The 1lb Bi-Directional closed loop increases efficiency by utilizing both a bottom and top solvent input. By using a bottom flood on the first wash to ensure all material has seen solvent, preventing channeling through the material. Finish the run with a top flood input to ensure all residuals have been washed from the material. Oil bearing solvent is collected in the collection base under the material column. Once collected, solvent is distilled and recovered, leaving the oils in the collection base. This is a passive unit that utilizes pressure differences created by manipulating temperature to move solvent. This unit can be upgraded into an Active recovery unit by purchasing the upgrade kit.
