Cold Filter Plugging Point
Low-temperature operability is an issue with diesel
fuels because they contain paraffin waxes that
become solid at ambient winter temperatures.
The Cold Filter Plugging Point (CFPP) method is
used to determine the low-temperature operability
of diesel fuel, biodiesel, blends and gas oils. The
CFPP is a critical property used to forecast the
lowest temperature at which a fuel will freely flow
through filters in a diesel engine system.
All diesel fuels contain wax. When the temperature
of the fuel decreases, wax crystals will begin to
precipitate at some point. If a certain amount of
wax precipitates, the crystals can block fuel flow
through filters and other restricted passages in the
Callisto 100 is a fully automated and compact
CFPP tester operated by a touchscreen.
It contains all required components according to
the standard method. Testing and results are in
full compliance with ASTM D6371, EN 116,
EN 16329, JIS K 2288 and IP 309.
Additionally, Callisto 100 can be used for manual
cloud and pour point measurements. With the optional
kit measurements can be performed according to
the standard methods ASTM D2500, ISO 3015,
EN 23015, JIS K 2601, IP 219 (cloud point) and
ASTM D97, ASTM D5853, ISO 3016, JIS K 2269,
IP 15, IP 441 (pour point).
To cool the sample in the cooling jacket an external
cooling system is required. Based on more than
30 years of Anton Paar’s experience in Peltier
element technology, Callisto 100 comes with a
newly developed state-of-the-art Peltier element
technology which allows the connection of a
methanol-free cooling system.

According to the strict guidelines described in the applicable
standards, a given portion of a fuel is cooled under the
specified conditions and is drawn into a pipette under a controlled
vacuum through a standardized wire mesh filter. The test is
repeated when the sample has cooled by an additional 1 °C.
At the temperature at which the sample can no longer be filled
into the pipette within 60 seconds the test is finished, and the
temperature is displayed as the CFPP test result.

There are a number of procedures in refineries
to improve a fuel’s low-temperature operability,
e.g. by treating a fuel with additives or

Callisto 100 is the first choice for evaluating
the quality and drivability of diesel fuels at low
temperatures or even under extreme arctic
These wax crystals may plug the fuel filter,
making it impossible for the fuel system to
deliver fuel to the engine.
Thanks to contact-free infrared detection technology
the complete filtration unit is easily accessible and has
the same detection position in each test. This ensures
high accuracy and repeatability.
Easy and intuitive operation
Start your tests immediately: Callisto 100 comes with
pre-programmed standard test methods to select from the
menu. If you want to customize your test routines, you can
create and store up to 90 individual user programs.
Testing accuracy is enhanced by user-friendly calibration
procedures for the temperature and vacuum – a standard
delivery feature of Callisto 100.
The large color display indicates the sample and jacket
temperature in real time and provides additional graphical
information about the aspiration and flow back times to
observe the temperature behavior of the sample during
For statistics, Callisto 100 offers a result history for
1000 tests as well as the statistical evaluation of test
results according to the test method. Callisto 100
provides versatile connectivity via USB and LAN,
e.g. to export test results as Excel® or PDF files, or
to connect a bar code reader for sample identification.
Easy and Precise CFPP Testing
High sample throughput
Callisto 100 has minimum downtime. Once you have
prepared a second complete test assembly and put it
into the storage place at the rear of the instrument, you
are ready to go for the next test run within seconds.
Convenient cleaning routines
To make the cleaning of the pipette as easy as possible,
a programmable automated cleaning routine can be
initiated at the push of a button.
Excellent homogeneity of the cooling jacket
State-of-the-art Peltier element technology ensures outstanding
homogeneity of the cooling jacket which is the most critical and
decisive parameter for a correct CFPP value determination.
You can also use Callisto 100 for manual cloud and pour point

Thanks to contact-free infrared detection technology, the
complete filtration unit is easily mounted into and removed
from the cooling jacket. This results in the same accurate
detection position for each test and guarantees excellent
repeatability of test results.
The pipette is not shielded and has no thermal insulation.
In addition, Callisto 100 delivers excellent detection, even
when the pipette is frosted. There is no interference from
Extended cooling profiles
In addition to the well-established stepped cooling method,
Callisto 100 meets the requirements of the alternative
standard method EN 16329 with linear cooling of the sample.
The EN 16329 is now part of the EN 590 European Diesel
specification as an alternative test method to EN 116.
Callisto 100 requires an external cooling device:
An inexpensive and methanol-free counter-cooling system
with antifreeze is already sufficient. The cooling system
is only used to support the Peltier elements to reach a
minimum jacket temperature of -70 °C and to measure
samples with a CFPP value below -35 °C.
High flexibility and efficiency
For more flexibility and fast handling, the complete filtration
unit is easily disassembled for cleaning and re-assembled
for the next CFPP test. This cleaning procedure is required by
the standard methods to verify the cleanliness and dryness of
all elements in order to obtain precise test results.
An additional complete test assembly can be prepared while a
test is in progress and stored at the rear of the instrument. This
allows you to start the next test run within seconds, minimizing
the downtime between subsequent tests and maximizing the
throughput for optimized lab efficiency.
