Heat Controller Sight Glasses

Overview

The HEATCONTROLLERDANFOSS014L0173 DANFOSS-014L0173 is a 1/2-inch flare-connection sight glass designed for use in refrigeration and HVAC systems. Sight glasses are installed in liquid lines to give technicians a visual indication of refrigerant flow and condition, allowing them to quickly identify low charge, moisture presence, or vapor bubbles. The SGP 12 N designation indicates a standard sight glass with a moisture indicator window. This component is installed by licensed HVAC and refrigeration technicians during system commissioning, service, or component replacement. This sight glass is suited for residential and light commercial refrigeration and air conditioning systems where a 1/2-inch flare liquid-line connection is required. It is typically installed downstream of the filter-drier and upstream of the metering device, giving the technician a direct view of refrigerant state before the expansion device. The moisture indicator provides a color-change signal when moisture levels in the system exceed acceptable limits, prompting further service.
