Thermal Product Solutions shipped seven glassware drying ovens to a university based in the Midwest. The Gruenberg ovens have a maximum temperature rating of 650°F and utilize a vertical-up airflow, which maximizes heating rates and temperature uniformity of the product load.

Each oven contains a circulation fan located in a conditioning plenum chamber on the top of the oven. This fan directs air through a diffuser panel on bottom of the chamber and flows vertically up through the product. The air exits the work chamber on the top of the chamber back to the heaters for reheating and recirculation.
