No. 1031 is a 650ºF (343ºC), electrically-heated walk-in oven from Grieve, currently used for curing composite components at the customer’s facility.

Workspace dimensions of this oven measure 96” W x 96” D x 84” H. 140 kW are installed in Incoloy-sheathed tubular elements to heat the oven chamber, while a 10,000 CFM, 7-1/2 HP recirculating blower provides a combination airflow to the workload.

This Grieve walk-in oven features 7” insulated walls, top-mounted heating chamber, aluminized steel interior and exterior, plus 2” insulated floor with built-in oven truck wheel guide tracks.

All safety equipment is onboard to handle flammable solvents, including explosion-venting door hardware and a 4400 CFM powered forced exhauster. Motorized dampers are provided on the intake and exhaust for accelerated cooling.

No. 1031 controls include a digital programming temperature controller, manual reset excess temperature controller with separate contactors, 32-point digital recorder to track temperature, vacuum and pressure, recirculating blower airflow safety switch and SCR power controller. Also provided are a six-port vacuum manifold with pressure gauge, solenoid valve and vacuum transducer at each point, vacuum ballast tank with gauge and vacuum regulator and two-port compressed air manifold with gauge, solenoid valve and transducer.
