Lewco Inc. delivered a continuous process oven to a manufacturer of welded wire-mesh fabrics. The oven is rated for a maximum operating temperature of 1000°F and will be used to cure PVC-coated, welded wire mesh at temperatures of 900-950°F. The oven features a single, direct-fired, natural gas heater box with a capacity of 2,000,000 BTU/hour and is equipped with a recuperative burner. A remote heat exchanger preheats combustion air, which reduces fuel consumption while decreasing heat-up time.
The oven is equipped with a 15,000-CFM circulation fan and a 1,500-CFM exhaust fan. The high-efficiency circulation fan and integral plenums deliver uniform “dual vertical” airflow throughout the oven workspace. Oven controls include a single setpoint process temperature controller with a redundant high-limit controller to provide precise temperature control and over-temperature protection.
PVC-coated wire mesh can be used for marine traps, fencing and shelving.
