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 it generates 250KW output. FlexFire burners are designed for low temperature applications i.e- air handling units, spray dryers, industrial ovens etc.
FlexFire burners are integrated directly into the ductwork of an existing heating, ventilation, and air conditioning (HVAC) system or industrial process for low-temperature applications.
