Product details
Danfoss LLG 590 S Sight Glass | Liquid Level Gauge | 2512+058
Product Description: The Danfoss LLG 590 S (2512+058) is an essential monitoring component for industrial refrigeration plants in the UAE. Specifically engineered for use with Ammonia ($NH_3$), HFCs, and HCFCs, this sight glass allows for accurate visual verification of the liquid level within high-pressure receivers and surge drums. Built to withstand the extreme ambient conditions of Dubai, the LLG 590 S features a robust steel construction and specialized safety glass that remains clear and resistant to thermal shock. Its “S” designation indicates a standard length suitable for large industrial vessels common in UAE food processing and cold storage facilities. This gauge is vital for ensuring system efficiency and safety, allowing UAE technicians to monitor oil and refrigerant levels without interrupting plant operations.
Key Features & Benefits:
- Exceptional Visual Clarity: High-quality safety glass ensures a clear view of the liquid level, even in the humid and dusty environments of the UAE.
- Industrial Strength Construction: Designed to handle high-pressure loads and the corrosive atmospheres typical of Dubai’s industrial and coastal zones.
- Broad Refrigerant Compatibility: Optimized for Ammonia ($R717$) systems, the backbone of UAE’s large-scale cooling infrastructure, as well as synthetic refrigerants.
- Safety Focused Design: Built to meet strict international standards, preventing leaks and glass failure under the intense thermal cycles of the Middle East.
- Reliable Level Monitoring: Enables UAE operators to maintain optimal refrigerant charges, preventing equipment damage and ensuring consistent cooling performance.

FAQs:
- Q: Why is the LLG 590 S (2512+058) preferred for Ammonia plants in the UAE?
- A: Its robust materials are specifically chosen to resist the chemical properties of Ammonia, which is widely used in large-scale UAE refrigeration for its efficiency.
- Q: Can this sight glass be used in low-temperature applications in Dubai?
- A: The LLG 590 S is rated down to -10°C. For lower temperature requirements in UAE freezers, specialized low-temperature sight glass variants may be required.
- Q: Does the glass need special cleaning in the UAE environment?
- A: To maintain visibility in the dusty UAE climate, the exterior glass should be wiped periodically with a non-abrasive cleaner to ensure the level remains easily readable.
