Wisconsin Oven has designed a gas-fired belt conveyor oven to cure powder paint on aluminum water bottles with a production rate of 1,500 bottles per hour.
The oven chamber is 3 ft × 12 ft × 10 inches high and has a maximum temperature rating is 500°F with a normal operating temperature of 125°F. It uses a 1 × 1-inch flat wire belt made of 304 stainless steel, and has a digital conveyor speed display and variable-frequency AC drive with electronic torque limiting, adjustable from 0.5-1.0 fpm.
The UL labeled and certified NEMA 12-control enclosure includes IEC style motor starters, push buttons and pilot lights. The temperature is controlled by a Honeywell UDC2500 temperature controller. The recirculation system uses adjustable louvers, direct-drive blowers and a bottom-up airflow design for optimum air flow efficiencies.
The oven also has an E-Pack upgrade that includes thicker wall panels, more efficient motors, a door-limit switch and other energy-saving items to reduce operating costs, the company says.
