EKOHEAT Induction Heating Systems for the 50-150 kHz Range

Ambrell’s EKOHEAT induction heating systems for the 50-150 kHz range provide consistent and repeatable solutions for high-speed heating of smaller parts where the coil size or the part geometry requires high frequency for efficient heating. Among many general applications are shallow case depth hardening, heat treating of steels, and heating of steel, copper, aluminum, or brass for brazing, shrink fitting, forming, curing, and melting.

The versatile EKOHEAT power control system provides users with efficient and precise heating of parts, fast tuning, power control within 0.2% resolution, and a user-friendly, easy-to-read front panel. Remote control is achieved using 0-10 V, 4-20 mA inputs, 24 V controls, RS485 serial port, and remote E-Stop input so integration with your automated production lines is easy. The EKOHEAT technology enhances return on investment by decreasing energy usage compared to gas-fired and resistive heating methods.

Flameless, non-contact induction heating lowers energy waste by directing energy solely on the part and zone to be heated. With very efficient power conversion and a power factor more than 0.9, utility demand charges are decreased, bringing down monthly energy bills. The EKOHEAT systems are built for efficient use of cooling water, thus additionally lowering the user’s operating costs. This is a water-cooled system, needing connection to a heat exchanger or other ways of dissipating heat.
