EKOHEAT 75 kW through 250 kW induction heating systems

Power to 250 kW
Operation from 2 kHz to 6 kHz
World-class Induction Heating Systems

EKOHEAT 75 kW through 250 kW 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.

Versatile

♦ Efficient heating of many part geometries, sizes and compositions
♦ Multiple capacitor configurations
♦ Multiple tap transformer configurations
♦ Voltage or Power control
♦ Repeatable, reliable heating, agile frequency tuning
♦ Through-Curie heating
♦ Movable workhead; up to 30m (100’)
♦ Sub-second to continuous cycle times
♦ Remote operation or logging with RS485 port
♦ Accepts international AC line voltages

Easy to Use

♦ User-friendly operator front panel controls
♦ System configuration from front panel
♦ Cycle timer, peak and short-cycle data capture
♦ 10 ten-step heating profiles
♦ Overload-tolerant output management
♦ 5-language display suite (EN, ES, FR, DE, IT)
♦ System diagnostics displayed on front panel

EKOHEAT is CE marked and manufactured at our IS0 9001:2015 certified facility.

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.

The 2 to 6 kHz systems have additional reserve current capability for heating steels through curie. Alternatively, the resonating capacitor may be mounted in an extra bay to locate it with the power supply.

The EKOHEAT 75 kW through 250 kW systems are water-cooled, requiring connection to a heat exchanger or other means of dissipating heat.
