This is HOT!

Now that I have your attention, I thought I’d share some tips about Forced Air Oven versus Gravity Convection Ovens. 

If you are still reading, there are many different types of industrial or commercial drying methods out there.  Convection, Gravity Convection, Forced-Air, etc…  Some of the terms I find to be misleading.  And there’s a reason for price difference between the different types of drying ovens.  

In A Nutshell:   

  • Convection Ovens have a fan of some sort to move hot air around inside the oven.  Results in faster, more uniform drying of material. More expensive (and it just happens to be what Cascade TEK sells).
  • Gravity Convection is a term I see used that I find misleading.  Gravity means no fan.  Heat rises and that’s what reckless marketers mean by “convection”.   Slower drying times.  Stable, but heat rises, so watch for “hot spots.”  Very affordable.

I’ve put together an easy-read, detailed explanation of How Forced Air Ovens Work.  Check out this pdf, and if you have any questions drop me a line at
