Large-capacity 500ºF Electric Walk-in Oven

No. 857 is an electrically-heated 500°F (~260°C) walk-in oven from Grieve, currently used for annealing plastics at the customer’s facility. Workspace dimensions are 7’ wide x 12’ deep x 7’ high.  100 KW are installed in Incoloy-sheathed tubular heating elements to heat the oven chamber, while a 17,500 CFM, 15 HP recirculating blower provides horizontal airflow to the workload.

The oven has 4” thick insulated walls, plus an aluminized steel interior and exterior.  The door sill on this unit was eliminated and both oven doors are equipped with drag seals.  Wear bars were also installed on the sides of the workspace for added durability.

Controls onboard No. 857 include a 975 CFM powered forced exhauster and motorized dampers on the intake and exhaust for accelerated cooling of the oven chamber.
