The oven, designed and manufactured by Lewco Inc., Sandusky, Ohio, includes a single, direct-fired natural gas heater box with a capacity of 1 million BTU/hr. The custom oven is equipped with a 10,000-cfm circulation fan and a 750-cfm exhaust fan that include air-proving circuits that are electrically interlocked with the heating circuit. The circulation fan and integral plenums deliver vertical down airflow equally throughout the oven workspace.
Due to the unique shapes of the parts to be cured, the oven is equipped with a dual-lane conveyor that includes a 6" wide tabletop chain with customer-provided stanchions and fixtures bolted to the chain. This allowed the customer to double the number of parts passing through the oven. An expanded metal guard is included around the entrance and exit end of the oven to protect operators from touching hot parts exiting the oven.
