The DIRTMAG PRO is an inline, multi-pass device that continuously removes
impurities (a.k.a. “dirt”) with each pass of the hydronic system fluid. This
dirt comes from pipes that are not properly cleaned and flushed before
connection, and from installation scraps such as copper shavings, pipe tape
and solder balls. Pipe scale and corrosion over time also create dirt, all which
adversely affect heat transfer efficiency, component performance and reduce
the life expectancy of mechanical system components such as valve and
circulator bearings and seals.
The DIRTMAG PRO has two powerful magnetic fields to capture ferrous
dirt, and a particle separation mesh to capture non-ferrous dirt. The dirt is
then easily and quickly purged from the system using a simple “blow down”
valve located at the bottom of the DIRTMAG PRO barrel. No disassembly
or scraping magnetite from wetted magnets is needed, which means clean
hands and fast easy servicing.
Operating principle
The DIRTMAG PRO patented technology includes unique dual magnetic
fields, one in the flow path and another in the large-barrel low velocity
zone. The dual fields increase ferrous particle removal efficiency by
40% which means faster removal of magnetite and other ferrous debris
with each fluid pass. Faster removal increases protection for boiler heat
exchangers, circulator bearings and valve seals. Up to 100% of ferrous
debris is removed.
The flow path magnetic field comes from a powerful and unique
retractable magnetic pull rod inside a top-mounted brass drywell. The
magnets themselves are not wetted; when removed the ferrous material
is released from the drywell exterior and falls to the bottom of the barrel
until purged.
Unlike most “magnetic filters” on the market today, the DIRTMAG
PRO also has a large concentric-pattern dirt separation mesh in the
low-velocity flow path which removes non-ferrous debris as small as
5 microns. The mesh uses deflection and gravity to capture particles
which then settle in the lower area of the barrel until they are easily
purged from the system.
The DIRTMAG PRO efficiently removes all types of unwanted dirt,
ferrous AND non-ferrous debris. It keeps the hydronic fluid clean so
boilers, heat pumps and circulators (the most expensive equipment
in the system) remain performing at high efficiency and will not suffer
damage caused by poor fluid quality due to debris.
Relative to cost of ownership, blow down of the debris collected by
the DIRTMAG PRO is fast and easy, especially when compared to the
laborious and messy task of disassembling, cleaning and reassembling
a wetted magnet device. Simply remove the magnetic pull rod from its
drywell, unclip the external barrel magnetic collar, and open the integral
purge valve. Once the fluid turns clear, close the purge valve, replace the
magnets and the system is back in service. The “no-mess” task takes
perhaps a minute or two, compared with 10 to 30 minutes required to
do the same for a wetted magnet product. The system maintenance
cost savings can be very significant and an otherwise dirty job becomes
a clean and easy job for contractors.
