500ºF Electric Walk-in Oven

No. 973 is an electrically-heated, 500ºF (260ºC) walk-in oven from Grieve, currently used to cure rubber parts in rotating baskets at the customer’s facility.  Workspace dimensions measure 36” W x 60” D x 60” H.  40KW are installed in Incoloy sheathed tubular elements to heat the unit, while a 4200 CFM, 3 HP recirculating blower motor provides combination horizontal/vertical airflow to the workload.

A motorized roller rack is onboard with two levels of 4” dia. driven rollers, each supported by metallized carbon bearings.  Each level of rollers holds two 20” dia. stainless steel perforated drums, rotating at 6 RPM, which carry the workload.  The rollers are driven via sprockets and a roller chain, exterior to the oven rear, by a 3/4 HP AC motor with inverter variable speed control, gear reducer and torque limiter.

This Grieve walk-in oven features 4” thick insulated walls throughout and an aluminized steel interior and exterior.  There’s also a top-mounted heat chamber, single front door and an access door to allow cleaning of the heaters.

Controls on No. 973 include a 10” dia. circular chart recording and programming temperature controller, manual reset excess temperature controller with separate contactors and recirculating blower airflow safety switch.
