A specialty chemicals company will use a Blue M convection oven to dry precious metals and granules at 150°F (66°C). The metal powder will be placed on customer trays and then placed on oven shelves during the drying process.
The industrial oven, manufactured by Thermal Product Solutions (TPS), White Deer, Pa., has a maximum temperature rating of 300°F (149C). A special Halar coating was applied to the oven interior to help protect the work space against off-gassing HCL during the drying process. The HCL would damage the standard stainless steel interior, so the oven liner, duct walls, ceiling and floor were all coated with the Halar coating. Halar-coated shelves were also provided.
