- In heating and chilled water 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. The dirt separator separates off these dirt particles, circulating within the closed circuit system. These particles are collected in a large chamber, requiring infrequent cleaning, which requires simply removing the magnet ring and opening the large drain valve while the system is running. This device is capable of efficiently removing particles to a very small size, with very low pressure head loss. The DIRTMAG® magnetic dirt separator removes both ferrous and non-ferrous impurities continuously, featuring a powerful removable external magnet around the body that removes up to 100% of the ferrous impurities, including magnetite, that can form in a hydronic system. The DIRTMAG® has 2-1/2 times the removal performance of a standard dirt separator. The body of the NA5453 series separator is made of glass reinforced nylon specifically designed for use in heating and cooling systems. It also is especially versatile as it can be installed on either horizontal or vertical piping with the rotating brass base mount. The NA5453 series is available with conventional union NPT and union sweat connections and the Presscon™ press copper tail-piece with union nut that makes installation and maintenance fast, easy and efficient. Special slots in the EPDM O-ring allows fluid to leak during system testing if unpressed and provide a perfect leak proof seal when completely pressed. Also, models are available with isolation inlet and outlet shutoff valves, which can be used as a dosing point to inject chemical additives into the hydronic circuit.
