Carrier Transicold’s new XtendFRESH™ container atmosphere control system uses innovative technologies to help maintain the quality of shipped produce, while extending shipping distances to enable growers reach new customers. Considering its many benefits, the XtendFRESH system is designed to be more affordable than Carrier’s prior atmosphere control solutions and relatively easy to install on existing equipment.
“The XtendFRESH system will expand opportunities for the global trade of perishable commodities,” said David Appel, president, Carrier Transicold. “It will enable Carrier Transicold’s shipping line customers to help exporters extend their reach into new markets.”

The XtendFRESH system actively controls oxygen (O2) and carbon dioxide (CO2) levels and removes ethylene, a hormone given off by ripening produce that will accelerate ripening if left unchecked. O2 and CO2 levels can be independently set at levels that produce optimum results for a given commodity. The system’s ability to remove ethylene, while managing O2 and CO2, is key to its performance and distinguishes it from other products for container atmosphere control.
By slowing ripening, XtendFRESH significantly lengthens the amount of time produce can spend in refrigerated transit – by more than double in some cases. For example, bananas can be shipped for up to eight weeks rather than four, and beans for up to four weeks rather 10 days.
The XtendFRESH system has a patented self-regenerating activated carbon scrubber assembly that removes ethylene and CO2 created by the ripening processes occurring inside the container. As O2 is consumed by ripening produce, automated, on-demand fresh-air ventilation helps maintain the optimum O2 level for the specific cargo inside. No other product integral to the container actively manages CO2 and O2 and removes ethylene. O2, will typically be managed to a range of between 3 to 21 percent, and CO2, will typically be managed within a range of zero to 19 percent.
Modular by design, the XtendFRESH system can be easily added to existing Carrier container refrigeration units equipped with the Micro-Link® 3 (ML3) controller. Key components include the scrubber assembly, a ventilation panel with integral blower, control software and sensors for monitoring O2 and CO2. Adding a humidity sensor provides additional atmosphere control, enabling humidity to be reduced to as low as 50 percent, as needed for cargo protection.
The XtendFRESH system is currently completing trials and Carrier Transicold anticipates availability later this year.
