Automatic Cloud Point & Pour Point System
Cloud Point Detection – The cloud point detection system provides
automated sample testing with the accuracy and repeatability in accordance
with ASTM D2500 and related international test methods. The sophisticated
dynamic measurement system emits a light pulse every 1°C from a coaxial fiber
optic cable positioned above the test sample. The light pulse is then
reflected off the silvered-bottom test jar to an optical sensor. The advanced
software package analyzes the response of the light pulse. The initial
appearance of crystallization is monitored by light scattering, signifying
the cloud point of the sample. All clear and transparent oils are readily
measured by the detection system, regardless of sample color.
Pour Point Detection – The pour point detection system provides
automated testing with the accuracy and repeatability in accordance with ASTM
D97 and related international test methods. The automated operation includes
the removing the sample from the cooling jacket at 3°C intervals and tilting
it to a 90° angle as prescribed by the test method until no flow is observed.
Contact of the cold sample with the two Pt-100 temperature probes positioned
just above the surface liquid level when the test jar is tilted identifies
sample flow. The test jar is automatically returned to the cooling jacket and
sampled again until no flow is detected for 5 seconds. The pour point result
is then reported at 3°C higher than the temperature at which the sample
ceased to flow in accordance with the test method.
Advanced Software Package – The Windows®-based software package can
control either a stand-alone system or provides multiple analyzer networking
with a single network control station. All analytical parameters are graphed
and displayed in real-time as well as recorded in Microsoft® Excel file
format. The software monitors the operation and performance of all the
analyzer components for proper data measurement, including the solenoid
valves, cooling system, other moving parts, as well as the Pt-100 temperature
probes and the pressure sensors. The calibration curves for each probes and
sensors are displayed individually and saved to the hard disk with date and
time of test.
Cooling System – For various user applications, the automated cloud
point and pour point systems are available with either one-stage cooling for
temperatures as low as –35°C or two-stage cooling for temperatures as low as
–70°C. The direct cooling system requires no solvent cooling bath and thus
eliminates operator exposure to solvents used in standard cooling systems.
The direct system is capable of rapid cooling, approaching –70°C bath
temperatures in approximately 15 minutes, and utilizes less electricity than
in standard cooling systems. The rapid cooling feature combined with a
consistent cooling profile system provides repeatable results with high test
reproducibility.
Multiple Configuration System – These automated sample cooling and
physical property measurement systems can be configured with up to six test
positions with one of five possible test heads at each position: cloud point,
pour point, cloud & pour point, freezing point, and cold filter plugging
point. Standard and customized multiple configuration systems are readily
available. Please inquire with Koehler Customer Service about product
specifications and ordering information.
PC Configuration– Operation of the software package requires the use
of a PC, which should be ordered separately. Please inquire with Koehler
Customer Service if assistance is needed in procuring a PC. The PC should
have the following minimum requirements: Pentium III 800 MHz processor, 128
MB RAM, 2 GB hard drive, CD-ROM, Windows® 95/98 operating system, Microsoft®
Excel, Windows® keyboard, monitor, mouse, graphic and video cards.
