Danfoss SGN 22s Sight Glass | 22 mm (7/8 in) ODF Solder
Product Description:
The Danfoss SGN 22s (014-0186) is a fundamental monitoring component for high-capacity cooling plants throughout the UAE. Featuring 22 mm (7/8 in) ODF solder connections, it provides a robust, leak-proof joint that withstands the high thermal expansion and vibration typical of Dubai’s industrial mechanical rooms. The SGN series is specially calibrated for use with HFC refrigerants (like R134a, R404A, and R407C), featuring a high-precision moisture indicator that changes color to warn of water ingress. This allows UAE service engineers to proactively manage system chemistry, preventing acid formation and ensuring the long-term reliability of compressors operating under the Middle East’s intense ambient loads.
Key Features & Benefits:
- Optimized for HFCs: Indicator chemistry is specifically designed for high-accuracy readings with HFC refrigerants common in the UAE.
- High-Flow Visual Port: Large glass area allows for easy observation of the liquid line to detect bubbles or flash gas in Dubai’s HVAC systems.
- Hermetic Solder Connection: 7/8 inch ODF ports ensure a permanent, brazed bond, reducing leak risks in large-scale UAE projects.
- Robust Brass Construction: Engineered to resist the corrosive effects of the humid and saline air found along the UAE coast.
- Wide Temperature Resilience: Maintains accurate readings and structural integrity from -50°C up to +80°C in the UAE climate.

FAQs:
- Q: What is the main difference between SGN (014-0186) and SGP in the UAE?
- A: The SGN series is specifically optimized for HFC refrigerants with a 35 bar rating, while SGP is a universal version (including R410A) with a higher 52 bar rating for UAE systems.
- Q: Can this be used for R410A systems in Dubai?
- A: For R410A, the higher-pressure SGP series (52 bar) is generally recommended in the UAE over the SGN series (35 bar).
- Q: Does the indicator need to be replaced after a moisture event in the UAE?
- A: No, the indicator is reversible. Once the moisture is removed (e.g., after changing the filter drier in your UAE system), it will return to green.
