Exceptional Temperature Control & Stability

The Cascade TVO-5 uses a unique control logic not found in most lab grade vacuum ovens. The temperature probe is INSIDE the oven, which minimizes temperature overshoot and delivers best-in-class temperature stability and uniformity particularly in the low temperature ranges. Accurate, stable temps throughout the TVO-5 eliminate hot and cold spots, making accurate use of every inch of shelf space.

Touchscreen LED Smart Controller

The TVO-5 controller is a flat panel touch screen with built-in, controls that minimze temperature overshoot. When the oven door is open, the controller will wait and not agressively call for heat to attempt to keep the oven interior stable. When the oven is being vented, the controller will pause as to not over-react and overshoot temperature during this temporary event.

  • Read Temperature in degrees Celcius or Fahrenheit
  • Read Vacuum in Torr or Inches of Mercury

Energize Vacuum Pump From Oven Control Panel

Turn the vacuum pump off and on from the oven control panel. No more reaching around, behind, beside to turn the vacuum pump off an on. Vacuum pump plugs directly into the back of the oven's auxillary outlet.

Independent Overtemp Failsafe Protection

The Cascade Sciences TVO-5 is equipped with a heating cutoff system that will automatically stop power to the heaters when the oven shelf temps exceed 392°F or 200°C. This protection system will provide peace of mind for overnight processing or unattended vacuum bake outs.

Log Temperature & Vacuum With Data Port

The TVO-5 features a rear mounted data port which outputs a digital log line once per minute. Viewing/logging this data requires terminal emulator software such as the open source (BSD License) emulator Tera Term.

NRTL Certification #U8 170464972 077. No Extra cost.

The TVO-5 Vacuum Oven comes certified by the Nationally Recognized Test Lab, TUV. This certification is a requirement by many municipalities and is often an extra charge on low cost ovens.

Equipped for Inert Gas Backfill. Built-In Safety Relief

Introduce inert gasses such as nitrogen, argon, helium, etc. as part of your process via the 1/4"" rear vent barb. The maximum backfill pressure is 15PSI. In an overpressure situation, a simple, built-in safety relief allows gasses to escape via a spring loaded tempered window.

Flexible Pumping / Feedthru Connection Ports

The TVO-5 ovens offer two different vacuum oven connection points. The standard connection is a 3/8th dia barb located at the rear of the oven. It is connected to the vacuum valve level on the front control panel. For even faster evaporation, purging or drying consider upgrading to the MAX EVAP connection kit. The MAX EVAP connection kit secures to the oven's rear 1"" dia KF-25 port located on the back center of the chamber. The MAX EVAP connection never reduces flow by continuing with 1"" diameter vacuum rated clear lines, a 1"" dia KF-25 side mounted vacuum valve and KF-25 fittings and hardware. This KF-25 port can also be used to run temperature feedthrus, or monitoring sensors inside the vacuum chamber during processing.

Ergonomically Designed, Easy Quarter-Turn Valves

For anyone that has struggled with consistently turning the small, round, low-quality vacuum/vent valves, relief is in sight. You will love our large, quarter-turn vacuum/vent valves. Your wrists will thank you!

ANSI Rated Tempered Glass + USA Made Steel

Cascade ovens are made in Oregon, USA with high quality materials. Our glass is NGI-USA Tempered and certified to ANSI Z97.1.2007 16CFR / 201 11. Our door handles are rugged brushed steel, not plastic. Our vacuum vessels are constructed with American made steel. We've tried lower cost, imported steel. But over time, vacuum chambers made of lesser quality/lower tolerance material cannot withstand the flex and pressure changes of vacuum pumping/venting/purging. This can deteriorate vacuum integrity and the oven will lose its ability to hold vacuum.
