Standard Series of Assembly Through Flow Impeders

Standard sizes of through flow (T/F) assembly impeders based on ferrite cores issued by TDK (Japan) and intended for a high-frequency tube welding.

Standard Series of Assembly Through Flow  Impeders

Though flow impeders intended for a high-frequency tube welding are most widely used as compared with other types of impeders. Due to a fact that electromagnetic parameters of ferrite core are strongly dependent on temperature, it is extremely important to have a reliable and effective cooling system.

To provide a reliable cooling system, it is recommended to develop a pressure of cooling emulsion flow that is passed though impeder not less than 2.75 bar. To improve an operational life time of impeder and to provide an optimum operation of impeder, it is extremely important to organize a reliable system for filtering a cooling emulsion.

In production of impeders one or several ferrite cores of TDK are usually used.

USM Company produces standard models of assembly through flow impeders having diameters from 5.4 mm to 74 mm and a length of 230 mm, 330 mm and more.
