Chamber Furnaces for Heat Cleaning Gas-Fired with Integrated Thermal Post Combustion

Gas burners for furnace heating and thermal post combustion

The chamber furnaces in the model series NB .. CL are used for heat cleaning of components. An optimum temperature uniformity is not a priority for these processes. Examples are heat cleaning of electric motors, coated surfaces of steel components or the nozzles of plastic injection molding machines. The furnaces are gas-fired and have an integrated thermal post combustion system which is also gas-fired. The pre-set, low-oxygen respectively reducing atmosphere in the chamber furnace effectively prevents spontaneous combustion at the workpiece and subsequent damage as a result of over-temperature. For safe operation, the furnace door locks after program start and cannot be opened again until the temperature has dropped below 180 °C at the process end. In case of a burner flame malfunction or gas shortage the process is aborted. In addition, the control system is equipped with an over-temperature limiter with manual reset that is set by the customer at a safe cut-off temperature to switch off the chamber furnace if the limit is exceeded. The chamber furnaces are not suitable for components and coatings that contain solvents or a high concentration of water. These models must also not be used for charges with low flash points such as wood, paper or wax.
