FEATURES
RUGGED, VERSATILE, AND RELIABLE: An ultra stable burner designed to operate with 20% excess air in chambers at temperatures up to 2000°F and under negative or slightly positive pressures. Cold, tight chambers present no problem for this rugged, low- maintenance workhorse. Proven reliability while operating with natural gas, any grade of commercial fuel oil, crude oil, pitch, or refinery bottoms. LOW NOx: By their design the package burners are inherently Low Nox. In conjunction with other NOx reducing features, they are capable of meeting emission limitations for new or retrofit applications in environmentally sensitive installations. However, emission levels will vary from one application to another. Contact your North American for your specific application.
BUILT-IN FAN: Delivers 100% of combustion air required for burner operation. Eliminates need to install an expensive and bulky air delivery system. Avoids dependency of several burners on one blower. CONTROL VARIETY: Building from the basic burner package, two ratio control systems are available along with many pre-packaged gas and oil trains, motorized controls, flame safeguard accessories, and programming systems. WIDE RANGE OF CAPACITIES: 3 000 000 to 30 000 000 Btu/hr, in seven sizes. Typical air turndown is 4:1 on standard models. Greater turndowns are available for special applications.
