| Application | Primary Function | Why Fin Tubes Are Used | Typical Fin Tube Type |
| Air-Cooled Condenser (ACC) | Condense turbine exhaust steam | Water conservation; uses air instead of water in a cooling tower. | Extruded Al on CS, Welded CS |
| Heat Recovery Steam Generator (HRSG) | Generate steam from gas turbine exhaust | Efficiency & Compactness; efficiently transfers heat from large volumes of hot gas. | Welded SS Fins on Alloy Steel Tubes |
| Diesel Genset Radiator | Cool engine jacket water and lube oil | Reliability & Independence; provides self-contained air-cooling. | Extruded Al on Cu/Brass Tubes |
| Gas Turbine Inlet Cooling | Cool intake air to boost power | Power Augmentation; acts as an efficient evaporator coil for a refrigeration cycle. | Al Fins on Cu Tubes |
