Serec's patented Airless™ technology can be used in state-of-the-art solvent extraction and reclamation systems, either standalone or as a module in a process line. Our use of a high vacuum, low temperature airless chamber enables our machines' performance to exceed that of our competitors.

Vacuum technology is fully utilized in Serec solvent extraction systems in the following three areas:

Solvent Emission Reduction — Initially the air in the cleaning chamber is evacuated so that the solvent and the air are not interfaced with each other to eliminate the solvent emissions.
De-gassing the Solvent — When the solvent is placed under vacuum, the air dissolved in the solvent is eliminated to enhance the ultrasonic power - this means cleaner parts.
Drying the Parts Completely — In the vacuum drying process, the vacuum is created in the cleaning chamber. The higher the vacuum, the lower the solvent boiling point becomes. The heat capacity of the parts helps boil the solvent and the evaporated vapor is recaptured and recycled in the system. In case of methylene chloride, the boiling point at atmospheric pressure is about 40°C, whereas, at 80 torr it boils at - 10°C.
