Heating & Cooling System Protection

All heating and cooling systems are at risk from magnetite (black sludge) which forms when air and water reacts with ferrous components. Left unchecked, this can seriously reduce energy efficiency and cause premature failure of components, resulting in high maintenance costs.

High performance systems for Residential, Light Commercial and Commercial Properties

BoilerMag high performance filters have been carefully engineered to provide lasting protection for larger heating and cooling systems. Powerful magnetic circuits combined with optimized fluid flow dynamics ensure that virtually every particle of magnetite (sludge) is removed on the first pass through the filter, thereby improving efficiency and protecting system components.


Ideal for systems in:

  • Educational buildings
  • Healthcare buildings
  • Municipal buildings
  • Apartment blocks
  • Office buildings
  • Retail premises
  • Factories
  • Hotels

Full Flow Design – filters 100% of water on first pass

A full flow filter is fitted in-line within the main circulation, hence 100% of system water passes through on each pass. It is vital that magnetite is extracted immediately from the circulation before it reaches the boiler. The alternative side stream filter method allows magnetite (sludge) to circulate several times and may never be captured.

A Choice of Filters

The range includes the BoilerMag filter which is ideal for residential installations with 1” NPT (1-1/4” NPT adaptors included) or Press connections, the BoilerMagXL filter which is ideal for medium sized properties with 1½" connections, while the BoilerMagXT range is ideal for heavy duty commercial heating and cooling systems with 1½" up to 12" connections. The range also includes system treatment chemicals and electrolytic scale reducers.
