Freezing equipment refers to specialized systems designed to rapidly lower the temperature of food products to sub-zero levels, preserving texture, yield, and shelf life. In seafood processing, the choice of freezer directly affects the commercial value of every batch leaving the line.
NorMar offers a wide range of used and refurbished freezing equipment from established manufacturers such as DSI, Frigoscandia, Jackstone, Scanico, Starfrost, Geneglace, Güntner, Lu-Ve, and Danfoss — covering plate freezers, IQF and spiral freezers, ice generators, and supporting refrigeration components. All machines are inspected and overhauled in our workshop in Norway before delivery.

Flow freezers (also known as tunnel or continuous freezers) move product through a freezing chamber on a conveyor belt under high-velocity cold air. They are a standard choice for high-volume freezing of fish, shrimp, prepared meals, and vegetables.
Example: Frigoscandia MX 32.
A variant of the flow freezer with a helical conveyor, which dramatically reduces floor space for a given residence time. Widely used for value-added products, breaded items, and salmon portions — see for instance the Spiral Freezer Scanico / Thermofin.
Horizontal plate freezers (HPF) freeze product packed in cartons or trays between hydraulically closing refrigerated plates, producing dense, uniform blocks with high energy efficiency. They are the standard solution for HG fish, fillets in cartons, shrimp, and by-products.
Examples: DSI HPF 12-14 Horizontal Plate Freezer, Tucal Horizontal Plate Freezer.
Vertical plate freezers (VPF) are designed for unpacked, bulk freezing of pelagic species — herring, mackerel, capelin, blue whiting — as well as whitefish off-cuts and shrimp. Product is loaded directly between vertical plates and frozen into clean 25 kg blocks, ready for glazing and palletizing. Common both onboard fishing vessels and in shore-based pelagic plants.
Examples: DSI V5 28-75 B Vertical Plate Freezer, Jackstone Vertical Plate Freezer.
IQF (Individually Quick Frozen) freezers freeze each piece separately, so the product remains free-flowing in the bag. The fast crust-freezing preserves cell structure and limits drip loss on thawing, making IQF the preferred method for premium shrimp, salmon portions, scallops, and berries.
Example: Frigoscandia Midget-Gyre.
Ice generators produce flake, plate, or tube ice for chilling raw material and finished products throughout the seafood chain — from landing to final packaging. Capacity is typically rated in tonnes of ice per 24 hours.
Example: Geneglace F900.
A freezer is only as reliable as the refrigeration system behind it. NorMar also supplies condensing units, air coolers, and other components compatible with common industrial refrigerants such as ammonia (R717), CO₂ (R744), and R404A — including units from
Lu-Ve, Danfoss Optyma Plus, and Güntner.
