DELLOK A216 CS Helical Condenser Extruded Fin Tube is manufactured using advanced extrusion technology that creates seamless, integrated fins directly from the tube wall. This eliminates heat resistance between fin and tube, delivering superior heat exchange efficiency and structural integrity.

Our extruded fin tubes are produced through roll forming technology that transforms the tube wall thickness into straight fins, creating an inseparable bond between fin and tube. This method provides significant advantages over HF welding and wrapping techniques.

Available in single metal and bimetallic configurations:

• Single Metal: Copper (C10200, C12000, C12200), Copper Nickel (C70600), Aluminum (1060), Aluminum alloy
• Bimetallic: Aluminum-Steel, Aluminum-Stainless Steel, Aluminum-Copper, Aluminum-Copper Nickel, Copper-Copper Nickel

• Optimized inner to outer surface ratio for maximum efficiency
• High heat exchange rate with minimal thermal resistance
• Enhanced structural integrity from roll forming process
• Flexible configurations: straight, bent, or coiled heat exchangers
• Strong resistance to vibration, shock, and thermal expansion
• Long service life with cost and energy savings
• Superior anti-corrosion performance

Custom specifications available with annual production capacity exceeding 12 million meters.

Ideal for various industrial applications including:
