Low fin tubes are specialized heat exchanger tubes designed to enhance heat transfer by increasing the surface area. They feature small, closely spaced fins on their outer surface, typically with a height of about 0.125 to 0.25 inches.
These integral fin tubes are increasingly used in various fluid heat exchangers including coolers, condensers, and chillers. Their design enhances heat transfer efficiency while maintaining a compact structure, typically constructed from durable materials like copper nickel alloys for corrosion resistance.
