Large Scale Vacuum Freeze Dryer LLFD-B10

Large Scale Vacuum Freeze Dryer LLFD-B10 is vertical type, cylindrical compact structure. It offers manual and auto control mode, sensor calibration, intelligent temperature control, freeze drying termination reminding and other functions. The temperature ranges from -50℃ to +70℃ and offers 5+1 layers of shelf. Material used AISI 304 stainless steel, top and bottom plate thickness 5 mm. Features CFC Free refrigerant and PT-100 platinum resistance temperature sensor. Designed with refrigeration system, shelf, condenser, vacuum system and liquid circulation system. The heat is transferred to the inner space of the vacuum chamber and absorbed heat during sublimation efficiently. The product is dried completely and evenly.
