Workspace dimensions measure 72″ wide x 156″ deep x 96″ high. 360 kW installed in Incoloy sheathed tubular heating elements provide the power, while a 24,500 CFM, 20 HP recirculating blower provides a vertical downward airflow to the workload.
This Grieve oven features 8″ insulated walls, Type 304L, 2B finish stainless steel interior, stainless steel exterior with #4 brushed finish, removable top mounted heat chamber, and 6″ insulated floor with truck wheel guide tracks for easy loading and unloading.
No. 946 has double doors, front and rear, each with inner and outer door gaskets. The inner gasket seals against the door plug, while the outer gasket seals directly against the front of the oven.
Safety equipment is onboard for handling flammable solvents, including explosion-venting door hardware.
