Flare And Solder Sight Glass For Refrigeration System,Condensing Unit,Refrigeration Unit,Cooling Equipment


Description:

Both Model SGN sight glass and Model SGS sight glass are used on the liquid piping of the refrigeration and air conditioning unit to indicate the flow condition of the refrigerant, water cut of the refrigerant and lubricant oil flow condition of the oil return piping on the oil separator.


Model SGN sight glass and Model SGS sight glass are equipped with one moisture indicator, which will change color to indicate the water cut in the refrigerant.


Model SGR sight glass is used to indicate the level of the refrigerant in the liquid drum and the lubricant oil level in the compressor crankcase.


The modified PTFE sealing is used in bothModel SGN sight glass and Model SGR sight glass, which is applicable to various refrigerants and oils with perfect sealing performance. The structure of both Model SGN sight glass and Model SGR sight glass is an explosion-proof press fit and the viewing glass is clear and safety.


Model SGS sight glass is an independent body structure with conventional sintered glass and O-ring seal.

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 the drier immediately if the color is changed into yellow.
