Carbon dioxide injection for reefers

Carrier Transicold’s EverFRESH controlled-atmosphere system for refrigerated containers offers carbon dioxide (CO2) injection to preserve low-respiring, high-value perishables

Carrier Transicold’s EverFRESH 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.

“The option is beneficial for cherries, blueberries, grapes, papayas and other low-to moderate-respiring commodities that do not create a lot of CO2on their own,” said Jim Taeckens, senior product manager, Global Container Refrigeration, Carrier Transicold.

“This technology allows customers to better protect and extend the shelf life of high-value commodities, which is especially important.”

Using active controlled-atmosphere technology, the EverFRESH system balances the oxygen and CO2 within a refrigerated container to reduce respiration and slow natural ripening. It generates 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 systems.

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-Link5 controller.

Container atmosphere levels can be securely monitored via a mobile device using Carrier Transicold’s DataLINE Connect app. Carrier Transicold’s TripLINK data management platform can be used to set and monitor oxygen and CO2levels.

TripLINK will continue to be further enhanced by Carrier’s new Lynx digital platform, which provides application support to expand automation capabilities.
