Carrier Transicold has introduced SimplyFRESH, a passive controlled atmosphere (CA) system designed to protect perishable cargo during refrigerated container voyages of fewer than 20 days. The system controls carbon dioxide (CO2) levels and offers an alternative for shipments that do not require full active atmosphere control. Commercial availability is planned for 2027.
SimplyFRESH is designed for climacteric produce, including mangoes, bananas and avocados. It can also support shorter shipments of blueberries, cherries and grapes, depending on atmosphere requirements. The system complements Carrier Transicold’s EverFRESH active CA technology, which supports voyages of up to five weeks.
Sensors continuously monitor CO2 and oxygen (O2) inside the container. Operators can select a CO2 setpoint between 1% and 19%, with the system maintaining levels within ±0.2% of the target by introducing outside air when required. An O2 safety override automatically opens the fresh-air valve if oxygen falls below 3%. By limiting fresh-air intake to periods when CO2 control requires it, the system can reduce cooling demand and help limit coil icing.
SimplyFRESH is compatible with PrimeLINE and OptimaLINE refrigeration units equipped with the Micro-Link 5 controller. Integration with Carrier Transicold’s Lynx Fleet telematics platform enables real-time monitoring and voyage reporting, including logged CO2, O2 and relative humidity data. The system will be offered as a factory-installed option and as a retrofit for compatible existing units, with aftermarket installation available worldwide.
“SimplyFRESH was designed for that use case, giving operators the flexibility to match controlled-atmosphere technology to the cargo and voyage rather than applying the same solution to every shipment,” said Rob Veltman, Associate Director, Product Management and Global Postharvest Commercial Lead at Carrier Transicold. The company will showcase the system at Intermodal Europe 2026 in the Netherlands on November 10–12, at Booth C50.
