What is low finned cooler tube?

A low finned cooler tube typically refers to a type of heat exchanger tube rather than a component of an evaporative cooler. These tubes are used in various heat exchanger applications where efficient heat transfer is crucial. 

Low finned tubes have external fins with a lower height compared to standard finned tubes. These fins increase the surface area of the tube, enhancing heat transfer between the fluid inside the tube and the surrounding air or another fluid. 

While evaporative coolers do utilize heat exchange principles, they typically rely on a different mechanism involving the evaporation of water to cool air, as you mentioned earlier. So, low finned cooler tubes wouldnt be directly associated with evaporative coolers, but they are important in other industrial cooling processes.

Low finned cooler tube material grade and production standard:

1. ASTM B111 / ASME SB111: These standards cover seamless copper and copper alloy heat exchanger tubes for surface condensers, evaporators, and similar heat transfer apparatus. The material grades specified include C12000, C12200, C44300, C68700, C70600, and C71500.

2. EN12451 / EN12449: These European standards also cover copper and copper alloy tubes for heat exchangers. Material grades such as Cu-DLP, Cu-DHP, CuZn28Sn1As, CuZn20Al2As, CuNi10Fe1Mn, and CuNi30Mn1Fe are included.

3. BS British Standard: British standards, such as BS EN 12451 and BS EN 12449, also cover copper and copper alloy tubes for heat exchangers. Material grades CZ106, CZ111, CZ110, CN102, and CN106 are specified.

4. JIS Japanese Industrial Standards: Japanese standards, including JIS H3300, cover copper and copper alloy seamless pipes and tubes. Material grades C1201, C1220, C4430, C6870, C7060, and C7150 are part of these standards.
