The Danfoss SGP sight glass offers optimal visibility and is designed to cover higher pressure applications with a Maximum Working Pressure up to 52 bar.
This means the SGP is also suitable for R410A, R32 & sub critical R744.
SGP sight glasses are fitted with an indicator, which changes colour to show the moisture content in the refrigerant.
The sight glass will also indicate a lack of sub cooling or a shortage of refrigerant in the system.
