The layout of
Induction systems

Many parts – forming a unified whole

Converters, inductors, temperature monitoring – and what exactly do induction systems really look like? Here we describe the layout: which parts belong to a complete induction system and which tasks they fulfil.

Converter

General characteristics of an converter:

  • Provides the necessary energy
  • Determines the possible working frequency
  • Outputs 2 kW to 250 kW
  • Frequency range: 4 kHz to 2 MHz

The outer circuit

Tasks of the outer circuit:

  • For the connection of the inductor
  • Is equipped with capacitors
  • Change of capacitor assembly for tuning the frequency possible (depending on the converter)

Properties of the Himmelwerk outer circuits:

  • Easy to maintain
  • Water-cooled
  • Compact design for space-saving integration

The inductor

Structure of an inductor:

  • Water flowing through copper pipe
  • Geometry is adapted to the component
  • Exact adaptation to component guarantees high efficiency

The water cooler

Task:

  • Closed system for cooling the converter, outer circuit and inductor
  • Ensure a closed cooling water circuit
  • Maintain the quality of the cooling water

The pyrometer

Task:

  • Device for on-contact measurement and regulation of the component temperature
  • Application ranges between 50 and 3000 °C surface temperature possible

The Smart Upgrade

Unique to Himmelwerk: the Smart Upgrade, which allows AI-based verification and checking of compliance with specified limit values for induction heating.

  • A retrofit solution for all AI-based converters
  • Monitoring the inductive processes
  • Identification of error sources
