Lindberg/MPH announced the shipment of two car-bottom furnaces to be used for curing aircraft engine hardware consisting of ceramic-metallic composite shapes. Both furnaces can heat a maximum 5,000-pound load. One unit heats from 200°F to a maximum temperature of 2100°F, and the second unit heats to 2800°F. The electrically powered furnaces utilize two heating systems: an auxiliary preheater and an air recirculation system to achieve uniform temperature at low temperatures and radiant heating elements for uniform high-temperature operation.

The workloads are manually placed on a self-driven car and driven into the furnaces. The recirculating blower pulls air from the preheater, recirculates it through the furnace and then back through the preheater again. A butterfly valve allows the preheater air piping to be bypassed and cool ambient room air to be pushed into the furnace chamber for fast cooling. Roof-mounted exhaust flues with air cylinder-operated coves open during the low-temperature curing process to vent fumes from the product.
