Caleffi Hydronic Solutions, developer of separation products, has now extended its magnetic separator technology to three hydronic product lines: Dirtmagdirt separators, Discal Dirtmag combination air and dirt separators and SEP4 combination air, dirt and hydraulic separators.
When iron or steel corrode in hydronic systems they form ferrous oxide, an abrasive, extremely fine sediment which 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 2-1/2 times the ferrous oxide removal performance of standard dirt separators, delivering up to 95% elimination efficiency.
Sources say Caleffi’s magnetic products incorporate a powerful, external rare-earth magnet collar around the lower body. Which allows for captured impurities to be easily flushed by unclamping the collar and purging - even with the system still operating.
