A company in the defense industry will use an explosion-resistant, friction-heated cabinet oven to dry molding powders. The Gruenberg oven, shipped by Thermal Product Solutions, has an operating temperature of 149°F (65°C).

The oven has 4” thick, mineral-wool-insulated walls to minimize heat loss. The construction of the chamber uses a structural steel frame with interconnecting struts that are non-continuous from inner to outer walls to keep the exterior cool. The interior of the oven is designed to be intrinsically safe with spark-resistant blowers, which minimizes the risk of any ignition sources.
