Protecting cast iron heating systems is a continuous challenge. Homes and buildings with a hot water boiler system struggle with properly maintaining the corrosive cast iron piping and fixtures.  

Water quality is critical to the proper operation of the boiler, cast iron piping, and radiators throughout the building. But, it’s a proven fact that black sludge builds up in the system, reducing performance, damaging the piping and equipment, and causing system failure.

Water Pollutants

Damaging pollutants found in cycled water are the result of hard water, aerated hydronic systems, and poorly maintained boiler, hot water heating systems. Fresh water that cycles through a cast iron heating system contains both oxygen and minerals that can lead to corrosion of the heat exchanger.

Water hardness describes the amount of calcium and magnesium bicarbonate in the water.  In addition, lime scale, a chalky off-white material, is formed within the pipes when calcium carbonate, magnesium hydroxide and calcium sulfite, is heated and then cycled through the boiler, piping, radiators, and equipment. 

The combination of these minerals and debris creates a hard, brownish-black material called magnetite. Sometimes a reddish-brown sludge called hematite is also found causing rust in the heating system. 

These deposits restrict flow in the boiler, clogs pipes, attaches to radiators and heating systems. They reduce efficiency and damage system components. Pollutants and debris take years off the life of a boiler and equipment.

Magnetic Filtering

Professional annual maintenance of your boiler, cast iron piping, and radiator equipment already includes flushing the system and cycling chemical corrosion inhibitors.  

Adding magnetic filtering technology to the maintenance process ensures that virtually 100% of pollutants are removed on the first pass. This unique filtering device passes system water through powerful magnetic rods that draw out and collect hard particles (iron, silica, sodium, and other pollutants) that damage the system. Both magnetic and non-magnetic debris are removed, collected, and destroyed.

Filtering equipment is installed, in-line, in minutes and continuously cleans circulating water as it passes through the magnetic rods. Excessive, damaging debris and pollutants are continuously filtered, collected, and destroyed. Corrosive elements are removed adding life to the boiler, piping, radiators, and equipment.

Magnetic filtering is the next generation of technology that minimizes the corrosive and destructive impact of pollutants. It’s the ultimate filtration.

Flader Goes Skyward

A long-term commercial customer needed an upgrade on their air quality system.It required two 20-ton and two 10-ton Carrier units mounted on the rooftop, plus piping and custom sheet metal inside their manufacturing center. The Flader Team went skyward with a huge crane to land the units on the rooftop.In just 2½ days, the transformation was completed.Click “See our Work” to view more success stories.
