KLA-3 Automatic Cloud Point & Pour Point System |
| Test Method Cloud point and pour point are indicators of the lowest temperature of utility for petroleum products. The sample is periodically examined while it is being cooled in the cloud and pour point apparatus. The highest temperature at which haziness is observed (cloud point), or the lowest temperature at which movement of the oil is observed (pour point), is reported as the test result. Features and Benefits • Conforms to ASTM D97, D2500 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 –70°C • Single start/stop push button makes system simple to use • Minimal installation required to set-up software and instrumentation |

| KLA-3 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.

When ordering a multiple configuration system with up to six heads, please specify each measurement head with its associated catalog number using the lowest possible number combination. For example, a two-head cloud point and cloud/pour point system would be KLA-13 and not KLA-31, and a three-head cloud point, pour point, and freezing point system would be KLA-125 and not KLA-152, KLA-215, KLA-251, KLA-512, or KLA-521 On-line version of this product is available. Please contact Koehler Customer Service for additional information.. |
