At the Adey booth the MagnaClean Professional2 was showcased, featuring a unique, patented magnetic and non-magnetic filtration system that, within minutes of installation, begins to capture and remove virtually all of the suspended iron oxide that collects in hydronic heating systems. As the popularity of high-performance circulators and boilers increases, the very characteristics that are responsible for that increased level of performance are bringing a new problem to the forefront: iron oxide sludge, also called magnetite. This black sludge, an unavoidable result of oxidation inside untreated hydronic systems, is wreaking havoc in the form of expensive breakdowns and repairs.
And it is not just collecting in the system — it is causing damage. In fact, according to Neil Watson, Adey global technical director, “nearly 70 percent of circulator pumps returned to pump manufacturers fail due to iron oxide and other water quality issues. Data also show that over 95 percent of debris in hydronic heating systems is made up of iron oxide.”
As the magnets pull iron oxide into the circulator, even very small quantities can foul the rotor mechanism. Compounding the problem are the narrower waterways that are now the standard in boilers — smaller-diameter pipes increase efficiency, but clog easily as sludge accumulates. Over time, system efficiency is dramatically reduced, operating costs increase, and expensive damage can result. Designed for ?-in. copper and 1-in. NPT iron pipework, the MagnaClean Professional2 is ideal for residential applications. The MagnaClean Professional2 is a compact unit that is easily fitted on the return pipe to the boiler/circulator, via rapid-fit connectors. It can be installed in minutes, and can be serviced even faster, due to the unit’s quick-release trigger, low-profile drain valve, and built-in air vent.
