Freeze/Cloud Point Process Analyser FRP-4/4-CPA

The freeze point as well as the cloud point are both important cold properties that need to be monitored by operators. Cloud point and freeze point can be detected with one analyser as the principle of detection is identical. The difference between the two properties is defined by the actual sample behavior. The sample, for example, gasoil, is cooled down and below a limit certain small crystals start to appear, which results in a certain degree of cloudiness to the sample. At that point the so-called cloud point temperature is determined via reduction of light intensity through to optical path. 

The cooling process is stopped and the crystals dissolve again. The sample becomes clear and transparent again. As soon as all crystals have dissolved the freeze point temperature has been reached.

Application

These cold properties are important therefore for the aviation industry, hence jet fuels and other aviation gasolines to avoid filter clogging or irregular combustion characteristics during surgery of turbines. The same applies to, for example, gasoils and diesel products.
