Inert Atmosphere Ovens

These ovens protect parts from oxidation using any non-flammable gas such as Nitrogen, Argon or Carbon Dioxide. Horizontal air flow completely surrounds work on shelves or large parts placed directly on the optional reinforced work space bottom. Includes cooling jacket which can be equipped with optional cooling blower and automatic dampers. Installation of optional atmosphere purge solenoid, cooling blower and programming temperature controller provides completely automatic sequencing.
