The frost-proof sight glass is used in refrigeration equipment operating below -20°C, effectively preventing frost formation on its surface through the principle of isolation with transparent acrylic glass.
Sight glass without dryness and humidity indication is installed in the oil pipeline to clearly observe the flow state of refrigeration oil; sight glass with dryness and humidity indication is installed in the refrigerant pipeline to provide real-time early warning on the water content of the refrigerant through the color change (green when it is dry and yellow when it is damp), so as to prevent ice blockage, corrosion and other hidden dangers.
CO<sub>2</sub> Sight glasses are divided into compressor oil viewing flange type and threaded type oil viewing glasses; The water content and oil return of the refrigerant are observed in the pressure vessel with a float type sight glass and in the pipeline system. The materials are carbon steel and stainless steel.
