Lewco Inc., Sandusky, Ohio, delivered a 500°F (260°C) enhanced-duty walk-in oven that will be used to dry various parts during a manufacturing process.
The electric oven is equipped with a 26,000-cfm high efficiency circulation fan that delivers horizontal airflow and provides uniform heat throughout the workspace. A 500-cfm exhaust fan aids in the drying of the parts, but it also was required per NFPA 86, Class A due to solvents being present in the workspace.
Controls include a Watlow F4T temperature controller and redundant high limit controller. Control functions include the ability to create, edit and save multiple recipes; control oven operations; check oven status; and monitor, record and retrieve process data. A humidity sensor controls the fan speed as the parts dry.
