6 Proven Benefits of Sporlan
Solenoid Valves
-
Molded coil for most sizes.
-
Class
F temperature rating --- Coil types MKC-1,
MKC-2, and OMKC-2.
-
Extremely
rugged, simple design --- few parts.
-
E
Series may be brazed without disassembly.
-
Tight
closing through use of synthetic seating
material.
-
Can
be used on Refrigerants 12, 22, 134a and
502 because of high MOPD ratings.
Sporlan
Solenoid Valves and made in two general
types, normally closed and normally open.
The normally closed types may be further
sub-divided into direct acting and pilot
operate types.
The
Sporlan E series solenoid valves feature
extended solder type connections as standard.
One important benefit to the user is that
all valves in the E series can be installed
without disassembly using either low or
no silver content brazing alloy. The :E
series is interchangeable with the existing
B series solder type valves providing
the overall length can be accommodated.

CRANKCASE PRESSURE REGULATING
VALVES
|
|
|
|
|
| |
|
|
Crankcase Pressure Regulation Valves are designed
to prevent overloading of the compressor motor
by limiting the crankcase pressure to a predetermined
maximum value during and after a defrost cycle
or normal shut-down period. These valves automatically
throttle the vapor flow from the evaporator
until the compressor can handle the load.
Sporlan manufactures
four adjustable model. All are available with
to adjustment ranges of 0 to 60 and 30 to
110 psig. All models respond only to their
outlet pressure and modulate to prevent the
suction pressure at the compressor from rising
above the valve setting. Since these valves
are adjustable, the setting may be altered
to suit the specific system requirements

The Sporlan line of discharge bypass valves
are designed to provide an economical method
of compressor capacity control in place of
cylinder unloaders or to handle unloading
requirements below the last step of cylinder
unloading. These modulating control valves
automatically bypass the required amount of
discharge gas to the low side to maintain
the desired minimum evaporator pressure.
The valves
are applicable on any refrigeration or air
conditioning system that operates during periods
of low load, which can result in coil icing
or short cycling. These valves respond to
downstream pressure changes and open when
the evaporator pressure falls below the valve
setting. At normal loads and evaporator conditions,
the valve remains closed and the system operate
in a conventional manner.

Unique molded porous core

of a blend of highly effective desiccants
-
The
quality features built into it assure
years of services on any refrigeration
system
Moisture
The Filter-Drier removes moisture from
the refrigerant by absorbing and retaining
it deep within the desiccant granules.
The CW line ( New series) is designed
for use with the polyester oils and features
approximately twice the water capacity
of a standard.
Foreign Matter
The Filter-Drier will filter out scale,
solder, particles, carbon, sludge, dirt,
or any other foreign matter with negligible
pressure drop. Fine particles that would
go through an ordinary strainer are removed
down to the minimum size in one pass filtration.
The large filtering area of the Filter-Drier
core permits it to collect a large amount
of dirt without plug up.
|
|
|
| |
Acid The Filter-Drier is
unexcelled in acid removal ability. The hydrochloric,
hydrofluoric, and various organic acids are
absorbed and held by the desiccant in a manner
similar to the absorption of moisture. Tests
have demonstrated that the Filter-Drier will
remove over 20 times as much acid as the desiccant
used in most driers. This ability, along with
its excellent ability to clean up the oil, is
responsible for the excellent field performance
in cleaning up severely contaminated systems.
Oil Sludge and Varnish
The Filter-Drier will filter out scale, solder,
particles, carbon, sludge, dirt, or any other
foreign matter with negligible pressure drop.
Fine particles that would go through an ordinary
strainer are removed down to the minimum size
in one pass filtration. The large filtering
area of the Filter-Drier core permits it to
collect a large amount of dirt without plug
up.
Special Application
A special HH core Filer-Drier is available
to remove wax which frequently causes difficulty
on low temperature Refrigerant 22 and 502 systems.
RememberIts not
how much moisture you remove from a refrigeration
system that counts, its how little moisture
is left.. |

Moisture and Liquid
Indicator
Offers these 8 outstanding benefits.
-
One indicator for refrigerants 12,
22, 134a, 500 and 502.
The Moisture and Liquid Indicator
provides a true moisture indication for
either Refrigerant 12, 22, 500, 134a, or
502. The dark green indicates dry and a
bright yellow indicates wet. The one indicator
avoids the confusion found in those makes
with 2 elements. You cannot pick the wrong
element when checking the moisture content
of system.
|
|
|
| |
-
Reliable
and Accurately Calibrated Color Change Points.
The Moisture and Liquid Indicator
is accurately calibrated in parts per million
of moisture for each refrigerant. All moisture
indicators change color on the basis of
relative saturation of the refrigerant.
Therefore, liquid line temperature must
be considered if an accurate calibration
is to be obtained. A color chart is part
of the label, for easy comparison.
- Color changes are easily distinguished
and reversible.
The indicators color differs
so widely between WET and DRY conditions that
there is no possibility of confusion between
the two. Colors will reverse as often as moisture
concentration in the system changes.
- Large full view sight glass.
The Moisture and Liquid Indicator
has an extra large crystal clear sight glass
for viewing the refrigerant. Bubbles indicate
a shortage of refrigerant or a restriction
in the liquid line.
- Indicator protected from discoloration
and dirt.
The indicator is protected by
a filter pad and screen. This prevents washing
of the indicator by the refrigerant and protects
it from system contamination and turbulence.
- Replaceable indicator element.
The color indicator paper can
be changed on the new fused glass models without
removing from the line. Replacement is thru
the bottom.
- Disassembly of the smaller sizes
not required.
The extended steel fitting on
solder models in the smaller sizes make it
unnecessary to disassemble for installation
since steel conducts only one eighth as much
heat as copper.
- A double duty plastic cap
is supplied to keep the glass
free from dust, dirt, and grease. It also
permits the service engineer to use his own
discretion concerning instructions to his
customers on observing the Moisture and Liquid
Indicator.

Sporlan offers an exclusive concept in suction
filter design a filter which is bi-directional.
When flow is in the direction of the upper arrow,
the bypass relief feature is active. If the pressure
drop across the element becomes excessive, the
bypass relief will open slightly to maintain sufficient
gas flow and assure proper cooling of the hermetic
motor.
When
the Suction Filter is installed with flow in the
direction of the lower arrow, the bypass relief
feature is inactive and will never open, regardless
of the increase in pressure drop. The access valve
is used on these latter applications to measure
the pressure drop across the felt element to the
suction service valve on the compressor |

REPLACEABLE SUCTION FILTER
|
|
|
|
|

|
|
A replaceable element shell,
used with a pleated filter element, installed
in the suction line of new systems to remove
residual contaminants.
-
Recommended for supermarket systems.
Low pressure drop.
-
Can
be use with desiccant cores for clean-up
after burnout.
-
Various
fitting sizes up to 3 1/8 line size.
-
Access
valve supplied for pressure drop measurement
or charging.
HOW
IT'S USE Sporlan Replaceable Suction
Filters are installed in the suction line
of refrigeration or air conditioning systems
to remove contaminants that may be in the
system at startup.
The Replaceable
Suction Filter has large fittings permitting
the use of a small size shell on a system
with large line sizes, resulting in considerable
economy. The angle construction is suitable
for flow in either direction, which results
in easy installation even on compact racks.
The Replaceable
Suction Filters can be used temporarily with
cores for cleaning up a system after a hermetic
motor burnout.
