Grieve’s No. 987 is an 850°F electric cabinet oven currently used for baking paint samples. With workspace dimensions measuring 20 × 20 × 20 inches, the oven features 10 kW installed in Incoloy-sheathed tubular elements to heat the oven chamber, while a 600-cfm, 1/2-hp recirculating blower provides horizontal airflow to the workload.

The No. 987 oven also features 4-inch insulated walls, aluminized steel exterior, Type 304 2B stainless steel interior, a silhouette plate with removable cover inside the door opening and an oven hearth driven by a 1/4-hp motor through a gear reducer with a torque limiting device variable from 1 to 27 rpm. The 19-inch-diameter oven hearth is constructed from Type 304 stainless steel with 1-inch studs on 1-inch centers to support the paint coupons in process.

All safety equipment required for handling flammable solvents are onboard No. 987, including explosion-venting door hardware. Controls include a digital-indicating, time-proportioning temperature controller and excess temperature controller with separate heating element control contactors. An automatic door switch stops hearth movement when the oven door is opened.
