Model SGN
• Be applicable to HCFC / HFC refrigerants.
• Indicate high water cut in system if any.
• Indicate no overcooling in refrigerant liquid.
• Indicate insufficient charging of refrigerant if any.
• Both welded and threaded connections are available.
Model SGR
• Be applicable to HCFC / HFC refrigerants.
• Indicate the liquid level in the liquid drum.
• Indicate the oil level in the compressor crankcase.
• NPT threaded connection.
Note:
For the fully enclosed compressor, generally the allowable water cut is in a range 30~75ppm, but for other types of compressor,
the water cut will be higher slightly. For an effective protection, it is necessary to monitor the indicator carefully and replace
