Product Description
DELLOK High Frequency Welded Longitudinal Fin Tube Air Heater
DELLOK specializes in manufacturing high-performance longitudinal finned tubes using advanced high-frequency welding technology for superior heat transfer efficiency in industrial applications.
Manufacturing Excellence
Established in 2002, DELLOK operates with 200+ employees and 33 technical staff across 47 fin tube production lines, including an imported McElroy production line from America. Our annual production capacity exceeds 12 million meters with comprehensive quality control throughout the manufacturing process.
Product Overview
Longitudinal finned tubes deliver exceptional performance in heat transfer applications, particularly in petrochemical industries. These tubes serve as the core component of heat exchangers, utilizing resistance welding technology to attach U-shaped fin strips directly onto the tube surface.
Key Advantages
Enhanced Heat Transfer
Provides 8 to 12 times the heat transfer area of bare tubes, significantly improving thermal efficiency.
Space Optimization
Enables smaller, more compact heat exchangers while maintaining superior performance.
Cost Efficiency
Reduces equipment costs and operational expenses through improved heat transfer and reduced pressure drop.
Structural Integrity
Increases tube stiffness and enhances seismic performance while reducing metal consumption.
