An installation and method for freezing and cold storage of palletized product. A chiller is provided in the interior of a cold storage warehouse space that maintains the temperature of ambient air within the space below freezing. A plurality of racking structures each define an air flow chamber having air intake openings on opposite sides thereof and an air outlet to enable freezing air to be drawn into the chamber through the intake openings and exhausting into the warehouse space. Pallets on pallet guides are pressed against the intake openings such that freezing air is drawn through the palletized product to thereby quickly freeze the product. The pallet structure and air flow chambers are arranged in spaced-apart rows to enable a forklift to pass down the aisles so as to place and remove the palletized product.
