Its workspace dimensions measure 38 × 50 × 38 inches, and it features 40 kW installed in Incoloy-sheathed tubular elements to heat the oven chamber, while a 2,000-cfm, 2-hp recirculating blower provides horizontal airflow to the workload.

The oven features 6-inch insulated walls, an aluminized steel exterior, an Inconel 600 interior with continuously backwelded seams and special exterior paint. It also features full inert-atmosphere construction, including pressure regulator, flow meter, pressure gauge, internal high-temperature gasket, all-welded expansion connection in the doorway throat, air jacket on the inner oven for cooling, ½-inch-thick cellular silicone rubber atmosphere seal, blower shaft seal, positive latching door hardware, adjustable offset door hinges, outlet with pressure relief, interior seams welded gas-tight, and all wall penetrations fitted with compression fittings.

A hinged door jacket with 4-inch-diameter connector enables the jacket to be ventilated. Oven controls include a programming temperature controller, manual reset excess temperature controller, SCR power controller and fused disconnect switch.
