North American High Velocity Family
If the 4485 does not suit your application, the original North American Tempest® and HiRAM® high velocity burners offer many features the 4485 SE type burners does not. North American is still developing new models, and enhancements to our classic burners.
4445 TEMPEST ®
The 4445 Tempest® is a small diameter high velocity burner that can be ordered to fit in 9” to 40” thick walls. The 4445-capacity range is 195K to 1.5M Btu/h HHV. They can be ordered with a flame rod, or it can be omitted for UV flame supervision.
4441 TEMPEST ®
Tile exit options including:
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 offers many advanced features, including higher velocity, wider stable operating range and lower NOx options. The high fire capacity range is 0.13M to 5.4M Btu/h HHV.
• Round or slotted ceramic tiles suitable for up to 2900°F operation • Round metal investment cast tiles (HT grade alloy) • Special metal tile option with outside diamter of 3 ¼ " with a capacity upt ot 690K Btu/h HHV Product Highlights: • Stable operation for applications that require excess air or fuel. • Simple inexpensive cross connected control is available over a wider range of operations.
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 Highlights:
• Stable operation to over 40"w.c. air inlet pressure. • Stable operation for applications that require excess fuel. • Simple inexpensive cross connected control is available over a wide range of operations. • Tested with the DMC ultra-low NOx control system. • All 4441's work with UV or Flame rod without modifying the burner.
4575/6575 HIRAM ®
The 4575/6575 HiRAM® burners are low NOx high velocity burners available in larger sizes.
Product Highlights: • Sizes ranging from 4 to 25 million Btu/h HHV for natural gas or propane • Available as the dual fuel 6575 for gas or light oil from 6 to 25 million Btu/h HVV
• Lights with direct spark or pilot (6575 pilot only) • Available with round refractory or metal alloy tiles
