Tunnel demagnetizer with a belt conveyor TOSD
Tunnel demagnetizer is suitable for installation in automated processes. Thanks to the compact design and high efficiency in demagnetizing the tunnel is recommented for demagnetization of mass production parts (like moulds, shafts, ball bearings, cast iron pieces etc.)
The demagnetizing tunnel eliminates (by generation of gradually decreasing AC in coils) residual magnetism (the penetration depth is limited and some extremely hard products need a special version of the demagger). The belt conveyor as well as the tunnel degausser can be delivered in various dimensions and with various types of power supply.
We recommend the table demagnetizer SO for quick manual demagnetization of tools and flat or small cylindrical workpieces handled by hand; the hand demagnetizer RO is the right choice where the workpiece cannot be brought to the unit — such as moulds, bearings or parts of machinery. For batch demagnetization in automated production lines, we supply the tunnel demagnetizer TO, or the TOSD with an integrated belt conveyor for continuous operation.
Table and hand demagnetizers generate a demagnetizing field of up to 40 mm above the working surface; the table model DEM-4 Easy Logic handles even large, solid workpieces within this range thanks to its automatic power regulation. The tunnel demagnetizers TO and TOSD remove residual magnetism using a gradually decreasing alternating field; for materials with high hardness we supply a special version of the unit.
Yes, we supply the tunnel demagnetizers TO and TOSD in various sizes and supply voltages so they can be built directly into existing conveyor systems. The compact design of both units allows installation even in space-constrained production environments; we will assess the installation site and propose the optimal configuration.
The key parameter for effective tunnel demagnetization is maintaining the optimal throughput speed of approximately 0.2 m/s. The TOSD model has the conveyor directly integrated in the unit and maintains this speed automatically; for the tunnel demagnetizer TO, the correct speed depends on the settings of the existing conveyor system.
Standard tunnel demagnetizers TO and TOSD operate using a gradually decreasing alternating current in electromagnetic coils; for workpieces with high material hardness we offer a special version of the unit with adapted output. The SO series table models are equipped with a dual coil with unlimited duty cycle and automatic regulation that adjusts to the shape and size of the workpiece.
We offer the table demagnetizer SO in four variants: DM 3 (250 × 180 mm), DM 4 (280 × 266 mm), DM 5 (400 × 306 mm) and DEM-4 Easy Logic (280 × 280 mm) — all rated 220 V with a power consumption of 352 W. The choice of model depends on the dimensions of the workpieces to be demagnetized; we will recommend the right type for your application.
Demagnetizers are used primarily in metalworking, mechanical engineering and foundries, where residual magnetism interferes with machining or assembly of components such as moulds, bearings and shafts. Table and hand demagnetizers are designed for demagnetizing tools and workpieces in the workshop, while tunnel units handle batch demagnetization of mass-produced components in automated lines.
