Combined with a reference thermocouple that maintains contact with the shelves, Cascade Botanical ovens provide even, stable temperatures throughout the entire oven, making every inch of shelf space usable.

Uniform Heating – Evenly spaced heaters on both the oven sides and bottom of the oven, combined with solid aluminum shelves, maximizes heat distribution.

Safety Certified – Cascade Botanical vacuum ovens are the first in the industry to carry a safety certification from a Nationally Recognized Testing Laboratory (NRTL) on the entire line of ovens at no additional cost to the customer.

Quarter-Turn Swagelock Valves – Vent and vacuum valves go from fully open to fully closed in just a quarter turn and allow precision micro-adjustments.

Digital Vacuum Gauge – A digital vacuum gauge is now standard on all models.

Solid Construction – All Cascade Botanical ovens are built with the highest-quality materials and assembled by hand with pride in Oregon. Tired of replacing your ovens every few months? Give us a call and level up!

Recommended Pumps

Choosing the right pump for botanical extraction is extremely important. The key is to find something powerful enough to remove moisture and solvents without removing terpenes and other essentials. To learn more, visit our pumps page and blog.

Cascade Botanical sells everything you need for a complete solvent vacuum extraction. We accept cash, money order, check or credit card.


Oven temperature is controlled via a Watlow programmable ramp and soak controller. (Ask about how it can be configured to automatically execute your vacuum drying process). The TVO-2 also includes a fully independent digital overtemp protection controller. Vacuum is read in inches of Mercury (Hg) via a bourdon tube. Vacuum and purge hand valves are conveniently located on the front control panel. The purge valve is set up to allow for backfilling with N2. Rear Vacuum connections include: a 3/8″ connection for the vacuum pump & 1/4″ connection for purge / backfill. An additional KF25 vacuum connection is located in the rear center for feedthru or sensor connections. The TVO-2 also has 3 stackable aluminum shelves. Cascade TEK offers the appropriately sized connection kits and pumps to bring the entire system on line.

Cascade TEK can automate the TVO-2 to execute your vacuum drying process with the push of a button. This includes automatic opening/closing of vacuum/vent valves, automatic backfill sequence and temperature ramps, alarms and shut down.
