Finned tubes

The most frequently used 5- types of finned tubes for Air fin coolers are:

L-fin helical

Tube material tube: carbon steel, stainless steel
Fin material: Aluminium (ALU)
The ALU-fin has an L-shaped base, and is in contact with the carbon steel tube itself.
Working temperature: up to 150°C

Knurled “L” wrap on finned tubes - helical

Tube material: carbon steel, stainless steel
Fin material: ALU
Working temperature: up to 250°C

G-fin helical

Tube material: carbon steel, stainless steel
Fin material: ALU
The ALU-fin is crimped into a groove in the basic tube.
Working temperature: up to 400°C

Extruded – Bimetallic - helical

Material tube: carbon steel
Material fin: ALU
The fins are extruded from a basic ALU-tube that previously encased the carbon steel inner tube.
Working temperature: up to 250°C

TIG welded finned tubes

Tube material: carbon steel, stainless steel
Fin material: ALU, carbon steel, stainless steel
High frequency welded tubes for high temperature conditions >400 °C

Spiral Tension Edge Wound for non conventional cooling or heating.

Spiral tension edge wound finned tubes are mainly used for the heating of houses or large spaces, but also for industrial applications as heat exchangers. .

We fabricate in house spiral tension edge wound finned tubes with the base tube and the fins out of carbon steel or stainless material. These finned tubes are produced in nearly each length.

Working temperature is up to 150°C.
