Two custom paint-baking ovens will be used to cure a powder coating, dry paint and preheat automotive components, including complete bodies and frames. Lewco, Sandusky, Ohio, won the contract to design and build the ovens for an automotive manufacturer’s research facility.
The customer’s application required bi-parting swing doors at each end to permit pass-through processing. To reduce the ovens’ impact on the surrounding area, exhaust hoods were installed above each set of doors. Fans over the hoods automatically start to remove any fumes and heat that exit the workspace when the doors are opened.
Both ovens are heated with direct-fired natural gas and have a maximum operating temperature of 500°F (260°C). Each oven is equipped with two 50,000-cfm circulating fans to deliver dual airflow throughout the workspace. Due to the NFPA Class A rated requirement, a 3,000-cfm exhaust fan is included to remove volatiles. Recirculation air filters were provided to maintain a class A finish on the parts.
