Small and often microscopic magnetic particles called magnetite form when iron or steel corrodes. Highly abrasive, the extremely fine sediment is difficult to remove by traditional means. Caleffi’s SEP4, DISCALDIRTMAG and DIRTMAG separators capture magnetite with a concentrated magnetic field. Dirt and magnetite is quickly flushed out of the drain valve when the magnet is removed while the system is operating. The DISCALDIRTMAG combination air and dirt separator removes micro-bubbles, dirt and magnetite, plus the SEP4 provides hydraulic separation. All have 2 1/2 times the magnetite removal performance of standard separators, delivering up to 100% elimination efficiency.
