Magnetic Circuitry is simply how the magnet is designed to attract and retain ferrous contaminants. MPCO utilizes 3 magnetic circuits; Type A, Type B, and Type C.
Type A Circuitry
Type A circuits can be used in applications where the highest level of product purity is required. The circuit utilizes a tube, or a series of tubes, to pull metal from free flowing material that has come in direct contact with the magnets’ working surface. This is why we often suggest multiple rows of magnet tubes in a staggered design. This results in a very high level of tramp metal retention, therefore product purity.
Type B Circuitry
Type B Circuits are best suited to larger product flows where the magnet will need to “attract” tramp metal out of the product stream. The Type B Circuit is designed with more emphasis on the reach-out; but to assist in holding, features such as steps on a plate magnet help tuck tramp metal out of the product stream to keep it from washing off between cleaning cycles.
Type C Circuitry
Type C circuits can be utilized in applications where there are very high levels of tramp metal present, high product flows are required or shut down for cleaning may not be possible. The ability of the magnet to continuously self-clean or retain large amount of tramp through high product flows make it ideal in primary applications where fine tramp metal does not need to be removed.
