Optimal filtration with magnetic filters
Protecting systems from harmful particles is essential to maintaining performance and extending the service life of critical components. By integrating magnetic filters into Ditech’s filter housings, mechanical and magnetic filtration are combined into one efficient solution. This approach delivers superior particle retention, reduces wear on equipment, and lowers overall maintenance requirements.
What is a magnetic filter?
A magnetic filter is a device that uses high strength magnets to attract and capture metallic particles from fluids. Magnetic contaminants such as iron oxides and metal fragments are drawn to the magnetic surface and retained there, preventing them from circulating within the system.
Magnetic filters are available in various sizes and magnetic strengths, depending on the application and the level of contamination in the fluid. They are commonly used in industrial systems, heating and cooling installations, hydraulic systems, and process water applications to ensure reliable operation and protect components from wear and blockages. By installing a magnetic filter, the risk of operational disruptions is reduced, equipment service life is extended, and the need for frequent servicing and maintenance is lowered. This helps protect pumps, valves, and other system components from damage caused by metallic particles that would otherwise circulate within the system.
Did you know?
Black water in a closed energy system was previously regarded as an indicator of a stable, oxygen free installation. In reality, it is a warning sign. The dark colour is caused by suspended magnetite particles, a corrosion by product that can block valves, reduce heat transfer, cause excessive wear on pumps, and increase energy consumption. Even in low oxygen systems, magnetite can gradually accumulate and create blockages if it becomes dislodged and starts circulating. This can lead to operational issues and unforeseen costs.
Magnetic filters provide an effective way to prevent this. Conventional particle filters do not always capture metallic particles, whereas a filter with an integrated magnet attracts and retains them. The result is cleaner water, reduced wear, improved operational reliability, and the potential for energy savings of 5–15%.
Magnetic filters in combination with bag filters
For optimal filtration performance, magnetic filters can be used in combination with bag filters. This configuration provides effective multi stage filtration, where the magnetic filter captures metallic particles before the fluid passes through the filter bag. This reduces the load on the bag filter, lowers stress on the filtration media, and results in extended service life and reduced operating costs.
Bag filters are highly effective at removing particles of varying sizes, but they do not always capture magnetic contaminants. By combining these filtration methods, a more comprehensive filtration solution is achieved, particularly in systems where both metallic and non metallic contaminants are present. This approach is especially well suited for industrial applications, process water, chemical processes, and other demanding environments where clean fluid quality is critical.
How does a magnetic filter work inside a filter housing?
A magnetic filter is installed inside the filter housing and acts as an additional barrier against metallic particles. As the fluid flows through the housing, particles are drawn toward the magnets, where they are captured and retained. This ensures more effective filtration and protects the system from contamination.
Choosing the right filter housing for magnetic filtration
Ditech offers a wide range of filter housings that can be tailored to specific requirements. Material options such as stainless steel (304L, 316L) and Duplex provide high corrosion resistance and long service life, while various pressure ratings ensure reliable performance in demanding applications.
Benefits of magnetic filters in Ditech filter housings
- Efficient removal of metallic particlesMagnetic filters capture even the finest metallic particles, helping to prevent wear and potential damage to system components.
- Extended service life of the primary filterBy reducing the amount of metallic particles reaching the main filter, its service life and efficiency are increased, resulting in lower operating costs.
- Reduced maintenance and downtimeFewer particles circulating in the system lead to reduced maintenance requirements, improved operational reliability, and less unplanned downtime.
- Compatibility across multiple applicationsDitech filter housings with magnetic filters are suitable for a wide range of industries, including industrial applications, marine & Offshore, aquaculture, and water treatment.
- Environmentally responsible solutionAs magnetic filters do not require disposable filter elements, they help reduce waste and contribute to lower operating costs.
