Enhanced-duty batch oven is supplied with a rear-mounted heater-box and heat capacity of 700,000 BTU/hr. A 12,000-cfm high efficiency circulation fan delivers uniform dual airflow throughout the workspace. Due to the NFPA Class A rated requirement, a 1125-cfm exhaust fan is included. Many features are involved in meeting this standard, including safety ventilation, a purge cycle, and explosion relief. Bi-parting swing doors with a three-point cam-style latch provide a positive seal during heating. A zero-speed switch is included on both the circulation and exhaust fan for air-proving circuit.
