Klinge Corp’s Blast Freezer Container, 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 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 cargoes with high-pressure drops.
Without the special design, airflow would be reduced and the blast freezing process would take considerably longer. Contact a Klinge Group Specialist Today!

FEATURES OF BLAST FREEZER UNIT (MODEL CBU-30)
» Designed for freezing cargo from -20ºC to -60ºC (-4ºF to -76ºF).
» High capacity ideal for freezing meat and seafood.
» Full Airflow: Even in loads with a very high cargo internal pressure drop.
» Unique Design: Many standard units are not equipped with an evaporator fan designed for cargos with high pressure drops.
» Even temperatures throughout cargo.
» Efficient Airflow: Evaporator fan and adjustable ceiling provides efficient airflow control, which is essential for quickly lowering cargo temperature.
» Convenience: Blast freezers can be used in containers or trailer bodies.
The new and improved CBU-30 false ceiling allows for even faster blast freezing by ensuring that the
maximum airflow is pulled across your cargo. This ensures quicker cooling and less overall power use
