|KLA-4 Automatic Cold Filter Plugging Point System|
Determines the low temperature flow characteristics of automotive diesel fuels and gas oils, including samples with flow improving additives, by measuring the temperature at which the sample ceases to flow through a wire mesh filter under standard test conditions.
Features and Benefits
Conforms to ASTM D6371 and related specifications
Direct cooling system eliminates the need for solvent cooling baths
One-stage cooling system provides temperatures as low as 35°C and a two-stage cooling system down to 80°C
Single start/stop push button makes system simple to use
Minimal installation required to set-up software and instrumentation

Automatic Cold Filter Plugging Point System
Cold Filter Plugging Point DetectionThe 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 at specific intervals to the sample 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 completed and the cold filter plugging point has been reached.
Advanced Software PackageThe 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 SystemFor various user applications, the automated cold filter plugging 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 80°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 80°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 SystemThese 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.

You may order a multiple configuration system (any combination of freezing point, cloud and cloud/pour point, and cold filter plugging point) with up to six heads. Please specify each measurement head with its associated catalog number using the sequential number combination. A two-headed freezing point system would be KLA-44. A two-head cloud point and cloud/pour point system would be a KLA-13, and a three-head cloud point, pour point and freezing point system would be KLA-124.
