Introduction:
Sight Glass used cold extrusion to increase the intensity of explosion-proof, with the clear and safe observation window.Sight Glass is uesd to liquid line of refrigerant and air conditioning device,to indicate the flow situation of the refrigerant,the moisture content in the refrigerant,and the flow in the oil return line from the oil separator.
It is fitted with a moisture indicator,which changes color to show the moisture content in the refrigerant. Sight Glass is using modified PTFE sealing materials,and applicable to a variety of refrigerant and POE oil, with perfect sealing performance.
Feature:
1.Indicate over-high water contents in the refrigeration system
2.Indication of refrigerant deficiency
3.Flare or solder connection
4.Compatible with all HCFC and HFC refrigerants and oils
Technical Performance :
Max. working pressure: 3.5MPa
Max. proof pressure: 5.2MPa
Working temperature range: -40℃~+80℃
100% leakage testing

Note: the hermetic compressor allows moisture content between 30~75 PPM commonly,while other compressor is slightly high.In order to make the system get effective protection, must monitor indicator carefully, if the color is yellow, the dryer must be replaced.
