The SFE Pro Supercritical CO2 Extractor

This is Green Mill's premiere supercritical CO2 extraction system, with full automation, and the most power for its footprint in the market. Designed for ease of use, consistent results, and repeatability. Software monitors and controls the entire extraction process, including flow rate, pressures, temperatures, and time. Touch panel interface means no knobs to turn or switches to flip.

 
  • Pressure: 7,500 psi
  • Base price: $165,000

Automation

After you press the Start button, the system runs itself. Other systems claim to be automated, but take a closer look and it's often not true. Our system switches extraction vessels for you, maintains all pressurizing and depressurizing, and has a built-in clean cycle. Heater blocks at valve outlets prevent clogging.

Vessels

When accessing your pressure vessels, simply open and close the high quality plugs with oversized threads by hand — no need for tools. You will shorten down-time between runs and limit wear and tear on parts.

Highly Selective Fractionation

You'll achieve a large variety in the types of product you can create in a single run, thanks to increased residence times made possible by three large collection vessels with independent pressure and temperature controls.

Heat Exchanger

High power, high efficiency heat exchanger pre-heats the CO2 for more stable temperatures in your extraction vessel.

Pump

We custom designed our own liquid displacement pump with the integrity of your product in mind. Four pistons means more consistent flow output, which means more stable conditions throughout the system, resulting in consistent, repeatable performance. Wear and tear is reduced by running lower RPMs. No pre-compressor or 3-phase power required, avoiding high-cost installations.

software

You won't find a simpler, easier operating experience thanks to Green Mill's PC-based software, which allows you to create, save, select and run your recipes. We chose PC over PLC because of increased programmability and flexibility. Review your post extraction system performance with comprehensive data logging. Maximize your extractions with automatic density calculations and feedback.

Dispersion Plate (Patent Pending)

This specially designed dispersion flow plate helps prevent pockets of "dead flow," maximizing the yield from your extractions. Reduced channeling means maximum extraction efficiency as all plant material comes into contact with CO2.
