ADEY® Introduces MagnaClean Professional2™ – the Solution to a Major Problem Lurking in Hydronic Heating Systems

Effects of Iron Oxide Sludge Can Now Be Virtually Eliminated

 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. Consumers as well as contractors are looking for answers.

“Contractors know there’s a problem,” says Tom Tonkins, Director of U.S. Business Development for ADEY Professional Heating Solutions. “Since the introduction into the North American market of high-efficiency boilers and ECM pumps, both of which have narrow waterways, there has been a significant increase in pump and boiler failures. When contractors service a system, it is evident, in most cases, that iron oxide is present.”

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.”*

What is it about new generation high-performance equipment that makes it more susceptible to sludge? “The new ECM pumps, which have variable speed motors for higher efficiency, have magnets in them… and magnets love magnetite,” explains Tonkins. 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.

Beginning this fall, ADEY, a U.K.-based company launched in 2003, is bringing its proven solution to North America. ADEY’s MagnaClean Professional2features 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. 

Designed for ¾-inch copper and 1-inch 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.

“It’s a beautifully simple device,” says Tonkins. “There are no moving parts. The inlet and outlet are shaped to force a cyclonic-like flow around the magnet, which captures the sludge.”

By removing magnetic and non-magnetic debris, MagnaClean Professional2 not only extends the operational life of the system, but also offers benefits that save money and time for installers and homeowners…

Installer benefitsCompact profile for tight spaces

  • Rapid in-line installation
  • Integral flow-diverters ensure 360° distribution for uniform flow around magnets
  • Powerful permanent magnet with high, first-pass capture
  • Bi-directional inlet and outlet – connect either way
  • Captures non-magnetic debris, such as limescale
  • Rotating filter connections allow customizable installation options
  • Easy dosing of ADEY treatment products via canister
  • Full-flow valves for minimal pressure drop

Homeowner benefits

  • Reduced heating bills
  • Reduced maintenance costs
  • Greater efficiency means a warmer house
  • Design allows for full flow at all times – no loss of pressure or heat
  • Extends system life
  • Zero operating cost
  • No moving parts to replace
  • Reduced carbon emissions 

MagnaClean Professional2 is changing the way contractors work, because customers routinely blame boiler or circulator failure for the problems that are actually the result of the accumulation of system sludge and debris. As a result, contractors are forced to perform countless warranty repairs. “Contractors are saying, Enough is enough. We’re going to offer magnetic filtration technology as a solution. It’s not a big investment, so it’s an easy decision,” says Tonkins. 

ADEY will begin its U.S. rollout of products in October with the MagnaClean Professional2, along with three additional filters sized for other residential and light-commercial applications. ADEY filters are a trusted solution in Europe, and have been installed in over 3 million homes there. They are part of ADEY’s Best Practice System Process, a multi-step routine designed to clean and protect hydronic-heating systems for maximum efficiency.
