted. In these cases, a gastight CA door offers the best solution for your fruit storage.
CA and ULO areas are extremely suitable for the delayed ripening of vegetables and fruit, also known as fruit ripening. Storing fruit and vegetables in a CA room or a ULO room has the advantage that these can be stored for up to a year longer. This is done by putting the products to sleep through the reduction of oxygen and carbon dioxide. This will stop the fruit ripening and keep the products fresh for longer.
With the delayed fruit ripening, it is important that no gases can escape from the ripening room, so the oxygen and carbon dioxide values remain as constant as possible. The more constant these values remain, the better the quality of the products is preserved. In addition, the more gas escapes
from the ripening room, the more energy it takes to maintain these values again.
To prevent this, you can opt for a robust, reliable door
that ensures your CA or ULO ripening room is completely gastight. The Metaflex CA door is fitted with high-quality hinges and locks, so the door closes firmly and remains closed.
