Factory price freeze dryer/vaccum lyophilizer/vacuum freeze dryer machinery

Technical advantages: 1. Vertical cylindrical condenser,compact structure,with good water capture capacity, no dead corner, easy for defrosting and cleaning. 2. Refrigeration system protection control device: adopt international famous brand products, accurate, stable, safe and reliable. 3. High pressure protection system: when the system exhaust pressure more than allowed, refrigeration unit running will be automatically cut off , to prevent accidents. 4. Middle pressure regulation system: in the double-stage refrigeration system, proper middle pressure are very important for operation performance and life of the refrigeration system. When middle pressure below the set value, the system will automatically start to adjust. Create conditions for the realization of the lyophilizer unmanned operation. 5. Oil pressure protection system: when the long time operation of the refrigerator, monitor the hydraulic pressure of the refrigerator, prevent refrigerator damage because of oil lack. 6. The motor temperature protection system: when the refrigerator motor temperature higher than the set value, in order to protect the refrigerator, the system will automatically stop the operation of the refrigerator. 7. Oil return at low temperature regulating system: when refrigerator works under very low evaporation temperature for long time , how to make the refrigeration oil well back to the crankcase is very important (lack of refrigeration oil in the system often causes refrigerator "burned"). When the crankcase lack of refrigeration oil, the system automatically start to establish proper oil level in the crankcase. Create conditions for the realization of the lyophilizer unmanned operation. 8. Exhaust temperature control system: when refrigerator exhaust temperature is too high, the system automatically start cooling system, to prevent the high pressure part of overtemperature operation. Create conditions for the realization of the lyophilizer unmanned operation. 9. Wet stroke prevention control system: when the high load operation of the refrigerator, the system can automatically go in the process of adjustment, prevent the wet stroke even "liquid impact phenomenon". Create conditions for the realization of the lyophilizer unmanned operation. 10. Automatic liquid collection device: when the refrigerator is in standby mode, the device will automatically run , to collect stranded refrigerant in the system to storage tank, in order to start the freeze dryer again. 11. The machine start protection: when equipment has all security conditions , the machine will be able to start running. 12. whole machine structure longitudinal, front and back split type (convenient for transport and placing ). 13. Ozone disinfection function is optional.
