BENEFITS:
Blend of desiccants
Through constant
engineering research,
Sporlan developed a
blend of desiccants
that gives each core
maximum contami-
nant removal char-
acteristics for today’s
systems. Each core is
formulated with molecular sieve for high
water capacity and activated alumina
for acid removal.A special grade of acti-
vated alumina granules is used to obtain
the maximum ability to remove acids
and products of lubricant breakdown.
The overall result is balanced contami-
nant removal ability.
special charcoal Blend
The HH core, which incorporates acti-
vated charcoal along with other desic-
cants, will remove wax, resins, and lubri-
cant breakdown materials that normal
desiccants do not remove. Therefore,
this type of core is especially useful on
low temperature systems when wax is
suspected in the system or when wax-
like substances are found in the meter-
ing device.
The HH style core has also found wide
application for clean-up after a her-
metic motor burnout where its ability to
remove all types of contaminants is very
advantageous. BE SELECTIVE! Choose a
core designed for the specific application
involved.
The Inside Story
Uniform molding
Sporlan pioneered the molded porous
core. The core is carefully molded to
assure a uniform porosity throughout
the entire length and surface of the core.
The granules of desiccant are carefully
sized and controlled to obtain the proper
porosity for maximum filtration ability.
shockproof assemBly
The core is held in
place by a heavy
leaf spring at
the inlet end
of the Catch-All
assembly. This spring holds the core in
position and makes the assembly highly
resistant to core breakage. The heavy
spring gives a “pre-stressed effect”
that significantly reduces the tendency
of the core to break if the Catch-All is
accidentally dropped.
no Bypassing
The core is sealed to the shell wall at the
outlet end with a gasket or fibrous pad,
which prohibits any possible bypassing
of refrigerant around the core. All the
flow passes through the core for maxi-
mum contaminant removal.
oUtlet safety filter
A final “safety filter” is used in the outlet
of every Catch-All. This involves either a
specially developed polyester pad or 100
mesh screen that collects particles that
might have rubbed off during assembly,
and serves as added protection in case
the molded core is broken.
leakproof shell
The Catch-All shell is tig welded pro-
viding a very smooth, strong, entirely
leakproof joint. The fittings are attached
to the shell by copper brazing. This type
of joint is one of the strongest and most
reliable joining methods known. Each
Catch-All is pressure tested in our facto-
ry to make sure that it does not leak. The
overall result is a Catch-All with strong,
entirely leakproof joints.
QUality fittings
The flare fittings and solder fittings used
on Sporlan Catch-Alls are inspected
100% during manufacture to make sure
no defects are present. The solder fit-
tings are copper fittings with reliable
ID dimension for exact fit to the copper
tubing. Flare fittings are nickel plated
and their surfaces are smooth and free
of scratches. Any imperfect flare fittings
are resurfaced during manufacture.
Be selective
In addition to being manufactured to
high quality standards, the Catch-All
has been designed specifically for field
service work and OEM use. In situa-
tions requiring wax removal or clean-
up after a hermetic motor burnout,
choose the HH style Catch-All core,
which is specifically designed for these
applications.
