Product Overview

Construction details
Engineered polymer
The dirt separator is constructed of a polymer specifically selected
for heating and cooling system applications. The main features of the
composite polymer are:
- high strength to strain, while maintaining good ultimate elongation
- good resistance to crack propagation
- very low humidity absorption, for consistent mechanical performance
- With continuous medium flow, the polymer has a high resistance
to abrasion
- Continuous performance over wide temperature variations
- Compatible with glycols and additives used in circuits.
These basic material characteristics, combined with the optimal
body design in the most highly stressed areas, provides operating
performance equivelant to metals typically used in the construction
of dirt separators.
Operating principle
The operating principle of the magnetic dirt separator is based on the
combined action of a number of physical phenomena.
The internal element (1) consists of a set of radial reticular surfaces.
As the water or glycol solution strikes these surfaces, the impurities
are separated, dropping into the bottom of the body (2) where they
are collected.
Ferrous impurities, including magnetite, are trapped inside the dirt
separator body, attracted by powerful magnets (3) inserted into
a special removable outer ring. The large internal volume of the
DIRTMAG
®
slows down the velocity of the medium and with the help
of gravity, separates the contained particles. The collected dirt can
then be discharged by removing the magnetic ring and opening the
drain valve (4); this procedure can be performed while the system is
in operation.

Low pressure losses and performance maintained over time
The dirt separating action performed by the dirt separator is based on
using the internal element with radial reticular 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 radial reticular surfaces and then settling to the bottom, and not
by filtration; which, over time, gets progressively clogged. By contrast,
the DIRTMAG
®
low velocity- zone dirt separator with magnet efficiently
removes the particles to a very small size with very low pressure head
loss.
