Cascade CDO-28 Dry & Decarb Oven


Cascade CDO-28 Dry & Decarb Oven

 This item carries up to a 2 week lead time.



Cascade’s CDO-28 is purpose-built for large-scale, industrial decarboxylation of material with additional features:


  • 28 Cu. Ft.


  • Built-in Humidity Sensor assists in dryness targets


  • Stay in place sliding extension shelves


  • NRTL Certification


  • 6 each FDA & temperature rated fine micron mesh bags for ground material – Mesh bags are required to prevent oven contamination and material loss.


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 includes a built-in humidity sensor and fine micron mesh bags for drying or decarboxylating powders or ground material.


Ideal Uses:


  • Industrial scale 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



Model CDO-28 Features


  • Horizontal Airflow. The airflow moves uniformity 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



The Cascade Difference


Basic forced-air lab ovens are mass-produced and sold by many large scale laboratory equipment distributors. But there are key differences between Cascade and other less costly, often imported lab ovens:



Independent Overtemp Failsafe Protection


The Cascade Sciences CDO-28 is equipped with a heating cutoff system that will automatically stop power to the heaters when the overtemp setting is tripped. This protection system will provide peace of mind for overnight or unattended drying processing.



NRTL Certification. No Extra cost.


The CDO-28 Oven comes certified by the Nationally Recognized Test Lab, TUV. This certification is a requirement by many municipalities.
