UNIFLUID TM system SERAIL is the original inventor manufacturer with UNIFLUID TM . With UNIFLUID TM a primary “cold“ loop and a secondary “hot and cold“ loop achieve the thermal functions of the freeze-dryer. UNIFLUID TM allows a complete specialization of these two loops giving you maximum flexibility and dependability. This UNIFLUID TM technology applied to industrial freeze-dryers offers the following unique advantages: - Perfect temperature control in all shelves and condenser. - Precise checking of sublimation speed. - Homogeneity in trapping ice in the condenser. - Quickness and efficiency during cooling operation both for shelves and condenser after sterilization and defrosting. - Improved freezing speed by using the cold accumulator facility. - Compactness and standardization of refrigeration units:   •Easy layout •Easy maintenance   - Elimination of long refrigeration loops and related problems:   •Oil returns troubles •Layout restraints   Cascade
