Two-zone, Dual Belt Conveyor Oven from Grieve

No. 1022 is a 550ºF, electrically-heated, two-zone, dual belt conveyor oven from Grieve, currently used for encapsulation curing of large electrical coils in fixtures at the customer’s facility.  Workspace dimensions of this oven measure 8’ W x 40’ D x 18” H.   480KW (240KW per zone) are installed in Incoloy-sheathed tubular elements to heat the oven chambers, while two 20-HP recirculating blowers provide a 49,000 CFM vertical downward airflow to the workload.

This Grieve conveyor oven comprises a 2’ long open belt loading zone and 3’ long insulated, unheated entrance vestibule, two 20’ long insulated heat zones with independent recirculated airflow and temperature control, 3’ long insulated unheated exit vestibule and finally a 2’ long open unloading zone for the workpieces.

No. 1022 has 6” insulated walls throughout, aluminized steel interior/exterior and is split into two sections for shipping.  Side doors along the length of the oven permit access to the workload and heating chambers. This Grieve conveyor oven is built with all safety equipment required for handling flammable solvents and is constructed to NFPA 79/NEMA 12 electrical standards.

The oven further features two 3’ wide, 1-3/16” diameter cross bar conveyor belts with 1-HP motor drive, variable from 0.5 to 9 ipm.   The conveyor belt drive is used in either index or continuous mode.  Removable drip pans are provided below the conveyor assembly.

Controls on the oven include separate power and control panels, plus photo eyes at the unload station to signal an alarm, if the workpiece unloading is not cleared before conveyor indexing, SCR power controller for each zone and a tower light to indicate oven status.   All control functions are accessed through a touch screen HMI connected to the onboard PLC.
