EKOHEAT Induction Heating Systems for the 15 to 40 kHz Range

The EKOHEAT induction heating systems for the 15 to 40 kHz frequency range from Ambrell provide repeatable and reliable solutions for heating larger parts that require higher frequencies. Among the many general applications are heat treating of steels, crystal growing, preheating for forging of aluminum, steel, copper, or brass, and heating of graphite and metal crucibles.

With the versatile EKOHEAT power control system, users get fast tuning, a 12-bit power control with a 0.024% resolution, efficient and precise heating of parts, and a user-friendly, easy-to-read front panel. Remote control is achieved with 0-10 V, 4-20 mA inputs, 24 V controls, RS485 serial port, Modbus and remote E-Stop input so integration with your automated production lines is simple. 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 highly efficient power conversion and a power factor greater than 0.9, utility demand charges are decreased, bringing down monthly energy bills. The EKOHEAT systems are engineered for efficient use of cooling water, further minimizing the operating costs. This is a water-cooled system, needing connection to a heat exchanger or other ways of dissipating heat.
