April 26, 2013—Grieve Corporation introduces No. 815, a 500°F electric rotary hearth oven, currently in use for preheating gears at a customer’s facility. Workspace dimensions inside this unit measure 76” wide x 76” deep x 24” high.  A 72” diameter rotary hearth is constructed from angle rings with 90 1-3/8” wide x 7-3/8” long x 3-5/8” high slots to hold the workpieces on edge while processing. The hearth is driven by a 1/4 HP motor through a gear reducer with torque limiting device.  The hearth indexes one position each time the loading door is opened and closed. Two 2000 CFM, 2 HP recirculating blowers provide a vertical downward airflow over the workload.  Special safety equipment for handling flammable solvents is featured on this Grieve rotary hearth oven, including a manual reset excess temperature controller, separate heating element control contactors, a 325 CFM powered exhauster, and a purge timer. No. 815 features an aluminized steel interior and exterior, plus 4” insulated oven walls. The unit was entirely designed, engineered, built and full tested by Grieve.
