Danfoss Sight Glass

The optimal protection lies in the unique indicator which changes colour to show the moisture content within the refrigerant. Danfoss sight glasses are the less effected by temperature when compared to other brand equivalents and they guarantee the best visual indication of moisture throughout the whole year. With the same moisture content 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.

SGN/H, SGR, SGRN/H: secure optimal protection

Sight glasses are mostly installed in the liquid line between the filter drier and the expansion valve to monitor the condition of the refrigerant. The SGR is mainly used to indicate the condition of the refrigerant as well as the liquid level in the receiver or the oil level in the compressor and has no moisture indicator. The SGN/H and SGRN/H are equipped with sensitive indicators that reflects a colour, depending on the moisture content in the refrigerant.
