Container Blast Freezer Unit: MODEL CBU-30 

Klinge's Blast Freezer Model CBU-30 is primarily used for the quick freezing of yellowfin tuna, other high-value seafood and meat. Our picture frame style freezer is designed for freezing cargo to -60°C (-76°F). It is mounted to 20’ or 40’ ISO containers or trailer bodies.

More and more companies are using lower temperature freezing machinery to transport high value seafood and meat. This is because blast freezing means substantially reduced transportation costs as the fish can be transported by container ship rather than air freighted.

The CBU-30 is also unique in that its evaporator fan draws air through the load to ensure even temperatures throughout the load. Many standard units are not equipped with an evaporator fan system designed to accommodate cargos with high-pressure drops.

Without the special design, airflow would be reduced and the blast freezing process would take considerably longer.
