Cascade CDO-28 Dry & Decarb Oven



This powerful, large capacity forced air laboratory oven uses heated air to remove unwanted compounds from products that are not temperature sensitive.

Our ovens feature horizontal airflow that enables more consistent distribution of air. They are designed to have uniform temperatures and airflow across the shelf space from right to left.

The CDO-28 has a 28 cubic foot capacity includes a built-in humidity sensor and fine micron mesh bags for drying or decarboxylating powders or ground material.


Model CDO-28

  • Purpose-built for large-scale, industrial decarboxylation of material with additional features
  • Industrial scale (28 Cu. Ft.) forced-air convection drying below 149ºC / 300ºF
  • Decarboxylation processes
  • Drying organic material. Drier material will yield better results than processing wet material. Removing as much moisture as possible pre-processing will save time in the post process of vacuum purge and winterization.
  • Lab glassware dryer
  • 6 each FDA & temperature rated fine micron mesh bags for ground material – Mesh bags are required to prevent oven contamination and material loss.



  • Horizontal Airflow. The airflow moves uniformly across the shelf space from right to left
  • Digital set-point control, timer and overtemp failsafe protection
  • Humidity sensor displays relative humidity levels during process
  • Includes 6 sliding, extend and stay in place shelves for ease of loading.  Stainless Steel.
  • Includes 6 temp-rated, fine micron mesh bags for easy loading & uniform drying of messy powders, ground up or turbulent materials
  • Fast heat-up: 24 Minutes to 149ºC (300°F) / Uniformity: +/- 2ºC (3.5°F)
  • Stainless steel interior / Food lab grade construction. 301 SST Shelves
  • Triple wall construction meets CE, UL and TUV requirements to keep work-spaces cool.
  • Quality Made in Oregon USA
  • 1 Year Warranty
