Overview
LV AIRFLO® Duct Burners provide high turndown heating with natural gas, propane and many other fuels. The innovative, progressive aeration pattern of the LV adds to system efficiencies by operating on extremely low duct pressure drops reducing overall system horsepower required. With several material varieties provided, the LV can be used in applications up to 1200°F (650°C) and may even be used as a natural draft burner. With over 55 years of experience in duct burner applications and construction, MAXON provides positive assurance of successful heating solutions. Contact MAXON today to discuss your combustion needs for burners, burner management systems or complete prepackaged combustion systems.
Features & Benefits:
Features & Benefits:
- Series LV AIRFLO® burners provide stable, efficient, raw gas operations in air streams with relatively low duct velocities
- Duct static pressure drops may be as low as 0.2” wc
- Produces clean and odor-free combustion with natural or propane gases
- Air stream temperatures upstream of a Series LV AIRFLO® burner can be up to 1050°F
- Low air stream oxygen levels can be tolerated without a need to add primary combustion air to the system
- Modular burner design provides burner assembly configurations and total heat release for maximum application flexibility
- 17 varieties of Series LV AIRFLO® burners available, each optimized in materials and/or performance factors to match your specific application requirements
