A client contacted THE LAB at Ambrell needing to heat aluminum impeller blades to 200 ºF (93 ºC) and shrink fit them onto shafts. THE LAB determined that an Ambrell EASYHEATTM 3.5 kW, 150-400 kHz induction heating system would be best for this induction shrink fitting application based on the client's requirements. The frequency for the application was determined to be 255 kHz.
