The AFX Alu builds on Kelvion’s decade-long experience of customized air fin coolers with aluminum fins. These have a successful track record within the oil & gas industry. To comply with air entrance requirements from API 661, AFX Alu is available in three different heights, 3.1 m / 10.17 ft.; 4.1 m / 13.45 ft., 5.1 m / 16.73 ft. Up to 25 modules in five bays, with five modules in line, can be connected to one cooling unit, to suit operational requirements. Each module is equipped with a forced draft fan blowing the ambient air through the tube bundle. Without mounted steel structure and motors, bays of up to five modules can be transported by truck. The carbon steel or stainless steel tubes with embedded aluminum groovy fins feature a patented shape to maximize the heat exchange surface. This geometry leads to an 8% to 15% improvement in heat transfer at constant power consumption, while providing optimal fouling resistance and cleaning capability. This model is designed for temperatures up to 130°C (266 °F) and pressures up to 15 bar g (217 PSI). AFX Alu has been developed for the cooling of turbo machinery power generation in the fields of heavy industry and oil & gas.
