Its a 150 gallon tank with 2 temperature controlled shelves. Using a polyscience ad15, you can control the temperature to a very precise measurement from -25 c to 200 c depending on compatible fluids.
This system can be used for a wide variety of tasks. Obviously freeze drying is the discussion at hand. I would set the polyscience to -5 c and pull a vacuum for 18-24 hours.
The vacuum pulls from above the cold trap which also has a drain valve for the condensate. There is a gas port which allows you to flow inert gas to maintain a desired environment in the chamber. Pressure relief valves ensure you don’t go past the 80 psi mark.
Easy access manhole doors make it similar to opening a vacuum oven.
Any questions?
