Selas Hi-Lo Torches are atmospheric gas burners designed for high turndown ranges on all types of combustion chambers or furnaces operating under a negative pressure.
Combustion chamber draft induces all combustion air. No air blower or mixer is required. Atmospheric type venturi correctly proportions air and gas flows and delivers uniform mixture to burner nozzle.
Exclusive pressure actuator controls burner nozzle stabilizer disc with changes in gas flow to maintain stable flame. A single modulating gas valve controls fuel pressure automatically.
High efficiency Selas AN type nozzles used on each assembly provide excellent flame retention at all firing rates and drafts.
Hi-Lo Torches are available in three assembly options. Assemblies “B” and “C” include a burner mounting cage complete with secondary air adjustable shutter and tapped holes for precision mountings of pilots and flame detectors.
The simplicity of an atmospheric torch combined with the high turndown actuator provides an easily adjustable system requiring little if any maintenance.
