Automatic Cold Filter Plugging Point Analyzer with Touch Screen


The cold filter plugging point detection system provides automated
sample testing with the accuracy and repeatability in accordance with
ASTM D6371 and related international test methods. The sample is
cooled according to the pre-selected temperature profile. A 20 mBar
vacuum is applied to the sample at specific intervals across a 45 micron
mesh filter into the aspiration glass cell assembly. If it takes more than
60 seconds for the sample to reach the upper barrier detector or more
than 60 seconds to return below the detector upon release, then the test
is complete and the cold filter plugging point has been reached.

s complete and the cold filter plugging point has been reached.
Integrated Panel PC and Software Package – The KLA Series of
analyzers are complete standalone systems featuring an integrated
panel PC with an advanced software package. The 12” TFT/LCD touch
screen display has a resolution of 1024×768 with a 16.2 M color scheme.
All analytical parameters are graphed and displayed in real time as well
as recorded in Microsoft® Excel compatible file format. The software
monitors the operation and performance of all the analyzer components
for proper data measurement, including the solenoid valves, cooling
system, pressure sensors, and the Platinum resistance PT100 Class A
temperature probe.

Cooling System – For various user applications, the automated
cold filter plugging point system comes standard with cooling for
temperatures as low as -95°C. The direct cooling system features
integrated gas CFC free motors compressors thus eliminating the need
for a solvent cooling bath. The direct system is capable of rapid cooling,
approaching -80°C bath temperatures in approximately 15 minutes, and
utilizes less electricity than standard cooling systems. The rapid cooling
feature combined with a consistent cooling profile system provides
repeatable results with high test reproducibility.

Vacuum System – The automated cold filter plugging point analyzer
includes an internal vacuum generator. The internal vacuum generator
provides a smaller footprint for the complete CFPP system and consists
of a 350 mBar micro-pump and an electronic pressure/vacuum
regulator composed of a proportional valve, pressure/vacuum control
sensor, regulator for reference vacuum generation at 20 mBar and a
vacuum stabilizer.

Multiple Configuration System –These automated sample cooling and
physical property measurement systems can be configured with one,
two, three, four and six test positions with one of five possible analytical
heads at each position: cloud point, pour point, cloud & pour point,
cold filter plugging point and freezing point. Standard and customized
multiple configuration systems are readily available.



Determines the highest temperature at which a given volume of diesel, biodiesel or heating fuel fails to pass through a standardized wire mesh filtration device in a specified time when cooled under specified conditions. The Cold Filter Plugging Point (CFPP) of a fuel is suitable for estimating the lowest temperature at which a fuel will give trouble-free flow in certain fuel systems.
