Products
Industrial demagnetizers
Based on coils and power modules, these systems are the universal solution for demanding applications. The power and size of the systems are customized according to requirements.
Portable demagnetizers
The MGFE portable demagnetizer is suitable for the mobile demagnetization of larger components, entire machines or complex punching tools.
Special demagnetizing systems
For non standard applications we design customized systems based on our modular construction kit.
Rotating field coils
The RFS demagnetizing devices are particularly suitable for demagnetizing roller bearing rings and disc-shaped parts. Demagnetization is carried out with a pulsed rotating field.
Stray field demagnetizers
Demagnetizing yokes or plate demagnetizers in combination with LM power modules. This increases the output and also enables demagnetization in a pulsed process.
Tunnel demagnetizing coils
Continuous use for operation directly at mains frequency. These coils are suitable for demagnetizing smaller and thin-walled parts.

Demagnetization Services
On-Site Demagnetization Services
When components or equipment cannot be moved without significant effort, or when tight project timelines are critical, on-site demagnetization becomes the most effective solution. PROMAG’s proprietary portable high-power demagnetizer is specifically designed for such demanding applications.
Unique Technical Advantages
Unlike conventional methods, PROMAG employs high-precision low-frequency sinusoidal pulse demagnetization technology, which significantly reduces the risks of induced voltages and currents causing adverse effects on equipment. This ensures that no major disturbances occur to the system.
In practice, this means that demagnetization can be carried out directly on installed equipment—without dismantling sensitive components such as servo motors or sensors—requiring only temporary shutdown during the process.
Tailored Solutions for Challenging Requirements
In certain critical cases, a demagnetizer alone may not be sufficient to achieve the desired results. In such situations, specialized processes and methods are required. With over 20 years of application experience and a commitment to continuous innovation, PROMAG provides safe, effective, and customized solutions to help clients overcome even the most challenging demagnetization requirements.
