Our patented Valveless Expansion Technology features a uniquely fabricated device that decompresses the mixture of CO2 and extracted oil in such a way that enhances the flow of CO2. (Decompression must take place before the separation process.) Because there are no valves where the separation occurs with the Valveless Expansion Technology, there is no clogging of material or obstruction in the flow of liquid CO2. The enhanced flow of CO2 speeds up the extraction process.
Competitive systems typically use some kind of a needle or throttle valve with small passages and machined details that can collect oils which ultimately cause clogging and possibly system shutdowns wasting time and labor.
