Carrier Transicold Adds Versatility to EverFRESH Active Controlled-Atmosphere System to Extend Shelf Life of Perishables


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. Carrier Transicold is a part of Carrier Global Corporation (NYSE: CARR), a leading global provider of healthy, safe and sustainable building and cold chain solutions.

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. container refrigeration system manufacturer to offer a controlled-atmosphere system with an integrated option to add CO2 on demand. This addition to the EverFRESH system is an example of how Carrier continues to innovate its products and services as part of the Healthy, Safe, Sustainable Cold Chain Program to preserve and protect the world’s supply of food and medicine.

“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,” 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 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 CO2 levels. TripLINK will continue to be further enhanced by Carrier’s new Lynx™ digital platform, which provides application support to expand automation capabilities.
