Carrier Transicold's SimplyFRESH Brings Passive CA Control to Sub-20-Day Container Voyages

Carrier Transicold has introduced SimplyFRESH, a passive controlled-atmosphere (CA) system targeting refrigerated container voyages of fewer than 20 days. Commercial availability is planned for 2027.

How the system operates

SimplyFRESH uses continuous CO₂ and O₂ sensors to maintain a user-selected CO₂ setpoint between 1% and 19%, holding levels within ±0.2% of the target by introducing outside air only when CO₂ control requires it. An O₂ safety override automatically opens the fresh-air valve if oxygen drops below 3%. By limiting fresh-air intake to the periods when CO₂ regulation demands it, the system can reduce cooling demand and help limit coil icing.

Cargo scope and positioning

The system is designed for climacteric produce such as mangoes, bananas and avocados, and can also support shorter shipments of blueberries, cherries and grapes, depending on atmosphere requirements. It complements Carrier Transicold's EverFRESH active CA technology, which supports voyages of up to five weeks.

Compatibility and deployment

SimplyFRESH is compatible with PrimeLINE and OptimaLINE refrigeration units equipped with the Micro-Link 5 controller. Integration with the Lynx Fleet telematics platform provides 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.

Rob Veltman, Associate Director of Product Management and Global Postharvest Commercial Lead at Carrier Transicold, noted that the system was designed for this specific 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. The company will showcase SimplyFRESH at Intermodal Europe 2026 in the Netherlands on November 10–12, at Booth C50.
