Through Flow Impeders

We offer a wide range of through flow impeders in diameters from 5mm up to 152mm. Through flow impeders are the most common type of impeders and are a relatively simple concept, however at EHE Consumables designs ensure maximum high quality ferrite mass is placed within a well-constructed assembly. The result is improved performance, saving you money and increasing productivity.

All of our impedors are designed to ensure effective cooling and protection of the ferrite core inside the construction. It is essential that ferrite is properly cooled  to maximise welding efficiency and maintain stable parameters for product quality.

Standard through flow impeders – Ferrite is totally enclosed inside the casing

Exposed Ferrite impeders – around 10-15% of the end of the ferrite protrudes from the casing

We have standard male imperial couplings but can offer metric or other threads on request.

EHE impeders are available in length options of 230mm, 330mm & 430mm.

Impeder Cooling

All of our impeders are designed to ensure effective cooling and protection of the ferrite core inside the impeder. It is essential that ferrite is cooled efficiently to maximise the welding efficiency and maintain stable parameters for product quality

Coolant should be clean, preferably filtered. A pressure of 3 bar (45 PSI) will ensure adequate cooling under most operating conditions. Coolant flow requirements vary widely due to inlet temperature, weld power, frequency and weld area geometry. In high power density situations and at high ambient temperatures, a small chiller for impeder and work coil coolant can greatly improve efficiency.
