G fin

G fin is embedded fin, also known as a Grooved fin.
The strip is embedded in groove on the surface of tube
and tube grabbed the strip.
This mechanical bond stengthen the unity of fin and tube.
The strip is efficient heat conductivity at the high
temperature relatively.
Maximum working temperature : 400℃(750℉)
Material of fin : Aluminum, copper

LL fin

LL fin is overlapped footed fin.
It has the similar specification to L fin.
It is used widely as an alternative to the extruded
fin in a highly corrosive environment.
The overlapped footed fins protext corrosion
effectively.
Maximum working temperature : 165℃(330℉)
Material of fin : Aluminum, copper

L fin

The strip of L type realizeds the optimum ground
pressure of fin foot and tube.
it improves the heat conductivity and has efficient
anticorrosion.
Maximum working temperature : 130℃(270℉)
Material of fin : Aluminum, copper

KL fin

KL fin is with knurled foot.
It's same as L fin except knurled foot.
The connection of knurled foolted fin and tube
strengthen the mutual combination by mechanical bond.
And it also improves the heat conductivity efficiently
Maximum working temperature : 260℃(500℉)
Material of fin : Aluminum, copper
