The RatioAir velocity burner with integrated packaged blower is available in four different models, with capacities ranging from 1 to 5 MMBtu/h. Standard-, medium- and high-velocity combustion tubes and block and holder options are available, which enable the RatioAir burners to thoroughly penetrate the load and produce an intensive stream of hot gases that deliver precise temperature uniformity. The unit's ratio regulator automatically compensates for changes in operating conditions and ensures ratio-controlled operation over a turndown range of more than 50:1. The burners can achieve gas velocities up to 500 ft/sec (9,145 m/min) and are suitable for applications that require chamber temperatures up to 2500 F (1370 C).
