Carrier Transicold’s EverFRESH active controlled-atmosphere system for refrigerated containers now offers a new carbon dioxide (CO2) injection option to better preserve low-respiring, high-value perishable cargo.
The new option allows the container to be pre-charged with CO2 at the start of a voyage and automatically add more over the course of the trip.
Carrier Transicold is the only container refrigeration system manufacturer to offer a controlled-atmosphere system with an integrated option to add CO2 on demand.
Jim Taeckens, senior product manager, global container refrigeration at Carrier Transicold, said the system is beneficial for cherries, blueberries, grapes, papayas and other low- to moderate-respiring commodities that do not create a lot of CO2 on their own.
“This technology allows customers to better protect and extend the shelf life of high-value commodities, which is especially important,” he said.
Using active controlled-atmosphere technology, the EverFRESH system optimizes the balance of oxygen and CO2 within a refrigerated container to reduce respiration and slow the natural ripening of the commodity by generating high-purity nitrogen to more quickly and responsively displace oxygen.
The system maintains a positive pressure within the container, making it less sensitive to box air leakage than other controlled-atmosphere methods.
The EverFRESH system with CO2 injection is currently available as a factory-installed option for Carrier Transicold PrimeLINE refrigeration systems equipped with the wireless Micro-Link 5 controller.
Container atmosphere levels can be securely monitored via a mobile device using Carrier Transicold’s DataLINE Connect app, and Carrier Transicold’s TripLINK data management platform can be used to set and monitor oxygen and CO2levels.
