Separation efciency
The capacity for separating the impurities in the medium circulating in the
closed circuits of the systems basically depends on three parameters:
1) It increases as the size and mass of the particle increase. The larger
and heavier particles drop before the lighter ones.
2) It increases as the speed decreases. If the speed decreases, there
is a calm zone inside the dirt separator and the particles separate
more easily.
3) It increases as the number of recirculations increases. The medium in
the circuit, flowing through the dirt separator a number of times during
operation, is subjected to a progressive action of separation, until the
impurities are completely removed.
The special design of the internal element in the Caleffi DISCALDIRTMAG
®
magnetic air and dirt separators, are able to completely separate the
impurities in the circuit down to a minimum particle size of 5 μm (0.2 mil),
including 100% ferrous impurities.
The particle separation — dirt separator efficiency graph (left) illustrates
how DISCALDIRTMAG
®
quickly separates nearly all the impurities. After
only 50 circulations, approximately one day of operation, up to 100% is
effectively removed from the circuit for particles of diameter greater than
100 μm (3.9 mil) and on average up to 80% taking account of the small-
est particles. The continual passing of the medium during normal opera-
tion of the system gradually leads to complete dirt removal.
