Hydrophilic aluminum fin stock, also known as aluminum foil fins, hydrophilic aluminum foil, are mainly used in the production of heat exchanger fins, such as air-conditioning condensers and evaporators, refrigerator frost-free evaporators/finned evaporators, commercial refrigerator condensers and evaporators, automotive air-conditioning condensers and evaporators, etc. Hydrophilic aluminum foil can be surface-coated, usually blue and gold. Flait Aluminum provides hydrophilic aluminum foil for air conditioner are: 8006, 8011, 3102, 1100, 1030B, etc.
