Sporlan 700416 SA-15S Indicator

For veteran technicians managing large-scale refrigeration systems, the Sporlan 700416 SA-15S serves as the industry standard for real-time monitoring of refrigerant conditions. This 5/8" ODF solder moisture liquid indicator is engineered for high-pressure applications, featuring a flared-style sight glass that provides full visibility of the flow. The See-All moisture indicator element utilizes a highly sensitive chemically treated paper that changes color to signal the precise moisture level within the system, allowing for proactive maintenance before acid formation damages the compressor. Designed with a forged brass body and extended copper connections, this unit facilitates a clean brazing process without the risk of damaging internal components. Compatibility includes all common CFC, HCFC, and HFC refrigerants, such as R-410A and R-404A. This indicator is functionally identical to the Sporlan SA-15S, ensuring a direct drop-in replacement for existing liquid line assemblies requiring a 5/8 inch sweat connection.

• Universal Refrigerant Compatibility: Reliable performance with high-pressure HFCs and traditional mineral oil or POE-based lubricants.
• Enhanced Visibility: Large viewing lens allows for easy detection of bubbles, indicating a low refrigerant charge or flash gas in the liquid line.
• High-Sensitivity Element: The moisture indicator provides distinct color changes to distinguish between "dry," "caution," and "wet" system states.
• Durable Construction: Built with a corrosion-resistant brass body and rated for high safe-working pressures common in commercial HVACR.

Common Technical Questions

What does a color change in the sight glass signify?

The indicator element monitors the moisture content of the refrigerant. A "wet" reading typically indicates that the filter-drier is saturated and requires immediate replacement to prevent copper plating or expansion valve freeze-ups.

Is the SA-15S compatible with R-410A systems?

Yes, the Sporlan SA-15S is rated for the higher pressures associated with R-410A and is compatible with both synthetic and natural oils used in modern HVAC liquid line applications.

How do I ensure a proper seal during installation?

Utilize a wet rag or heat-sink paste on the indicator body during the brazing of the 5/8" ODF sweat connections to protect the internal seals and the moisture-sensitive element from excessive heat.
