A 350F gas-heated tunnel oven from Grieve is being used for drying water from aluminium parts hung on a monorail pass-through conveyor at a customer's facility.

Workspace dimensions of this unit measure 30"Wx192"Dx66"H.

The workload passes through a 24" long insulated, unheated entrance vestibule, a 144" long insulated heat zone with recirculated airflow and a 24" long insulated, unheated exit vestibule.

This oven is suspended from the factory ceiling and operated by a remote control panel.

500,000 BTU/HR installed in a modulating natural gas burner heat the workspace, while a 6000 CFM, 5-HP recirculating blower provide vertical downward airflow to the workload.

The unit has a bottom-mounted heat chamber and a 24"Wx72"H side door for access to the chamber and workspace.

This tunnel oven features an aluminized steel interior and exterior.

Interior supports are provided for the customer's pass-through monorail.

4" thick insulated walls are also included.

All safety equipment required by IRI, FM and NFPA Standard 86 for gas-heated equipment are onboard this Grieve oven, including a 650 CFM forced exhauster.
