dirt separator 56 56 565 series REIE ISO 900 M 65 ISO 900 No. 000 LEI 07/6 N Replaces 07/5 N unction In heating and air conditioning control systems, the circulation of water containing impurities may result in rapid wear and damage to components such as pumps and control valves. It also causes blockages in heat exchangers, heating elements and pipes, resulting in lower thermal efficiency within the system. he dirt separator removes these dirt particles, collecting them in a large collection chamber from which they can be flushed even while the system is in operation. his device is capable of efficiently removing even the smallest particles, with very low head loss. he IRMG magnetic dirt separator removes both ferrous and nonferrous impurities continuously, featuring powerful removable magnets that remove up to 00% of the ferrous impurities, including magnetite, that can form in a hydronic system. he IRMG has ½ times the removal performance of a standard dirt separator. Insulation shells are available separately for brass models.

Operating principle IRL onstruction details he dirt separating action performed by the internal element () offers little resistance to the flowing medium while ensuring dirt separation. he particles collide with the concentric diamond pattern mesh surfaces and then settle to the bottom in the dirt collection chamber (), and not by filtration unlike mesh stainers; which, over time, get progressively clogged. y contrast, the IRL 's low-velocity zone dirt separator function efficiently removes the particles to as small as 5μm (0. mil) with very low head loss. he dirt can then be removed through the bottom drain port (). Low head losses and performance maintained over time he dirt separating action performed by the dirt separator is based on using the internal element () with concentric diamond pattern mesh surfaces instead of an ordinary filter. he element offers little resistance to the medium flow while ensuring dirt separation. his occurs due to the particles colliding with the concentric diamond pattern mesh surfaces and then settling to the bottom, and not by filtration; which, over time, gets progressively clogged. y contrast, the IRL low velocity- zone dirt separator efficiently removes the particles to as small as 5 μm (0. mil) with very low head loss. he dirt collection chamber () at the bottom of the IRL is at the right distance from the inlet and outlet connections that the collected dirt particles are not affected by the swirling flow through the bottom drain port, even with the system running, by opening the drain valve () with the handle (). he collected dirt can then be discharged, even with the system running, by opening the drain valve () with the handle (). 56 56 565M / N565M 565/N565 Geometric structure and large dirt collection chamber he geometrical structure of I R L re d u c e s t h e f l o w media velocity to help separate dirt particles. he dirt collection chamber has the following features: It is located at the bottom of the device at such a distance from the connections that the collected dirt is not affected by the swirl of the flow through the mesh element. I t h a s e n o u g h c a p a c i t y t o increase the amount of dirt stored and therefore decreases the frequency of emptying it compared to filters that need to be cleaned frequently.
Operating principle IRMG Non-ferrous and ferrous impurities, including magnetite, in hydronic systems can deposit onto heat exchanger surfaces and accumulate in pump cavities causing reduced thermal efficiency and premature wear. he small and often microscopic magnetic particles, called magnetite, form when iron or steel corrodes. ighly abrasive, the extremely fine particles are difficult to remove by traditional means. IRMG separators offer highly efficient separation of typical dirt as well as magnetite. he versatile IRMG magnetic dirt separator removes both ferrous and non-ferrous impurities continuously. In addition to removing sand and rust impurities with an internal element in a low-velocity-zone chamber, the IRMG features a powerful removable magnet below the flow line for fast and effective capture of ferrous impurities. he magnet removes up to 00% of the ferrous impurities, including magnetite, that can form in a hydronic system. or the brass IRMG, the ferrous impurities are captured by a strong neodymium rare-earth magnetic field created by a powerful removable magnet around the body below the flow line. or the steel IRMG, the ferrous impurities are captured by a concentrated magnetic field created by a stack of neodymium rare-earth magnets positioned inside a brass dry-well below the flow stream. raining off dirt and ferrous impurities Use of top connector he dirt separator collection chamber has a drain valve. Using the handle provided it is possible to drain off the accumulated dirt particles even with the system in operation. of the dirt separator can be used for optional he connector on top installation of an automatic air vent valve, aleffi code 50 for the threaded or sweat versions, 56 and 56 Series (), replacing the standard /" NP Male plug (code N00). Use aleffi code 5050 for the flanged version 565, N565, 565M and N565M series () replacing the standard /" NP End ap (code 55). or the brass IRMG, captured impurities are easily flushed by unclamping the magnetic collar and purging. I-IREIONL max 0ϒ o purge the ferrous impurities in the steel IRMG, the flexible magnetic stack is removed from the brass drywell and, with the system still running, the drain valve is opened. ided by the system pressure, the dirt and ferrous impurities, including magnetite, flushes out quickly and effectively. max 05ϒ Use of bottom connector he dirt separators come complete with drain valves installed on the bottom port: aleffi code 580 for horizontal threaded or sweat versions, 56 series (); and code N975 (" NP female) for in-line flanged versions, 565, N565, 565M and N565M series (); and code N59600 (" NP female) for free-standing flanged versions, 8" N5650M. Maintenance o perform maintenance, simply use a 6 mm hexagon wrench () to unscrew the dirt collection chamber, of the brass IRL and IRMG, to which the inner mesh element is connected for removal and cleaning.

It increases as the size and mass of the dirt particle increases. he larger and heavier dirt particles drop before the lighter ones.. It increases as the fluid velocity decreases. When the velocity decreases, there is a low-velocity-zone inside the dirt separator and the dirt particles separate more easily.. It increases as the number of recirculations increases. he medium in the circuit, flowing through the dirt separator a number of times during operation, is subjected to a continuous separation, until the dirt particles are completely removed. he special design of the internal mesh element in the aleffi IRL and IRMG dirt separator, is able to completely separate the dirt particles in the circuit down to a minimum particle size of 5 μm (0. mil), including 00% ferrous impurities. he adjacent graph illustrates how these separators quickly remove nearly all the dirt particles. fter only 50 recirculations, approximately one day of operation, up to 00% is effectively removed from the circuit for particles of diameter greater than 00 μm (.9 mil) and on average up to 80% taking account of the smallest particles. he continual passing of the medium during normal operation of the system gradually leads to complete dirt removal. omparison of head losses: dirt separator to Y-strainers Y-strainers entrap dirt within a basket made of stainless steel or brass mesh, selected for the size of the largest particle. Particles smaller than the mesh size may pass through. On most Y-strainers, the basket must be removed periodically to clear the trapped debris. s the debris collects in the basket, flow is impeded resulting in increasing pressure drop and therefore higher head loss. he dirt separation function in the IRL and IRMG utilizes the low-velocity-zone principle. he flow velocity of fluid flowing into the dirt separation chamber is greatly reduced causing the entrained dirt particles to drop due to their density. he internal element provides surfaces that assist in separating dirt particles and guide them downward to ultimately settle to the bottom of the separator. he dirt separator only creates about 5% of the pressure drop of a comparable sized, clean basket Y-strainer, depending on mesh size and amount of filtered debris. hese head losses are not affected by the amount of dirt collected. p (ft. of water)..00.67..67 7 0. 0.067 0.0.00.50..7.00 0 0.0 0.0 0. 0.0 0. 0. 0.0 0.08 0.060 0.05 0.07 0.00 8 56...5.7.98 69 Y-strainer curve / - v=8. 8 97 5. 9.6 67.0 9.5.96 50. 78 5.
