Tunnel Type Demagnetizer

The Tunnel-Type Demagnetizer is a high-performance magnetic field neutralization system designed to remove residual magnetism from ferromagnetic materials after Magnetic Particle Inspection (MPI) or machining processes. This pass-through coil system efficiently demagnetizes cylindrical, flat, and irregularly shaped parts by applying a controlled AC or AC-DC pulsed magnetic field.

Tunnel demagnetizers are widely used in NDT laboratories, manufacturing plants, automotive industries, and aerospace applications where complete demagnetization is essential for precision assembly and further processing.

Key Features:

High Demagnetization Efficiency – Effectively removes residual magnetism from metals.
Pass-Through Design – Ideal for continuous processing of parts in production lines.
Adjustable Magnetic Field Strength – Allows customization based on material type and thickness.
Multiple Operating Modes – AC or AC-DC pulsed demagnetization.
Handles Various Part Sizes – Suitable for shafts, rods, plates, castings, and welded structures.
Heavy-Duty Coil Design – Provides uniform magnetic field distribution.
Energy Efficient – Low power consumption with optimized coil winding.
Industrial-Grade Construction – Durable frame for long-term, high-load operation.
Meets International Standards – ASTM E1444, ISO 9934-3, and ASME Section V.
