HVAC Sight Glass Moisture Indicator，Compressor Oil Level Indicator SGI / SGRI /SGN / SGRN series

HVAC Sight Glass Moisture Indicator,Compressor Oil Level Indicator SGI / SGRI /SGN / SGRN series

The sight glass is used to indicate:
1. Refrigerant status of refrigerant in the liquid line
2. The water content in the refrigerant
3. Flow condition of the lubricating oil in the return line from the oil separator
4. SG1 / N / H and SGR1 / N / H sight glasses with an indicator, by changing the color to indicate the refrigerant in the water content

Product Features:
1. For HFC refrigerants
2. Indicate excessive water content in the refrigeration system
3. No indication of supercooling of refrigerant liquid
4. Insufficient refrigerant charge indicator
5. Bell, welding, plug-in

Technical Parameters:
Ambient temperature: -50 ℃ ~ +80 ℃
Maximum working pressure:
SG PS / MWP = 35 bar
SG1 / SGN PS / MWP = 35 bar
SGR / SGR1 / SGRN PS / MWP = 35 bar
SGH6, 6s-22s PS / MWP = 46 bar

• The SGI, SGN, SGR, SGRI or SGRN can be used for CFC, HCFC and HFC refrigerants

• The SGI and SGN are fitted with an indicator which changes colour to show the moisture content in the refrigerant.

• The SGR is used to indicate the liquid level in a receiver or the oil level in a compressor crankcase.

• The SGRN and SGRI is a sight glass like SGR, but supplied with a moisture indicator.

• The moisture indicator in the sight glasses are dirt repelling.
