The sight glass with a moisture indicator can tell what the moisture content is in the system. Combined refrigerant sight glass like other models of the refrigerant sight glass is generally green in color to represent the absence of dangerous water vapor in the refrigerant and yellow in color to represent the high water vapor content in the liquid line.
If it flashes add refrigerant.
Refrigerant sight glass color. The refrigerant sight glass changes color. Its the best means of determining the presence of moisture in the refrigeration system. A quick glance at the glass and youll know if a problem exists.
Almost all glasses have moisture indicators. The indicators change colors depending upon the amount a moisture in the refrigerant. If the green color starts to fade the moisture content is reaching a critical level.
If the color changes to yellow it is a clear signal that the capacity of the filter driers is exceeded and should be replaced as soon as possible. If the operating conditions of the system are normal the refrigerant fluid appears liquid through the glass of the. Simple Simple Simple Right.
Theres Volumes Of Infomation On Display. The refrigerant sight glass provides a ton of information. When I first began work in the field I thought it was so simple.
If its clear youre OK. If it flashes add refrigerant. First make sure you are aware that older sight glasses may not be sensitive enough to pick up wet conditions with HFC refrigerants that contain POE oil.
Second when installing a sight glass keep it sealed as long as possible before installing. If you open the indicator to air prematurely it may change color due to moisture in the air. The sticker on the side of it has the color green with Dry typed over it and the color yellow with wet typed over it.
Inside the sight glass in the middle there is a 14 diameter material. Does the thing in the middle turn to a green color if there is not enough refrigerant and turn yellow if refrigerant goes over it. If it turns yellow is this what is meant by charging to a clear sight glass.
Green color indicates the refrigerant is DRY and yellow indicates a WET condition. The indicator is formulated so that it changes color at the moisture levels generally accepted as the safe operating range. The SeeAll calibration information in Table 1 is based on.
The plain sight glass is used to observe the refrigerant as it moves along the line. The sight glass with a moisture indicator can tell what the moisture content is in the system. It has a small element in it that changes color when moisture is present.
What you see in the sight glass can help you diagnose system malfunctions. This allows the installer or Servicer to observe the state of the refrigerant in the sight glass in place. When moisture pointing to the CD will include as shown here it becomes moisture pointing to the sight glass.
This mechanism allows the mechanic to determine the amount of moisture in the refrigerant circulating through the system. Chemical compounds on the drive sits in the refrigerant flow and change color. You could be looking at a discoloured sight glass or the real colour of the refrigerant.
What does the semi compressor oil look like. Either way pump down and fit a good quality drier and if the sightglass comes apart clean it or replace it. - This and all of the sight glasses should be located as close as normal the refrigerant fluid appears perfectly liquid underneath the lens of the indicator.
The presence of bubbles indicates that the refrigerant fluid is partial evaporating along the liquid line. - The sight glass will show bubbles if the system is low on refrigerant. I have always taken a black Sporlan sight glass to mean that the system is contaminated with dissolved motor insulation or other ugly compounds that can be formed in an unclean system.
I have seen a sight glass return to a dark green color after a contamination cleanup - new refrigerant liquid line filter-drier oil change if possible and a solid low-micron evacuation and dehydration. Combined refrigerant sight glass like other models of the refrigerant sight glass is generally green in color to represent the absence of dangerous water vapor in the refrigerant and yellow in color to represent the high water vapor content in the liquid line.

Contents in the refrigerant. The colour on the sight glass indicator depends on the moisture content of the refrigerant. The values under green dry are to be considered as perfect condition meaning full protection against harmful effects from moisture.
In other words the filter drier is working perfectly. Colors Large clear viewing area MIACIAAMI sight glass with grooves to distinguish between pure liquid and pure vapor. Generally speaking a standard sight glass with an indicator also has a dual function.
It monitors whether the moisture content of the refrigerant is within an acceptable range and it indicates whether liquid refrigerant is always present at the expansion component. If the moisture content is OK the indicator color is green and no further action is necessary. In the installation the sight glasses will not be as quick to change colour when the liquid temperature increases.
This is important to ensure adequate and optimal compressor protection. Danfoss offers sight glasses that are designed for CFC HCFC and HFC refrigerants. Sight glasses for HFC refrigerants Type SGN Give your plant optimal.
Milky color in site glass. I think you are looking at a stained oil sightglass lens from hot oil deposits and the foaming oil behind it caused by low suction superheat or else plus rapid oil return from separator. Recommend a pump down remove and clean oil lense on compressor a oil change with recommended oil.
SGN sight glass is 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. SGN sight glass is equipped with one moisture indicator which wil change color to. High precision color indicator.
Indicator pasted close to the glass to prevent surface contamination. Corrosion resistant brass construction. Clear wide angle visibility.
PTFE seals ensure leak free performance. Applicable for all common HCFC and HFC refrigerants. Color according to the moisture content relative satura-tion in the refrigerant.
A dark green color indicates the refrigerant is DRY and yellow indicates a WET condition. The indicator is formulated so that it changes color at the moisture levels generally accepted as the safe operating range. Single indicator for all common refrigerants.
Accurate color calibration at low ppm levels and higher temperatures. Wide angle viewing high visibility window for ease of monitoring. All brass corrosion resistant body.
Locate a Distributor Near You. Choice of sight glass Before choosing a sight glass with moisture indicator the following should be considered. Type of refrigerant water solubility of refrigerant the level on which a danger signal is required.
Be aware that polyester oil for HFC refrigerants. SADDLE MOUNT SIGHT GLASS 52 mm or 102 mm 2 or 4 STANDARD SIGHT GLASS Purpose. The Refrigerating Specialties liquid level sight glass SG1 provides a clear indication of liquid levels in industrial and commercial refrigeration sys-tems.
