Carrier Transicold has launched a new CO2 injection option for its EverFRESH active controlled atmosphere system for refrigerated containers to help better preserve low-respiring, high-value perishable cargo.

The new option allows the container to be pre-charged with CO2 at the start of the voyage and automatically add more over the course of the trip.

As the only container refrigeration system manufacture to offer a system of this kind, the new option serves as an example of how Carrier aims to innovate its products and services as part of the Healthy, Safe, Sustainable Cold Chain programme.

The programme’s goal is to preserve and protect the world’s supply of food and medicine.

Jim Taeckens, senior product manager, global container refrigeration, Carrier Transicold, said: “The option 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.”

The EverFRESH system, using active controlled-atmosphere technology, optimises the balance of oxygen and CO2 with 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 oxgen.

It maintains a positive pressure within the container which Carrier claims makes it less sensitive to box leakage than other controlled-atmosphere methods.

The EverFRESH system with CO2 injection is available as a factory installed option for Carrier Transicold PrimeLINE refrigeration systems equipped with the wireless Micro-Link 5 controller.

Using the DataLINE Connect app, container atmosphere levels can be monitored via a mobile device.

Additionally, Carrier Transicold’s TripLINK data management platform can be used to set and monitor oxygen and CO2 levels.
