Demagnetizing tunnels
After some operations a residual magnetism remains in the material which can cause difficulties at further processing or usage.
One of the demagnetizing methods is by passing the material through alternating magnetic field. For this purpose demagnetizing tunnels with frequency converter are designed. These are used particularly where the other usual methods fail. Our company has developed this custom-built system in order to meet even the most demanding requirements. Currently we are succesfully exporting this technology abroad eg. to Canada, Turkey, Switzerland and Ukraine.
Standard parameters of the demagnetizing tunnels are defined in the table below. For a specific application it is necessary to design a unique device, that will comply with your requirements including needed configuration and parameters.
| Type | Power supply | Frequency converter with current regulation | Intensity of mag. field in the center of empty coil | Size w/h/l mm | Inner size of the coil mm |
