EWS converter
Using the EWS converters developed by
KVT Bielefeld GmbH
,
metallic components
(insert heat element) such as thread inserts are heated without contact by elec-
tromagnetic energy.
A strong very local magnetic field is built up inside the EWS converter using a mid-
frequency high alternating current. Eddy currents are produced in the insert heat
element by this magnetic field. The insert heat element is heated in seconds by the
eddy currents.
The temperature that the insert heat element is heated to ban be adjusted for the
duration of the heating and the position of the insert in the converter during the
heating. This temperature can be reproduced very precisely. The optimal heating
parameters are determined by
KVT Bielefeld GmbH
using temperature measure-
ments.
The EWS converters must be integrated in the cooling circuit. The converter can on-
ly be protected from overheating and thus destruction by a sufficient coolant flow
rate.

Caution! A coolant flow rate that is too small can result in over
heating and thus destruction of the ERW converter.
