A client contacted THE LAB at Ambrell because they needed to heat a steel tube and an aluminum block for a cylinder liner coating curing application in the automotive industry. THE LAB did testing and determined that an EKOHEAT^® 30 kW, 50-150 kHz induction heating system equipped with a remote workhead would be optimal for this application. The target temperature for the application was 400 °F (204 °C). Two coils were used for this application: a single position two-turn channel coil and a single position four-turn helical coil.
