EHX-03A Induction Heater

EHX-03A is a compact, lightweight, and portable induction generator (induction heater) designed to work with air-cooled inductors. The device combines high power with a small form factor, making it an ideal solution for mounting and dismounting applications in the field and in workshops.

The EHX-03A offers high output power with a form factor several times smaller than previous mid-frequency generators. The device works with both flexible (Flexible) and fixed (Fixed) inductors—allowing you to heat elements of various shapes (e.g., gears, couplings, bearings) or conduct repetitive heating cycles on specific parts.

Technical Specifications (Selected Data)

Technical specifications and detailed data can be found in the manufacturer's product datasheet

Key Features

• Output Power: 22–30 kW
• Lightweight and mobile design — easy transport between workstations
• Designed for use with air-cooled inductors
• Supports Flexible and Fixed Inductors
• Capability for repeatable heating cycles for serial operations

Practical Applications

The EHX-03A is used in many industrial processes, including:

• Dismounting and mounting components — heating bearings, sleeves, couplings
• Heating gears and clamping rings before mounting/dismounting
• Service work in railway depots (e.g., dismounting a wagon wheel) using fixed inductors
• Production applications requiring repetitive, controlled heating

Examples of applications and previously developed heating cycles are available from the manufacturer.

User Benefits

• Shorter service time due to fast and controlled heating
• Higher process repeatability — reduced result variability
• Mobility: the device is easy to move between work stations
• Lower installation requirements compared to larger medium-frequency systems

How to choose the right model and inductor?

When choosing an induction system, pay attention to:

• Power required for the task — match the model and power (22 or 30 kW) to the mass and material of the component being heated.
• Inductor Type — a flexible inductor allows heating irregularly shaped elements; a fixed inductor ensures repeatability in production.
• Cooling — the EHX-03A is designed for use with air-cooled inductors; check that the inductor and working conditions ensure proper heat dissipation.
• Mobility and ergonomics — in service conditions, it is important that the device is easy to move and connect.

Documentation and Safety

Before commissioning the system, familiarise yourself with the technical datasheet, operating manual, and the manufacturer's safety requirements. Induction devices operate at high temperatures and voltages — appropriate health and safety procedures and operator training are required.

FAQ — Frequently Asked Questions

What components can I heat with the EHX-03A?

Typical applications include heating bearings, gears, sleeves, couplings, and other metal components requiring localised heating for mounting or dismounting. :contentReference

Is the EHX-03A safe to move around the workshop?

Yes — the device's design is mobile and weighs about 39 kg, which facilitates transport between work stations. However, appropriate precautions must be taken when lifting and moving.

How to choose between a flexible and a fixed inductor?

The choice depends on the task: use a flexible inductor for complex geometry elements and one-off repairs; choose a fixed inductor when you require repetitive heating cycles in serial production.
