A manufacturer of plumbing systems will use a conveyor oven rated for a maximum operating temperature of 500°F (260°C) to dry cast iron cores at 400°F (205°C).
The oven, which was designed and supplied by Lewco Inc., includes a single, direct-fired, natural-gas heater box with a capacity of 700,000 BTU/hr. A 7,000-cfm circulation fan and integral plenums deliver uniform vertical-down airflow throughout the oven workspace. The oven also is supplied with two insulated bolt-on access panels to ease entry to the oven chamber for service and maintenance.
Oven controls include a programmable logic controller (PLC) and touchscreen HMI, which incorporates temperature, safety and motion abilities into a single operator interface.
