The Grieve Corporation provided a 1,250°F (667°C) inert atmosphere oven for a customer using it for heat treating firearms components at its facility. Workspace dimensions of this oven measure 48” W x 48” D x 36” H. 30 KW are installed in Incoloy sheathed tubular heating elements, while a 1,400 CFM, 1-1/2 HP recirculating blower provides horizontal airflow to the workload. Inert atmosphere ovens protect parts from oxidation using any non-flammable gas such as nitrogen, argon, or carbon dioxide.
This Grieve inert atmosphere oven features 12” insulated walls, all interior seams welded gas-tight, an air jacket on the inner oven for cooling, 16” high integral oven stand, 16-gauge 304 stainless steel interior and enamel-painted aluminized steel exterior. The oven is reinforced for 2,000-pound loads, allowing the customer’s part rack to sit on the oven work space floor.
The oven meets all requirements for inert atmosphere construction, including those in NFPA 86, FM, and OSHA standards.
Controls on this Grieve oven include a programmable temperature controller with data logging capability, 975 CFM cooling blower with air flow safety switch, and automatic purge solenoid. An inert atmosphere inlet (1/2” NPT) with pressure regulator maintains positive pressure within the oven.
