DYNA-PIPE
T E C H N O L O G Y
Design
• Aluminum has high heat conductivity. The
insertion of aluminum extrusion design
maximally enlarges the heat transfer area
with combustion gas.
• The multiple flow channels created by the
aluminum insertion optimize heat exchange
efficiency and maximize turbulence in the
pipe.
Advantages
In Partnership with
• Wide Heat Transfer Areas
• Low Heat Thermal Stress & Low Combustion
Chamber Pressure
• Strong Signal Pressure (i.e. Stable Combustion
at Min. Fire)
• Wide Turndown Ratio with Single Burner
