- Next-generation active controlled-atmosphere systems are being utilized in refrigerated cargo fleet to enable perishable shipments to travel farther while retaining quality
- Active injection technology allows the refrigerated container to be pre-charged with CO2 at the start of a voyage and to automatically add more during the trip
Container shipping line Cosco Shipping Lines recently enhanced its refrigerated cargo fleet with a high-precision controlled-atmosphere system to extend the shelf life of a wide range of perishables.
The carrier said it is now utilizing the next-generation EverFRESH active controlled-atmosphere (CA) systems from Carrier Transicold for its refrigerated cargo fleet to enable perishable shipments to travel farther while retaining commodity quality.
“The next-gen EverFRESH units will maintain atmosphere at precise points to sustain produce quality and extend shelf-life for a wide range of perishables,” said Suresh Duraisamy, associate director for global container refrigeration at Carrier Transicold.
“The systems provide the quality our customers have come to expect, with new technology that builds on the first-generation EverFRESH units’ robust design and proven performance, to propel their fleets into the future.”
Using active CA technology, the system optimizes the balance of oxygen and carbon dioxide (CO2) within a refrigerated container, slowing respiration and the natural ripening of the commodity inside.
It also generates high-purity nitrogen to more quickly and responsively displace oxygen, rather than relying on cargo respiration alone to gradually reduce oxygen levels.
It also maintains a positive air pressure within the container, making it far less sensitive to box leakage than other types of systems.
The improved CA system “allows us to handle a broader range of perishable commodities across the globe, and confidently protect and ship them to newer and further markets for our customers,” said Chen Yang, manager of sales and marketing for reefer trade at Cosco Shipping Lines.
The system has an active injection technology that allows the container to be pre-charged with CO2 at the start of a voyage and to automatically add more over the course of the trip.
Carrier Transicold is the only container refrigeration system manufacturer in the market today offering a CA system with an integrated option to add CO2 on demand. The company is a part of Carrier Global Corporation, the leading global provider of healthy, safe, sustainable and intelligent building and cold chain solutions.
