20L Supercritical CO2 Extraction Equipment

20L Supercritical CO2 extraction equipment

20L Supercritical CO2 extraction equipment is a classic CO2 extractor, a best-selling model. Two 10L extractor, design pressure 450bar, maximum working pressure 400bar; separator with maximum working pressure 3L+2L constitutes a separation system, Waxes separation and Light oil separation in 1st separator, To trap lightest and volatile compounds in 2nd separator.

Each batch can process about 2600g of dry materials, and some small factories to extract CBD oil.

It is small batch co2 extraction machine.
