IQF tunnel freezers

Cryogenic tunnel cooling, chilling, and freezing are ideal for continuous food processing.

The method is used in a wide range of industries, from bakeries to manufactures of fish, poultry, and red meat as well as fruit & vegetable producers.

All of our cryogenic tunnel solutions are designed to minimize the cost per kg of treated product and to ensure low kW consumption as well as a high yield. Factors that add up to ensure a small carbon footprint in your production. Our design also ensures easy cleaning, maintenance, and a long service life. Our cryo tunnels are based on the same process, where food is transported through a tunnel while immersed in very cold liquid nitrogen or sprayed with extremely cold LN2 or CO2 gas.

Our cryogenic tunnels are produced in stainless steel to meet the international hygienic requirements and adhere to all USDA and OSHA guidelines. They are UL508A and CE certified, and on top of that, the freezers represent a low capital investment with quick installation and small footprint.

Our range of tunnel solutions cover a linear tunnel freezer, multipass tunnel freezer, multibelt tunnel freezer, and an immersion tunnel freezer.
