SPX

Blue M SPX ovens operate using mechanical forced-air convection. Airflow is generated by a direct-drive motor with a multi-blade centrifugal fan and is directed by baffles to ensure uniform thermal distribution across the chamber volume. The oven can be used under constant positive pressure and includes a gas purge and gas holding charge feature. An inert gas purge system eliminates moisture and vents contaminants; an adjustable inert gas flowmeter is provided. The gas delivery system introduces gas through the agitation fan shaft to ensure proper mixing and prevent air from being drawn into the chamber. The fan impeller is stainless steel to minimize contamination and maintain positive chamber pressure. A cooling facility with a stainless steel cooling coil speeds cooldown and allows near-ambient operation.^[2][3]

Blue M SPX ovens are used in a variety of thermal processes that require inert or oxygen-reduced environments. Application areas include curing polyamide coatings, moisture drying, baking photoresist coatings, and various pharmaceutical and electronic processes. In semiconductor manufacturing, these ovens are employed for drying lithium-ion battery electrodes under nitrogen to prevent oxidation, thermal curing of epoxy composites, and precursor annealing. The ovens also serve in materials science research, catalyst activation, and pharmaceutical stability testing.^[2][3]
