Carrier Transicold introduced SimplyFRESH, a passive controlled atmosphere system designed to protect perishable cargo on refrigerated container voyages of fewer than 20 days by continuously monitoring and controlling CO2 levels while providing real-time data through their Lynx Fleet telematics platform.
- Purpose: SimplyFRESH is a passive controlled atmosphere system designed for refrigerated container voyages of fewer than 20 days, complementing Carrier Transicold's active EverFRESH system for extended voyages up to five weeks.
- How it works: Sensors continuously monitor CO2 and O2 levels, maintaining CO2 within ±0.2% of the operator-set range (1-19%), while an O2 safety override protects cargo from anaerobic damage.
- Ideal cargo: Best suited for climacteric produce like mangoes, bananas, and avocados, and can support shorter routes for non-ripening fruits like blueberries, cherries, and grapes.
- Cost benefits: Introduces fresh air only when needed, reducing cooling demand and limiting coil icing, making it a cost-effective alternative to full active CA systems.
- Data monitoring: Connects to Carrier Transicold's Lynx Fleet telematics platform to log and stream CO2, O2, and humidity data for real-time monitoring and voyage reporting.
Carrier Transicold introduced SimplyFRESH, a passive controlled atmosphere (CA) system designed to help protect perishable cargo on shorter refrigerated container voyages.
“Not every perishable shipment needs a full active CA system. For shorter voyages, customers need reliable carbon dioxide (CO2) control, a clear record of conditions and a cost-effective solution,” says Rob Veltman, associate director, product management and global postharvest commercial lead, Carrier Transicold. “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.”
Key takeaways:
· Developed for refrigerated containers on voyages of fewer than 20 days, SimplyFRESH controls CO2 levels to protect perishable cargo. It complements, rather than replaces, Carrier Transicold’s EverFRESH active CA system, which supports extended voyages of up to five weeks. SimplyFRESH is particularly suited for climacteric produce, such as mangoes, bananas and avocados.
· It can also support shorter-route applications for non-ripening fruits such as blueberries, cherries and grapes, depending on the atmosphere requirements and shipment profile.
· Sensors continuously monitor CO2 and oxygen (O2) inside the container. Operators set a CO2 setpoint between 1-19%. When CO2 rises above the selected range, the system introduces outside air through the fresh-air valve and releases excess pressure, maintaining CO2 levels within ±0.2% of the setpoint.
- An O2 safety override automatically opens the fresh air valve when O2 falls below 3%, helping protect cargo from anaerobic damage.
- The system introduces fresh air only when CO2 levels require it, limiting the amount of outside heat entering the container, which can reduce cooling demand and help limit coil icing.
- SimplyFRESH works with PrimeLINE and OptimaLINE units equipped with the Micro-Link 5 controller.
- The SimplyFRESH system connects to Carrier Transicold’s Lynx Fleet telematics platform. It logs CO2, O2 and relative humidity throughout the journey and streams the data to the platform for real-time monitoring and voyage reporting.
