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.
