Bulletin CA-470
Inert atmosphere ovens for operation at up to 4000C. Protect parts from oxidation using any non-flammable gas such as Nitrogen, Argon or Carbon Dioxide. Front to back horizontal airflow completely surrounds work on shelves or large parts placed directly on the optional reinforced workspace bottom. Includes cooling jacket, which can be equipped with optional cooling atmosphere purge solenoid, cooling blower and programming temperature controller provides completely automatic sequencing.

Each features completely wired, top access control panel enclosing terminals for incoming power, temperature controllers, push buttons and pilot lights. Motor starter and heating element contractors electrically interlocked to shut off heaters if power is interrupted and to permit operation of blower without heat of cooling. Incoloy sheathed tubular heating elements
Two (2) reinforced 100 lbs. uniformly distributed load capacity, nickel-plated wire shelves. 304 stainless steel interior and Trilite Green enamel painted aluminized steel exterior.
Inert atmosphere is introduced at blower shaft (½" NPT) and positive oven pressure maintained by inlet pressure regulator. Atmosphere flow indicated on 0-100 CFH flow meter. Oven pressure indicated on 0-2" water column pressure gauge. Continuously welded inner oven construction with compression fittings at wall penetrations maintains atmosphere integrity. Atmosphere outlet equipped with pressure relief, which can be manually opened to increase inert gas flow for initial purge of air from oven. Adjustable positive latching door hardware and offset hinges assures positive door seal
