Rapid freezer for Plasma on contact RAPIDITY FREEZING the bag is in contact with the surfaces of the wells and intense extraction of thermal energy is obtained in this manner, minimizing in this way the freezing time: < 45 ‘ for 24 (450 ml.) nominal standard bags, with a net content of plasma of at least 230 cc. and an initial temperature between + 25°C and + 30°C KW has undertaken tests with bags with a mass of 260 gr. each. Besides, in many experiences, made in hospital laboratories, with full charged freezer, were evaluated times of 55’ for 400 mL charge of plasma, 60’ for 600 mL charge of...

Rapid freezer for Plasma on contact The expansion of the refrigerating fluids is obtained using special thermostatic valves; the evaporators made up of serpentine tube in cooper thermally connected – to the entire external peripheral surface of the freezing wells. The solution, together with the use of tanks for refrigeration, guarantees: • a great reserve of liquid, a consecutive fast response to the cold request in the act of introducing the bags and therefore a high refrigerant capacity (very rapid freezing) • high internal temperature uniformity. The entire thermofluidodynamic circuit is...
