5/8″ SIGHT GLASS – 10.0hp – 15.0hp

Description

– The sight glass ensures a fast and safe inspection of the conditions of the refrigerant fluid. It allows you to determine the state of refrigerant charge, to detect restrictions in the system, to find any presence of moisture, and to detect if the oil return to the compressor crankcase.
– The presence of bubbles indicates that the refrigerant fluid is partial evaporating along the liquid line.
– The sight glass will show bubbles if the system is low on refrigerant. The sight glass may show a few bubbles when the system first starts. Or, they may appear just as the system stops.
– These are normal equalizing actions and do not indicate a shortage of refrigerant. Bubbles may also show a restriction in the circuit ahead of the sight glass. This may be due to a partially clogged drier, screen, or filter.
– The sight glass has long extensions that permit soldering or brazing the joints without injury to the sight glass. Some sight glasses are built into a suction line or liquid line filter-drier.
– Sight glasses also incorporate a visual moisture indicator which changes colour if moisture rises to an unacceptably high level. The moisture/liquid indicators consist of a sensitive element as a ring, which changes colour in the presence of water. The amount of change indicates the amount of water present.
