Grieve Corporation introduces the No. 810, a 500°F gas-heated, two-zone belt conveyor oven, which is well-suited for aluminum pistons. Workspace dimensions inside this unit measure 42" wide × 24' deep × 15" high.
The workloads travel atop a 36" wide, 1" × 1" high-carbon steel flat-wire conveyor belt with ¼ hp motor drive, variable from 0.8" to 15" per minute, through an 18" long open loading zone; 36" long insulated heat zone with 2 hp, 2,000 CFM recirculated airflow; 16" long insulated, unheated vestibule; 16' long insulated heat zone with 10 hp, 12,500 CFM recirculated airflow; 12" long open zone; 36" long cooling zone and an 18" long open unloading zone.
350,000 BTU/HR are installed in modulating natural gas burners in each of the two heating zones on the conveyor oven. An aluminized steel exterior houses 4" insulated walls, Type 304 stainless steel interior with continuously welded seams in zone one and aluminized steel interior in zone two.
A 16" diameter tubeaxial fan driven by a ¾ hp motor pulls room air through the cooling zone.
All safety equipment required for gas heated equipment by IRI, FM and NFPA Standard 86 is on No. 810, including 325 CFM, ⅓ hp powered forced exhausters, airflow safety switches, hi/lo gas pressure switches, excess temperature controllers and electronic flame safeguard protection.
This unit also features doors at both ends of the workspace to contain heat, as well as pushbutton electric ignition for ease of operation and a recording thermometer.
