A Class B oven with a maximum temperature rating of 250°F (121°C) will process up to 5 gal of water per batch from 1,500 lb of metal powder. Thermal Product Solutions (TPS) shipped the Gruenberg cabinet oven to a company involved in research and development.

The drying oven has one circulation blower direct drive in a conditioning plenum chamber in the top of the oven. This blower directs air through a diffusor panel on one side of the work chamber and flows horizontally across the product. The air exits the work chamber on the opposite wall back to the heaters for reheating and recirculation.
