TK FRESH is a perishable foods guidebook for AFAM+ / TK FRESH+. TK FRESH contains various recommendations on oxygen and carbon dioxide levels that should be mechanically maintained in refrigerated containers to preserve fruits and vegetables in ocean voyages. Thermo King Corporation publishes these guidelines to assist its customers and others in the shipping industry in the operation of refrigerated containers equipped with Advanced Fresh Air Management ("AFAM+ / TK FRESH+").

AFAM+ / TK FRESH+ operators should understand that the oxygen and carbon dioxide levels recommended herein, and predictions made on the loads' responses to a change in gas levels, are merely guidelines, rather than hard science. Food responses vary with container temperature and also depend upon product condition, load mix, packaging, time in transit and storage, different maturities or ripeness stages, varieties, growing regions, growing conditions and previous storage history. Consequently, the guidelines must be adjusted when new conditions and/or prior product history dictate.

The product setting guidelines contained in TK FRESH were compiled from highly regarded sources and research. Every reasonable effort was made to provide reliable data and guidelines. However, Thermo King Corporation and publisher disclaim any liability or responsibility for the accuracy of the guidelines or shipping results achieved at these settings, and any use of TK Fresh and the guidelines contained therein is at your sole risk and responsibility.
