Product Description

The TVO-2-2 vacuum oven has a capacity of 1.7 cubic feet and is our most popular benchtop vacuum oven model. Cascade TEK is happy to offer everything you need for a complete vacuum drying system – including dry or wet vacuum pumps, connection kits and a variety of door gasket materials suitable to your application.

Important Vacuum Oven Features

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-2-2 also includes a fully integrated digital overtemperature protection controller. Vacuum is read in inches of Mercury (Hg) via a digital vacuum gauge. Vacuum & Backfill hand valves are conveniently located on the front control panel. The purge valve is set up to allow for backfilling with any inert gas. Rear connections include: a 3/8″ tube stub for the vacuum pump & 1/4″ tube stub for backfill. An additional KF25 vacuum connection is located in the rear center for optional feedthrough or sensor connections. The TVO-2-2 also has 3 stackable aluminum shelves. Cascade TEK offers the appropriately sized connection kits and pumps to bring the entire system on line.

Myself and the rest of the team have been very pleased with the TVO-2. Specifically, the ease of use (e.g. recipe creation, ease of adding additional outputs, inputs, etc.), and the general equipment reliability thus far. We use the system ~16 hrs / day nearly non-stop and the only maintenance required has been gasket replacement, which is an expected event.
