"Dry" Nitrogen Gas Charging for Refrigeration Applications
"Dry" Nitrogen Gas Charging for Refrigeration Applications
(OP)
Our gas charging specification calls for "dry" nitrogen gas, but I don't know how "dry" the nitrogen needs to be. I know that different grades of nitrogen contain different amounts of water vapor; I was wondering if anyone could give me a specific dryness standard for nitrogen gas charging in refrigeration applications (e.g. < 1 ppm H2O).

However, this is the quality of the supplied nitrogen from the factory. Some unique application will use added dryers (silica gel) to lower the water and hydrocarbon ppms.
