Selecting liquid line driers for alternative refrigerants.

Author(s) : MELFI J.

Type of article: Article

Summary

The new HFC refrigerants require lubricants that are more hygroscopic than traditional mineral oils, therefore the efficiency of a liquid line drier becomes even more important. Testing drier cores for changes in chemical composition, readiness to absorb and retain volumes of water, and their ability to withstand vibration and attrition, leads the author to the conclusion that certain molecular sieve materials are most suitable. These are referred to as 4A-XH6 and XH9, both of which are in bead form. 4A-XH6 is more liable to attrition and should be used with a compression spring or when little vibration is present. A molecular sieve core is also mentioned. D.W.H.
