Freeze Dryer---PFD Series Industry (With pre-freeze system,Defrosting system,Safety stoppering System,Vacuum Backfilling...)

FEATURES OF PROGRAMMABLE FREEZE DRYER
Automatic Programmable Control System:
From drying To defrosting, user-friendly programmable controls enable you to start runs quickly and the microprocessor controls different ramping and holding segments to meet different temperature protocols.
heated Drying system:
By controlling temperature by forceful circulation of the heat medium of shelf inside, it obtains a further precise distribution of temperatures
pre-freeze system:
The chamber pre-freezes sample to save money and time, eliminating the need for a separate freezer and product transfer.
Defrosting system:
Automatically defrosting system is available for cold tray when defrosting is necessary
Safety stoppering System:
For the purpose of permanent preservation of a sample after freeze of drying ,the stopper system, whtich seals under a vacuum state, consists an option that installs moving guides shelves delicately and that has a function to seal safely and precisely using an oil-hydraulic cylinder.

P CONTROLLER
A.Fully automatic control software from prefreezing to defrosting, digital signature encryption
B.Preset shelf temperature, obtained the eutectic temperature, the triple point temperature, freeze-drying curve.

DRS-DOCUMENTATION SYSTEM(optional)
Documentation system, storage data per minute, continually saving and re-cording 5,250,000 datas for 730 days, with a serial communication module.

RCS-REMOTE CONTROL SYSTEM(OPTIONAL)
1.5km far remote controlling, easy to monitor and control.

Vacuum Backfilling System:
As far as the permanent preservation of the sample desiccation is concerned it protects a sample by inserting sterile nitrogen gas with back filling system for preventing contamination of the sample.
