CVO-5-EX Flammable Solvent Vacuum Oven

$21,997.00

Cascade Sciences by Agrify CVO-5-EX vacuum ovens are certified for safe operation in locations where explosive concentrations of specific volatile gases or vapors occur infrequently, unintentionally, and only for short durations — typically due to accidents, leaks, or failure of a positive ventilation system.

NFPA 70: The UL 60079-2 hazardous equipment certification also satisfies the US National Electrical Code’s NFPA 70 Article 500 and 505 requirements for hazardous (classified) location equipment as well as NFPA 496 requirements for purge and pressurized equipment.

The Cascade by Agrify Difference


Vacuum ovens have been around for decades. Basic vacuum ovens are mass-produced and sold by many large laboratory equipment distributors. But there are key differences between Cascade and other less costly, often imported vacuum ovens:

Touchscreen Smart Controller

The CVO-5 controller is a flat panel touch screen with controls that minimize temperature overshoot. When the oven door is open, the controller will wait and not aggressively 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 Celsius or Fahrenheit
  • Read Vacuum in Torr, Bar or Inches of Mercury

Independent Overtemp Failsafe Protection

The Cascade Sciences CVO-5-EX is equipped with a heating cutoff system that will automatically divert power to the heaters in the event of an over-temperature event. It must be set prior to running a baking application and set well below the auto-ignition temperature of the solvent being used.

Equipped for Inert Gas Backfill.

Introduce inert gasses such as nitrogen, argon, helium, etc. as part of your process via the ¼” rear vent barb.

Flexible Pumping / Feedthru Connection Ports

The CVO-5 series 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 optional MAXEVAP connection kit. The MAXEVAP connection kit secures to the oven’s rear 1” dia KF-25 port located on the back center of the chamber and can be installed anytime. The MAXEVAP 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 in safe environments.

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.

Rigorous Quality Assurance in an ISO Certified, USA Manufacturing Facility

Cascade Sciences manufactures our ovens in Oregon, USA. We are proud of our ISO 9001 Certification/Accreditation. Each oven completes a series of quality assurance procedures before shipment.
