Bekaert Bekaert Heatexchanger Alucom 7 540 kW 169.781.004

The Bekaert Heatexchanger Alucom 7 540 kW (SKU 169.781.004) is a complete heat exchanger assembly for Alucom 7 boilers with a nominal output of 540 kW. It includes the heat exchanger, burner AR 7140 L-547 VB70, gaskets, inspection window M20, ignition electrode, electrode gasket, nut M4, burner manifold, and stud M4x20. The unit is supplied fully assembled and ready for installation. It is designed for efficient heat transfer in industrial boiler equipment, ensuring stable heating of the heat transfer fluid.

Parts of this type are selected by matching the required thermal output and the physical interface with the boiler body, including flue-gas inlet and water connections. Before ordering, verify the overall length, position of flow and return tappings, and sealing method (gasket or flange). The heat exchanger must be compatible with the combustion chamber depth and the burner's flame configuration. Installation involves connecting the water circuit and ensuring proper sealing.

Heat exchangers of this kind can fail due to corrosion, thermal stress, or blockage from soot or scale, leading to reduced heat transfer efficiency and increased flue-gas temperature. Symptoms include overheating of the boiler, higher fuel consumption, or water leakage. Check for visible cracks, corrosion, or deposits on the heat exchanger surfaces, and verify water flow and pressure.
