Closed Loop Reclamation Extraction System
(Comes with 1 yr. Limited warranty)
Please Read Optional Upgrades Section for Clarification on System Upgrades

    The 1lb Skylight closed loop hydrocarbon extraction system performs botanical extraction within a sealed, vacuumed system. What sets the skylight apart from the standard 1lb is the kettle top featuring a 3″ sight glass to view inside the collection vessel. Utilizing a top-fill input, solvent washes thru the material column, collecting oils as it passes over 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. https://www.bestvaluevacs.com/clasu-k-trs21.html

Optional Upgrades:
IF YOU SELECT HIGH PRESSURE CLAMP UPGRADE, you must also select the high pressure option with the other applicable upgrades to receive a system fully outfit with high pressure clamps. Upgrades come standard with single pin clamps.
• System Valves: Upgrades our Standard valves to High Quality USA Made SSP Instrumental or Swagelok fully encapsulated mini ball valves
• Base: Choose from our various collection bases. Standard base is a 6×12 welded bottom. The splatter platter replaces the 6×6 welded base with a 6” splatter and 6”x6” open spool. The 3″ sight glass base with platter adds a 3″ polycarbonate sight glass to the open spool
. • Recovery Tank: This upgrade changes the standard #30 LP tank with either: #30 Stainless Steel LP or a #25 Jacketed Stainless Steel Tank w/ Internal Condensing Coils.
• Dewaxing Column: This upgrade replaces the standard 3”x24” spools with their sleeved counterpart. The sleeve is packed with dry ice to freeze the material, stopping the waxes and lipids from being extracted.
• Ball Valve: Adds a 1.5″ inline ball valve, clamp and gasket. This is HIGHLY recommended to be paired with dewaxing columns
• Inline Sight Glass: Adds a 1.5″ Inline Pipe sight glass. This is used to see solvent drop from the material column into the collection base.
• High Pressure Clamps: Replaces standard clamps with the high pressure variants. **Note**This upgrade only applies to clamps on base unit. If other upgrades are selected, you must selected the high pressure option for that upgrade • Quick Disconnects: Replaces JIC fittings with a quick release option by either SSP or Parker.
• Active Upgrade Kits: Adds your choice of Active Recovery Kit https://www.bestvaluevacs.com/trs21-active-closed-loop-recovery-kit.html, which is used to speed up the recovery process, or the Active Recirculation/Recovery Kit https://www.bestvaluevacs.com/clasu-k-trs21.html, which allows you to recirculate solvent back thru the material column, then also speeds up recovery.
