Unique Magnetic Filtering Solutions for a Unique industry wide Problem
We were contacted to trouble shoot a boiler system that was short cycling.
The picture below is a scale sample taken during an annual water side boiler inspection.
After being descaled, the boiler ran longer and exhaust temperatures dropped dramatically. The before and after, boiler efficiency was restored from 62% back up to 93%. The efficiency calculations were based on measurements of the liquid condensate being expelled at the flue exhaust, along with 02 & CO2 combustion analysis.
Magnetite is nearly eight times more insulative than regular Calcium-Magnesium based scales. This is one of the reasons we see many heat exchanger failures in the boiler and DHW heating industry.
Magnetite is a highly-insulative material and reduces heat transfer due to its density.
What is Magnetite
Magnetite is a term used in the HVAC industry used to describe the fine, dissolved metal held in a heating system, often seen in the form of black iron oxide, or sludge. The effects of the sludge is to narrow the waterways of the gas fired boilers and water heaters. The deposits tend to build-up internally in low flow areas of the system and where the heat is highest. Scale will continue to gradually build-up inside of the waterways until being restricted, or in extreme cases blocked entirely causing overheating, and eventual heat exchanger failure.
Can Magnetite be safely removed?
Absolutely, HydroCleanse can quickly remove Magnetite and dissolve Calcium/Magnesium based scales with our standard blend. Custom formulations can also be created to safely clean many different materials and scale types. Our filtering systems can extract magnetite 24/7 to prevent on-going accumulation within hydronic loops.
System Water Quality is Critical to Extend Heat Exchanger Life, and Maintain Peak Efficiency in Commercial Boilers, Domestic Water Heaters and Chillers
HydroClean Service LLC. are industry innovators in hydronic heating system maintenance and water treatment solutions. We have developed a complete range of system remediation and prevention products to help you prevent system contamination, maintain system performance, and extend the life of your boilers & domestic water heaters.
​
The best option of preventing magnetite damage would certainly not to let magnetite form in the first place. however, there is not much chance. Even when the system materials are corrosion-resistant and the system is chemically treated regularly.
​
the only effective and practical solution to reduce magnetite in heating water is fitting a dirt separator fitted with powerful magnets. The working principle is quite simple. The heating water flows through a cylinder. As flow enters the cylinder the flow velocity is reduced, so non magnetic particles can deposit successfully. Collecting on the filter media inside the separator chamber. In addition, the heating water flows around a magnetic rods integrated in the separator. The tiny magnetite particals suspended in the water attach to the rod. the liquid flow is not influenced by by these measures, no major resistance is present. to dispose of the foreign matter a maintenance specialist simply pulls out the magnetic rods from the filter housing, opens the bottom drain on the separation chamber, and the sludge can flow out without making a mess.
​
We offer several effective size range filtering solutions for protecting hydronic heating systems from the ever growing magnetite and scale problem plaguing building owners, operators, and boiler manufactures. The installation of a magnetic filter is most effective when combined with a filter media and also accompanied with corrosion inhibitors to protect the system from oxygen corrosion, along with monitoring to ensure the parameters are being maintained.
​
HydroMAG filter utilizes multiple powerful Magnets and a filter polyester media design to capture debris down to the finest Debis passing through your system to protect gas fired equipment and maintain heating systems from being contaminated. The Magnetite particals can be as small as 8 microns.
​
In HVAC there are many conventional controls to protect boilers, components, equipment, etc. However, we typically see little to no controls on the water quality side of the system. We at HydroClean Services are looking to break that trend with our new innovations. We offer a combination monitoring (from your SCADA, PLC or controller) and filtering system integrated and packaged into the filter housing. We have the optional capability to monitor DP indicating filter replacement, PH level, Conductivity, Nitrite PPM (corrosion inhibitor levels) Temperature, Like your boiler controls, your system water will now be monitored 24/7 through a remote H20 dashboard and provide alarms and data analysis.

Light commercial & Industrial Applications System - Boilers, Pumps, Equipment Benefits:
• Restores systems efficiency and performance, up to 30% more efficient than in an untreated system.
• Equipment Maintenance costs are reduced and the 304L or 316 SS canister assembly can be used as a dosing pot across all models.
• Collects large and small magnetic and non magnetic scale particals. Our Filters can capture down to 5 microns.
• Compatable with hydronic, heating and cooling system loops,
• 5 in 1 unit - Shot feeder, magnetic filter, air separator, side stream filter and water system monitoring.
• Bottom hose connection used to connect a hose and flush system contaminants to a floor drain, avoiding mess.
​
We can help you with sizing and identify where in the system to best apply these filtering technologies. We have many diagrams to make the process simple.

How much magnetite is inside your boiler?
Call us and schedule an appointment for a complementary water side inspection, and see how much is Magnetite and scale is inside your boiler and water Heater.
On Average we remove 2-4 Pounds of magnetite from a single 2,000 MBH Boiler.
