- LOW FINNED TUBE make the spiral which is continuous to the criticism tube and they produce     - LOW FINNED TUBE superficial size width to be widely used with the heat exchanger tube,       compares to the criticism tube and the electric heat efficiency extraordinarily, is excellent.     - The tube and the pin all style is the resistance is excellent about durability and the vibration.     - Becomes heat treatment with OL qualities tube is a cuts, processing etc. bending is easy.     - Unprocessing the tube end Center the part leaving space There is a possibility of selecting rightly       to use.     - shell & tube areas more big compared with tube heat exchanger, compact there is a possibility       that will make produce.     - Condenser and evaporator of air-conditioner and refrigerator     - Condenser of cooler     - Condenser of heat exchanger
