Automatic Freezing Point System
Freezing Point Detection–The freezing point detection system provides
automated sample testing with the accuracy and repeatability in accordance
with ASTM D2386 and related international test methods. The sample is cooled
in the test chamber with constantly stirring. The sophisticated dynamic
measurement system emits a light pulse every 0.5°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. The sample is then warmed
up, and the temperature at which the hydrocarbon crystals disappear is
recorded as the freezing point. All clear and transparent fuels are readily
measured by the detection system, regardless of sample color.
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 freezing
point system is 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.
