Sight glasses

Sight glasses

Sight glasses are used to give a clear visual indication of refrigerant condition, flow condition, moisture status, liquid level, or oil level in refrigeration systems. In cold room applications, they help installers and service technicians check system condition directly in the refrigeration circuit and identify issues such as moisture, lack of subcooling, or refrigerant deficiency.
This category is built around high-pressure sight glasses and includes versions with and without moisture indicators, depending on the application's need. Beyond cold rooms, sight glasses are also used in chillers, heat pumps, transport refrigeration, food retail refrigeration, and broader refrigeration and air-conditioning systems.
