Hydronic heating and cooling systems work perfectly when the liquid medium within is purely as intended with no foreign particles or gasses. Once air, corrosion products or metallic particles are present the integrity is compromised and liable to damage. Magnetic Filters, Deaerators and Dirt Separators are used to continuously eliminate the air and dirt contained in the hydronic circuits of heating and cooling systems.
Mechanical dirt and air separators can be supplied separately or combined. The fluid can be passed through several media like mesh or pall rings to cause the air to rise to the top and/or the dirt particles to sink to the bottom. These unwanted materials can then periodically decanted and disposed of or released back to the atmosphere.
The air discharge capacity of these devices is very high. They are capable of automatically removing all the air present in the system down to micro-bubble level. At the same time, they separate dirt and impurities contained in the water in the circuit and collect it in the lower part of the valve body, from where it can be drawn off. To take the deaeration to another level, vacuum degassing can be utilised to take any air in solution out too. Completely deaerated water circulating through the system allows it to function under optimal conditions without encountering problems of noise, corrosion, localised overheating or mechanical damage. Boilermag high performance filters have been carefully engineered to provide lasting protection for larger heating and cooling systems. Powerful magnetic circuits combined with optimised fluid flow dynamics ensure that virtually every particle of magnetite (sludge) is removed on the first pass through the filter.
