Operating principle
The dirt separator operating principle is based on the combined
action of a number of physical phenomena. The internal element (1) is
composed of a set of concentric diamond pattern mesh surfaces. The
dirt in the water strikes these surfaces, separates and drops into the
bottom of the body (2) where they collect. In addition, the large internal
volume of DIRTCAL
®
slows down the velocity of the medium and with the
help of gravity, separates the contained particles.
The collected dirt can then be discharged, even with the system
running, by opening the drain valve (3) with the handle (4).
Construction details
Low head losses and performance maintained over time
The dirt separating action performed by the dirt separator is based on
using the internal element (1) with concentric diamond pattern mesh
surfaces instead of an ordinary filter. The element offers little resistance
to the medium flow while ensuring dirt separation. This occurs due
to the particles colliding with the concentric diamond pattern mesh
surfaces and then settling to the bottom, and not by filtration; which,
over time, gets progressively clogged. By contrast, the DIRTCAL
®
low
velocity- zone dirt separator efficiently removes the particles to as small
as 5 μm (0.2 mil) with very low head loss. The dirt collection chamber
(2) at the bottom of the DIRTCAL
®
is at the right distance from the inlet
and outlet connections that the collected dirt particles are not affected
by the swirling flow through the bottom drain port, even with the system
running, by opening the drain valve (3) with the handle (4).
Geometric structure and large dirt
collectionchamber
The geometrical structure of DIRTCAL
®
reduces the flow media velocity
to help separate dirt particles. The dirt collection chamber has the
following features:
• It is located at the bottom of the device at such a distance from the
connections that the collected dirt is not affected by the swirl of the
flow through the mesh element.
• It has enough capacity to increase the amount of dirt stored and
therefore decreases the frequency of emptying it compared to filters
that need to be cleaned frequently.
• It is easily inspected, by unscrewing it from the dirt separator body for
servicing the internal mesh element when large debris are trapped in it.
