Good practices for Controlled Atmosphere (CA) preservation

In this article, ABSOGER examines best storage practices in CA chambers to help you identify critical points.

Ensure chamber tightness

CA chambers must be sufficiently airtight to prevent oxygen from entering. Gerbaud Isolation's team provides maintenance and tightness testing services to ensure the quality of your facilities.

Control CA equipment

Before filling your chambers, ensure that equipment such as nitrogen generators, CO2 absorbers, and analyzers are in good working condition.

Do not mix different types of packaging

Plastic and wooden crates have different dimensions and thermal conductivity. This can cause air distribution imbalances in the chamber. It is recommended not to mix these two types of pallets.

Monitor safety devices installed in your chambers

Storage chambers require various safety measures to protect products and equipment. It is important to periodically inspect elements that ensure the safety of your CA chambers, such as pressure relief valves, hydraulic guards, compensation tanks, and CA doors. Checking the proper functioning of the chamber closing system and the presence of warning signs is essential to ensure people's safety.

Annual calibration and maintenance

Regular verification and calibration of oxygen (O2), carbon dioxide (CO2), and ethylene (C2H4) analyzers are essential to ensure their accuracy. Contact the ABSOGER team for annual and preventive maintenance of this equipment. This approach ensures reliable measurements and optimal preservation of your perishable products.

Use the ABSOGER proportional regulation system for longitudinal monitoring

Integrating ABSOGER SUPERVISOR V7 into your preservation system allows for precise atmosphere regulation and continuous longitudinal monitoring.

Periodic comparative measurements

To ensure optimal storage conditions, it is crucial to periodically measure gas levels (O2 and CO2) and take temperatures. ABSOGER offers a portable O2 and CO2 analyzer for this monitoring. Daily checks of cold running time help ensure proper functioning.

Ethylene removal

Ethylene, a gas naturally produced by fruits and vegetables, should be removed from the beginning of the cooling process. Ethylene can accelerate the ripening and deterioration of products, so effective control is essential. Use an ABSOGER C2H4 analyzer and C2H4 catalyst to analyze and control ethylene levels in your rooms and maintain optimal levels.

Prioritize ULO and XLO storage

Low oxygen storage is essential for ensuring a long shelf life. The new dynamic pressure regulation system allows for extremely low oxygen levels in any type of new or existing chamber. ABSOGER, an expert in preservation, offers customized solutions to ensure the quality of your products throughout their storage.
