In hydronic systems, the circulation of water containing impurities may result in rapid wear and damage to components such as pumps and control valves. These impurities also cause blockages in the heat exchangers, heating elements and pipes, resulting in a lower thermal efficiency within the system. DIRTMAG® PRO removes both ferrous and non-ferrous dirt particles from the fluid, collecting them in a large collection chamber, from which they can be drained. This device is capable of efficiently removing even the smallest particles, with extremely limited head loss. The DIRTMAG® PRO dirt separator with dual magnet fields extends the Caleffi dirt separator family by adding a powerful neodymium magnetic pull rod inside a drywell inserted into the top of the body within the flow stream. Additional magnetic flux increases the speed of magnetite (ferrous impurities) removal from the hydronic fluid for maximum protection.
