Description
Copeland HMI-1TT9 Hermetic Moisture Indicator — Model 065411
The Copeland 065411 Hermetic Moisture Indicator (Model HMI-1TT9) is a precision-engineered refrigeration system component designed to give technicians and service professionals a reliable, at-a-glance indication of moisture levels within a refrigerant circuit. Moisture contamination is one of the leading causes of compressor and system failures, making a quality moisture indicator an essential component in any well-maintained refrigeration or air conditioning system.
Key Features
- Model: HMI-1TT9 (SKU: 065411)
- Connection Type: 1-1/8″ Sweat (ODF)
- Maximum Working Pressure: 680 PSI
- Refrigerant Compatibility: CFC, HCFC, and HFC refrigerants
- Hermetic construction for reliable, long-term performance in sealed refrigerant systems
- Color-changing moisture indicator element provides quick visual moisture status
Refrigerant Compatibility
The HMI-1TT9 is engineered for use with a broad range of refrigerants, including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs). This wide compatibility makes it a versatile choice for both legacy systems and modern, environmentally compliant refrigerant applications.
High-Pressure Rated Design
With a maximum working pressure rating of 680 PSI, this moisture indicator is built to handle the demands of high-pressure refrigerant systems. The robust hermetic design ensures integrity under operating pressures common in commercial and industrial refrigeration and HVAC applications.
Easy Installation
The 1-1/8″ sweat (ODF) connection allows for straightforward brazing into the liquid line of the refrigerant circuit. This industry-standard connection type ensures compatibility with common copper tubing used in commercial and residential HVAC/R systems.
Why Use a Moisture Indicator?
Moisture in a refrigerant system can cause acid formation, corrosion, freeze-ups, and compressor damage. Installing a Copeland hermetic moisture indicator allows service technicians to monitor system moisture content during routine maintenance, quickly identifying when a filter drier change or system evacuation may be necessary — protecting equipment and extending system life.
Applications
- Commercial refrigeration systems
- Air conditioning systems
- Heat pump systems
