Heat Exchanging Copper Alloy / Copper LL type  Finned Tube for Water Tank in Solar Systems

LL-type finned tube
LL-type finned tube makes the trapezoidal cross-section forming by rolling combine closely with the heat flux density distribution size. The fins combine tightly with the tube,which makes the thermal efficiency higher and put an end to thermal resistance that brings by the non eliminate contact from segment gap of the string type finned tube.
Working temperature: 230 ℃
1 Features:
The winding technology improves production efficiency and heat transfer, makes the average fin pitch and higher proportion between fins and tube. At the same time, the base tube can be protected from air erosion.
2 Application:
LL-type finned tube mainly used in petrochemical, electric power, paper making, tobacco, building heating and other industry such as air cooler, air heater and air heater of food industry, plant starch spray drying system.
