Flexfire NBD Series

Modular Duct Burners for Low Temperature Heating

FlexFire NBD series burners are designed to operate in low-temperature applications where a high turndown ratio and shorter flame length are required. FlexFire series burners are modular, with each 300mm module generating 250KW output. FlexFire burners are integrated directly into the ductwork of existing HVAC systems or industrial processes.

  • Modular Architecture: Built using standardized 300mm modules, allowing flexible configurations to fit any duct dimensions.

  • High Turndown Ratio: Delivers precise thermal output control for varying heating demands.

  • Short Flame Profile: Ensures maximum heat transfer efficiency within compact duct spaces.

  • Multi-Gas Fuel Compatibility: Supports Natural Gas, LPG, and Biogas operations seamlessly.

  • Low Pressure Drop: Minimal resistance to airflow inside ductwork for optimal fan efficiency.
