Reach Pre‐Vacuum Value & Time
In Program Temperature Control mode:It is allowed to set max. 18 sections of temperature
control program. After temperature control program finishes running, it skips into Secondary
Drying Stage. In this mode, it is allowed to create formula and material name, delete, upload or
download the formula.
In Vacuum Control Mode: When present vacuum is less than vacuum lower limit,it starts
heating. When vacuum exceeds vacuum upper limit, it stops heating.
When initial drying time is finished, it skips into Secondary Drying stage. If present vacuum≤
keeping/maintaining pressure, and also reaches keeping/maintaining time, it skips directly into
Secondary Drying stage without finishing remaining time at initial drying stage
Temperature upper limit: It is the maximum temperature allowed for shelf heating in the Initial
Drying stage.
Secondary Drying Time: It is running time in the Secondary drying stage. After
secondary drying time is finished, the vacuum pump stops running and it enters into
heat‐keeping/maintaining stage
Heat‐Keeping/Maintaining Temperature: It is shelf control temperature in
Secondary Drying stage.
Heat‐Keeping/Maintaining time:
It is designed to stop heating and keep refrigeration in case the freeze dryer is
unattended after freeze drying program is finished.
