Description
ASTM A179 Carbon Steel Extruded Fin Tube For HVAC Economizers
HVAC Economizers (Flue Gas/Air Heat Exchangers) are installed in the flue ducts of boilers/chillers, with A179 extruded fin tubes as the core component:cold water/fresh air flows inside the tubes, while high-temperature flue gas passes outside the tubes.Fins of fin tubes increase the outer surface area by 8–12 times, with heat transfer efficiency far exceeding bare tubes.ASTM A179 has high thermal conductivity (45–50 W/m·K), excellent pressure resistance, high ductility (suitable for extrusion process).

Some Important Advantages of A179 Extruded Fin Tubes for HVAC Economizers

Medium and Low Temperature Conditions: The temperature resistance limit of aluminum fins is approximately 260°C (500°F), perfectly matching the flue gas temperature of HVAC boilers.

A179 High Cost Performance: 50–70% lower cost than stainless steel and copper-nickel alloys.Compact Design: Smaller equipment size under the same heat transfer capacity, saving machine room space.
Applications of A179 Extruded Fin Tubes
Economizers supporting gas/oil-fired boilers
Industrial Plant HVAC: Waste heat recovery for hot water/steam boilers
District Heating/Cooling: Combined heat and power (CHP) systems
Heat Pumps and Chillers: Evaporators/condensers of flue gas heat pumps.
