Grieve’s No. 965 cabinet oven is electrically heated to 1,350°F and is suited for heat-treating titanium. With a workspace measuring 24" × 24" × 24", the oven is heated with 34-Kw nickel chrome wire coils. A 1,300-cfm, 1 1/2-hp alloy recirculating blower provides horizontal airflow to the workload.
The cabinet features 11" thick insulated walls and 9" of 10-lb/cf density Rockwool insulation. It is also equipped with an aluminized steel exterior, Type 304 2B finish stainless steel interior, and inner and outer door gaskets. The inner gasket seals directly against the door plug, and the outer gasket seals directly against the face of the oven.
Controls include a digital indicating temperature controller; a manual reset excess temperature controller with separate contactors; a recirculating blower airflow safety switch; a 10" diameter circular chart temperature recorder; and an SCR power controller and fused disconnect switch.
