Pittsburgh, PA- As contractors become all too familiar with the damaging effects of iron oxide sludge on today’s high-efficiency commercial hydronic heating and cooling installations (see box below), the need for a solution has been growing. ADEY® Professional Heating Solutions answered that need with the introduction of the MagnaClean® Commercial™ Magnetic Dirt Filter range to the North American market last year, and recently unveiled improvements.

MagnaClean Commercial’s unique, patented magnetic filtration system starts to work immediately upon installation, removing virtually all of the suspended iron oxide that collects in hydronic heating systems. “The removal of iron oxide is facilitated simply by the flow of water through a central magnetic core, which is populated by a series of magnetic rods inside the canister,” says Dr. Neil Watson, ADEY Global Technical Director.
Several pounds of sludge can collect on the magnets, making it difficult to pull all the rods out collectively when fitted through a mounting plate. This year, the ADEY magnet array has been redesigned to allow the rods to be lifted individually; this redesign makes it much easier for the servicing contractor to lift the magnets, particularly in tight spaces. This easy release sequence allows the magnetite from each rod to fall into the base of the filter body so it can be flushed out via the 1¼” NPT drain at the base of the filter. The valve on the flow side can be opened and the debris flushed out through the drain. This product advancement not only makes servicing safer, it also further simplifies the flushing and cleaning routine.
By removing sludge from the system, MagnaClean Commercial restores peak performance and decreases maintenance costs over the life of the system. It also offers a solution for the most common complaints in commercial hydronic systems, including poor system circulation, blocked system pipes and radiators, and excessive system noise.
MagnaClean Commercial filters are available in five inlet and outlet flange size options including 2”, 3”, 4”, 6” and 8”. All MagnaClean Commercial units are designed for use in light-commercial to heavy-industrial applications, and feature cast stainless steel canister bodies containing multiple magnetic rods. Multiple installation options allow for flexibility within any commercial application.
