Using the kinetic energy of higher gas pressures, the Series “HG” Mixing Tube provides a thoroughly blended air/gas mixture. The higher gas pressure allows use of a lower pressure combustion air blower. In combination with a MAXON MICRO-RATIO® flow control valve and combustion air blower, the “HG” Mixing Tube can provide localized mixing of air and fuel to single or multiple industrial burner systems. Adjustment is simple through single point proportioning.
