373-652 Sightglass with Moisture Indicator Cutaway

DAC Worldwide’s Sightglass with Moisture Indicator Cutaway (373-652) is a professionally-crafted, sectioned example of a specialty sight glass/moisture indicator (HMI) assembly used in air conditioning and refrigeration systems as a diagnostic and system condition monitoring device. Through its combined purpose of checking liquid lines for evidence of vapor, as well as detection of system humidity/moisture content, it ensures long life of many system components and maximum system heat transfer efficiency. When excessive system water is witnessed by an indicator color change, it can lead to expansion valve failure and encourages acid formation.

A full cutaway view of the viewing cavity unveils the mounting position of the tri-colored moisture-sensitive molded disc as well as the full flow path. This economical, sectioned example showcases the device’s operating principle, internal components, and related installation concerns. Multiple cutaways unveil all internal components, which enhances classroom training in HVAC system design, maintenance, troubleshooting, and preventive/predictive maintenance.
