North American High Velocity Family

 

Bulletin 4485

page 9

If the 4485 do es not suit your application, the original North 
American Tempest® and HiRAM® high velocity burners off er 
many features the 4485 SE type burners do es not. North 
American is still developing new models, and enhancements to 
our classic burners.

 

4441 TEMPEST

®

 

The 4441 Tempest® is the improved version of the innovative 
4442, the original high velocity, high excess air, nozzle mix 
burner that revolutionized the industrial heating industry. It off ers 
many advanced features, including higher velocity, wider stable 
operating range and lower NOx options. The high fi re capacity 
range is 0.13M to 5.4M Btu/h HHV. 

4445 TEMPEST

®

 

The 4445 Tempest® is a small diameter high velocity burner that 
can be ordered to fi t in 9” to 40” thick walls. The 4445-capacity 
range is 195K to 1.5M Btu/h HHV. They can be ordered with a 
fl ame rod, or it can be omitted for UV fl ame supervision. 

4575/6575 HIRAM

®

 

The 4575/6575 HiRAM® burners are low NOx high velocity
burners available in larger sizes. 

 

Tile options include:

   

 Slotted tiles for better temperture uniformity

   

 Threaded metal tile exits, for unique mounting options

   

 Engineered tile exits to provide higher velocities than  

   

    4485 type burners

   

 Mounting plates that give the "A" style thin wall tiles  

   

    an 11" length.

   

 Light weight ceramic tiles that can be used in up to  

   

    3000°F applications

 Product
