Caleffi Hydronic Solutions, a North American pioneer in separation products, now extends its magnetic separator technology to three hydronic product lines: DIRTMAG® dirt separators, DISCAL DIRTMAG™ combination air and dirt separators and SEP4™ combination air, dirt and hydraulic separators. Ferrous oxide forms in hydronic systems when iron or steel corrodes. The abrasive, extremely fine sediment is difficult to remove; it can deposit onto heat exchanger surfaces and accumulate in pump cavities causing reduced efficiency and premature wear. Caleffi magnetic dirt separators accomplish 2½ times the ferrous oxide removal performance of standard dirt separators, delivering up to 95% elimination efficiency.
All Caleffi magnetic products incorporate a powerful, external rare-earth magnet collar around the lower body. Captured impurities are easily flushed by unclamping the collar and purging – even with the system still operating. For further information and documentation, please refer to our online resources at
