Application: Low fin tube is mainly used in air-conditioners, condensers and evaporators of refrigeration equipment, absorption refrigerator, oil cooling container and other heat exchangers.  It is also applied in thermal power plant, condersers and evaportors of heat exchangers in nuclear plant, condensers and evaporators of ship-used heat exchangers, air coolers of gas turbine, petroleum industry, diesel cooler, aftercooler, desiccators and heater in all chemical industry.  Low fin tube is made from continous rotary fin through light pipe. Compared with light pipe, low fin tube has lager extenior area and better heat-transfer character, so it can be widely used in many heat exchange situations.
