www.ambrell.com Power to 250 kW: Operation from 2 kHz to 6 kHz ekoheat With VPA Technologym World-class Induction Heating Systems EKOHEAT induction heating systems for the 2 to 6 kHz range provide reliable and repeatable solutions for heating with large coils or heating larger parts. Among the many typical applications are heating parts that require deeper heat penetration, heat treating of steels, preheating for forging of steel, aluminum, copper or brass and melting in crucibles. With the versatile EKOHEAT power control system you get rapid tuning, efficient and precise heating of your parts, power control within 0.2% resolution and an easy-to-use, easy-to-read front panel. Remote control is accomplished with 0-10V, 4-20mA inputs, RS485 serial port, 24V controls and remote E-Stop input so integration with your automated production lines is easy. EKOHEAT technology improves return on investment by reducing your energy usage compared to gas-fired and resistive heating techniques. Flameless, non-contact induction heating minimizes energy waste by focusing energy only on the part and zone to be heated. With very efficient power conversion and a power factor greater than 0.9, utility demand charges are reduced, lowering monthly energy bills. EKOHEAT VPA systems are designed on a host/client principle so you can add additional power should your process require it in the future. A separate cabinet houses the resonating capacitor bank, available in several different sizes to meet customer-specific applications. This workhead may be placed up to 30 meters from the power supply. Alternatively the resonating capacitor may be mounted in an extra bay to locate it with the power supply. This is a water-cooled system, requiring connection to a heat exchanger or other means of dissipating heat. The 2 to 6 kHz systems have additional reserve current capability for heating steels through curie.
