Inert atmosphere construction on this oven includes pressure gauge, internal high-temperature gasket, all-welded construction in the doorway throat, air jacket on inner oven for cooling, says the company. Controls on No. 966 include a digital programming temperature controller, manual reset excess temperature controller with separate contactors and recirculating blower airflow safety switch.
