Six inert gas cabinet ovens designed for the medical industry incorporate a cabinet oven design and allow for low PPM oxygen levels. The Blue M unitized ovens have a maximum temperature rating of 1100°F (593°C). The inert-gas ovens were constructed from a structural steel frame that supports the 304 stainless steel chamber liner and the exterior cold-rolled steel sheet metal. All interconnecting struts are noncontinuous, which keeps the exteriors cool. They utilize horizontal airflow, which maximizes heating rates and temperature uniformity of the product load. A circulation blower in a conditioning plenum chamber on the bottom of the oven directs air through a diffuser panel to flow horizontally across the product. The air exits the work chamber on the opposite side duct wall back to the heaters for reheating and recirculation.
