No. 969 is an electrically heated 200ºC (392ºF) laboratory oven from Grieve, currently used for preheating 15 lb. molds at the customer’s facility.  Workspace dimensions of this oven measure 12”W x 10”D x 10”H.  800W are installed in Incoloy-sheathed tubular elements to heat the unit, while gravity convection provides the airflow to the load. 

This specially modified Grieve lab oven features include: 1” insulated walls throughout; aluminized steel interior; stainless steel exterior with #4 brushed finish; heavy duty door latch; reinforced door hinge; shelf supports bolted through the oven walls to support the load at a double shelf height; and an adjustable fresh air inlet damper at the oven bottom to control the amount of fresh air entering the chamber. 

An added feature for accuracy, the temperature control shaft onboard No. 969 is recessed and slotted to avoid a set point change.
