Fin Tubes
Core Features & Advantages

Robust Construction

Available in durable combinations: Aluminum fins on Copper tube (Al/Cu) for HVAC/R, Copper fins on Copper tube (Cu/Cu) for high conductivity, or Aluminum fins on Carbon/Stainless Steel tube (Al/CS, Al/SS) for corrosive/industrial environments.

Optimized Fin Designs

Precision-formed L-foot, LL-foot, G-foot, or Embedded fins ensure excellent fin-to-tube contact integrity and low thermal resistance.

Reduced Fouling & Pressure Drop

Engineered fin spacing (typically 8-16 FPI) balances heat transfer efficiency with minimized air pressure drop and dust accumulation.

Corrosion Resistance

Options include protective coatings (epoxy, hydrophilic), specific alloy choices (e.g., 3003 Al fins, SS tubes), and protective collars.

Custom Engineered

Tailored solutions for tube material, diameter, wall thickness; fin material, height, thickness, pitch (FPI); bundle size, and circuiting to meet exact thermal & mechanical requirements.
Key Application Focus

HVAC & Refrigeration

Core component in air-cooled condensers, evaporators, DX coils, heat pump coils, and air handlers for efficient building cooling/heating.

Industrial Heat Exchangers

Vital for air coolers (ACUs), charge air coolers (CACs), oil coolers, economizers, and process gas coolers in power plants, chemical processing, and manufacturing.

Energy Recovery Systems

Used in heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs).
