The icon scientific Freeze Point Analyzer provides an indicator of the lowest
ambient temperature at which an aviation jet fuel can be used. Using advanced
cryo-cooling, it can measure freeze points down to -80°C.
- Easy to use: with an armored glass wipe-clean touch-screen and intuitive multi-lingual graphic user interface.
- Certified to global standards: ATEX, IECEx, TIIS, EAC, and ETL approved to give absolute confidence and peace of mind in hazardous areas and manufactured under an ISO9001:2015 certified Quality Management System.
- Robust and fully explosion proof: no air or inert gas purging required for safe operation in explosion hazard areas. Safety assured: with an alarm for internal sample leakage.
- Highly efficient: with low sample consumption and a sample flow monitor.
- Flexible: with auto validation or calibration options and standard Modbus, 4-20mA, and digital contact outputs.
What does the Freeze Point Analyzer do?
The icon scientific Freeze Point Analyzer provides an indicator of the lowest
ambient temperature at which an aviation jet fuel can be used. Using advanced
cryo-cooling, it can measure freeze points down to -80°C. Like the Cloud Point Analyzer, it features the icon scientific low mass measuring cell and a vacuum insulated cell housing. This patented system helps improve cooling performance and eliminate condensation, ice formation and the effect of stray light. The vessel features detection systems to monitor the vacuum and alert you to any sample leakage. The results are compatible with those of any standard freeze-point test methods such as ASTM D2386, D5972 and ASTM D7153. Additionally, the analyzer can perform very low cloud point measurements without the external chiller units required by peltier-based Cloud Point analyzers for these applications.
How does the analyzer work?
The low-mass measuring cell traps a small amount of the sample that is then cooled at a controlled rate by the cryo-cooler. The cooling process continues until the optical detector picks up sufficient light-scatter from precipitating wax crystals, indicating that a cloud is forming. At this point, the cell of the Freeze Point Analyzer is allowed to warm up; the temperature at which the cloud disappears is taken as the freeze point. The sample cell is then flushed with a new sample and the cycle is repeated.
Why choose the icon scientific Freeze Point Analyzer?
- Excellent repeatability: with advanced detection algorithms, it generally achieves better repeatability than the standard test methods.
- Reduced thermal losses: the cell within the Freeze Point Analyzer is equipped with an LED light source and photo diode detector; air-gapped light guides eliminate physical and thermal contact between the light source, detector and the cell, thereby reducing thermal losses.
- Best in class cooling performance: reduced thermal losses, coupled with the low-mass measuring cell and patented vacuum insulation system, enable the maintenance-free cryo-cooler to cool to -100°C using normal plant-cooling water.
