DELLOK Copper Aluminum Extruded Fin Tubes are precision-engineered heat transfer components designed for machinery coolers and industrial heat exchangers. These tubes feature advanced laser welding technology that ensures superior thermal performance and durability.

• Enhanced heat transfer efficiency with increased surface area
• Superior anti-corrosion and anti-wear properties
• Minimal contact resistance for optimal thermal conductivity
• High structural stability under extreme operating conditions
• Excellent anti-fouling capability for long-term reliability

Our advanced laser welding process creates a 100% weld between fin and tube without filler material, ensuring no impurities in the weld seam. This technology provides welding strength exceeding 600 MPa and precision up to 0.05 mm.

• Complete automation with synchronized welding and winding
• Zero contact resistance for maximum heat transfer efficiency
• Heat transfer performance increased by 2.5 times compared to conventional methods
• Fin spacing less than 2.5 mm increases heat transfer area by approximately 50%
• Minimal heat-affected zone preserves base tube integrity

These fin tubes are essential components in various industrial systems including aftercoolers, air coolers, condensers, evaporators, industrial tumble dryers, oil coolers, radiators, and refrigeration systems across multiple sectors.
