Product details
Danfoss TGE Thermostatic Expansion Valve | R22 & R407C | 067N2011
Product Description: The 067N2011 is designed to excel in the UAE’s demanding high-ambient conditions. In the Middle Eastern market, where equipment must withstand intense thermal loads, this valve’s balanced port design is a critical advantage. It ensures that the valve’s performance remains consistent even when condensing pressures fluctuate significantly due to the extreme Dubai summer heat. The hermetic, all-laser-welded construction eliminates potential leak paths, providing a maintenance-free and environmentally secure solution for high-vibration commercial installations. Its stainless steel power element ensures longevity and resistance to the corrosive, saline air found in UAE coastal regions.
Key Features & Benefits:
- Dual Refrigerant Compatibility: Optimized for both R22 (for maintaining existing UAE systems) and R407C (for modern installations).
- Balanced Port Performance: Guarantees stable and precise superheat control despite the wide variations in head pressure common in the UAE.
- Leak-Proof Hermetic Design: Laser-welded construction ensures maximum system integrity and reduces refrigerant recharge costs for UAE facility managers.
- High Durability: Specifically built to handle the rigorous duty cycles and thermal stresses of Middle Eastern commercial cooling.
- Bi-metal Solder Connections: Simplifies the brazing process for UAE technicians, allowing for a secure installation without risking damage to internal components.

FAQs:
- Q: Is the 067N2011 suitable for large rooftop units in Dubai?
- A: Yes, the TGE series is the industry standard for high-ambient reliability and is widely used in rooftop AC and chiller units throughout the UAE.
- Q: Why is the “Balanced Port” important for Sharjah installations?
- A: It prevents the valve from “hunting” when outdoor temperatures vary, ensuring consistent cooling performance and protecting the compressor from liquid slugging.
- Q: Does this valve require regular maintenance in the UAE?
- A: No. Due to its hermetic, all-welded design, this valve is essentially maintenance-free. If it fails, the entire unit is replaced to maintain system integrity.
