Burners E m 4 11 Selection criteria Application details The MAXON APX nozzle mix line burner has been especially designed for low temperature air heating applications where standard raw gas line burners MAXON NP AIRFLO are not suitable Thanks to its unique single piece air gas mixing body APX strongly differentiate from the regular box burner with excellent flame stability and flexibility also in high modulating and or low oxygen process air flows Basically APX is available in two main versions A wall mounted APX to be externally mounted on the oven or dryer wall Thanks to the flame that exits the mixing chamber more than 150 mm downstream from the burner mounting flange it is possible to penetrate oven panels up to 150 mm thickness without risking damage to oven structure from flame impingement The in duct APX is installed inside the dryer or make up air unit to heat up low temperature process air flows Available APX versions and options The two basic APX versions wall mounted and in duct are available in several variations Below tables give an overview of the different options of each version Note that wall mounted APX burners are always mounted on suction side of circulating fans or in balanced ducts Whether slot or continuous flange mounted burner should be selected depends upon the desired amount of cooling purge air around the burner The packaged blower option is not available on
