Ultraflow / Impingement Freezer

Dantech’s Ultraflow Freezer is available in two versions: the Ultraflow Max and the Ultraflow Super Hygiene. The Ultraflow Max offers customers an encapsulated tunnel freezer within a full cabinet. The Ultraflow Super Hygiene has a hooded cabinet that can be hoisted for easy access and cleaning.

Ultraflow / Impingement Freezer


The Ultraflow® Tunnel Freezer operates with the very effective and fast principle of impingement airflow. This is based on the innovative airflow made by Dantech that freezes the products with rapid speed. The air is directed from a pressure chamber through small nozzle outlets on the top and bottom of the product.

This results in very high air speeds being achieved and ensure an extremely rapid heat removal from the product. Furthermore, the air flows over the product – similar to the principle of an aircraft wing – under “Coanda effect” and forms a streamline coating. As a result, the product is completely encompassed by surrounding air. The product is gently and evenly cooled from above and below; thereby building an evenly distributed layer of cold air.
