Founded in 1986 MHD Magnets is currently the leading manufacturer of patented magnetic fluid treatment systems. Years of R&D and the adaptation of known magnetic applications have resulted in four product lines:

• Magnetic modules for scale control in pipelines;
• Magnetic separators removing metallic particles from fluids;
• Biofilm monitoring and control of MIC (microbiology induced corrosion) and bio fouling;
• Centrifugal separators removing magnetic and non-magnetic particles from fluids.

Since 1994 the MHD focus has mainly moved to the magnetic separators product line. The PACMAN separator design has been developed and is continuously improved upon. MHD’s extensive track record with more than 200 successful installations proves that the PACMAN design offers the best available magnetic technology to efficiently remove magnetisable particles from fluids by combining the highest possible magnetic flux density with low fluid velocities. Since the introduction MHD has improved every aspect of the separator’s performance making it the most reliable and effective and hence largest selling separator in its category.

In 2010 a new separator, the ROTOMAG, was introduced. This second line separator is specially designed to remove almost all ferritic particles from the effluent coming from the PACMAN inline magnetic filter in order to save process fluid and energy.

Quality workmanship, automated operation and a patented internal cleaning system complement the MHD high gradient magnetic separators. All permanent magnetic separators are specially designed and constructed to efficiently remove metal parts from fluids customary in automobile manufacturing metal pre-treatment plants. Other industries with great potential for this technology lie in coil coating installations, chemical processes, lubricants, cutting oil systems, cooling water systems and in the food & beverages industry.

The use of magnetic fields interacting with minerals in solution to control scale forming precipitation of these minerals in chemical or heat exchange systems is a far more abstract application of magnetic technology. However, MHD has been quite successful in the application of magnetic modules in a number of zinc phosphate stages in automobile manufacturing lines. This success of the FLOWMAG is slowly becoming a new but proven technology in these environments where the costs of aggressive cleaning chemicals and spent labour hours are becoming more and more a maintenance headache.
