Air blast freezing
Batches of normally packed product are stacked in "tunnels", where high velocity cold air is forced (blown) over the product.

Framework
The all steel welded heavy duty framework is fully hot dipped galvanized for protection and is designed with hygiene in mind, and the whole freezer can be quickly and easily hosed down if required.
Freezing plates
The freezing plates are manufactured from extruded aluminium alloy sections with internal passages for refrigerant.
The freezing plate surfaces coming into contacts with the product are flat and smooth which ensures good contact for heat transfer and high standards of hygiene.
Refrigerant hoses
Flexible refrigrant hoses are connected between the freezing plates and refrigerant headers. The hose consists of a PTFE material covered externally with a double braided stainless steel with stainless steel fittings.
Hydraulic cylinders
Hydraulic cylinders perform the functions of opening and closing the freezing plates.
The provision of twin hydraulic cylinders reduces the overall height of the freezer enabling it to satisfy the low headroom requirements of a fishing vessel.
The cylinders will have stainless steel rods.
Anti-roll bars
Anti-roll bars, designed to retain freezing trays or frames in the freezing stations when plates are open, allow the freezer to be safely loaded and unloaded in the roughest of sea conditions.

Hydraulic cylinders perform the functions of opening and closing the freezing plates and raising the lowering the lifting arms. The hydraulic cylinders will have stainless steel rods.
Lifting arms
The horizontal and vertical members of each lifting arm are fitted with a high density polyethylene extrusion, forming the bottom of the freezing station.

Designed and created by Cospolich to meet the demand for large cold-storage spaces, ARCTIC SAFE offers many advantages, even in situations that present installation and operational challenges.
CONSTRUCTION
In its construction, ARCTIC SAFE continues the Cospolich reputation for strength and beauty. Heavy-duty marine-quality doors, latches, and hinges assure that "wear points" are minimized. Wall panels are reinforced with 4" foamed-in-place polyurethane, further supported by full perimeter molded dense urethane support system hardrails, and all is encased in .035 stainless steel. The floor is .060 stainless steel, reinforced with a rigid underlayment, and is capable of supporting 2500lbs. per square foot.

Exterior and interior of all standard cabinets, including front, sides, doors and louvered grill are constructed of heavy gauge, type 304 stainless steel.
Special attention was taken in engineering the doors of the Cospolich cabinet. The door unit was designed to withstand the continuous use and abuse that is common in all food service applications.
Resilient vinyl gaskets which are pre-formed in frames with welded corners, greatly inhibit bacterial growth and are easily replaceable.
Heaters, which are concealed under the thermal breaker strip around the door perimeter, prevent condensation.
