Product details
Danfoss TGE Thermostatic Expansion Valve | R134a & R513A | 067N5009
Product Description: The TGE series is engineered to provide reliable and precise superheat control for medium-to-high capacity systems. In the UAE’s intensive climate, the 067N5009 is a preferred choice for water chillers, transport refrigeration, and large commercial AC units in Dubai and Abu Dhabi. Its hermetic design eliminates the need for gaskets, significantly reducing the risk of refrigerant leaks—a critical factor for long-term operational efficiency. This model features a balanced port design, ensuring stable performance despite the fluctuating head pressures common during the extreme UAE summer. It is also compatible with R513A, making it an excellent choice for modern, lower-GWP (Global Warming Potential) retrofits and new installations.
Key Features & Benefits:
- Dual Refrigerant Compatibility: Optimized for R134a and its lower-GWP alternative R513A, meeting modern UAE environmental standards.
- Balanced Port Technology: Provides consistent flow regulation regardless of condensing pressure variations, ideal for the high-ambient conditions of the Middle East.
- Leak-Proof Hermetic Design: Laser-welded construction ensures maximum system integrity and reduces maintenance costs in UAE facilities.
- High Durability: Specifically built to handle the rigorous duty cycles of commercial refrigeration and industrial cooling in Dubai.
- Stable Superheat Control: Enhances evaporator efficiency, leading to lower energy consumption for UAE building owners.

FAQs:
- Q: Is the 067N5009 suitable for retrofitting older R134a systems in the UAE?
- A: Yes, it is a perfect drop-in replacement for R134a systems and is fully compatible with R513A if the system is being upgraded to a more eco-friendly refrigerant.
- Q: Why is the “Balanced Port” design vital for Abu Dhabi summers?
- A: During extreme heat, head pressures rise significantly; the balanced port prevents the valve from losing control, ensuring the cooling output remains stable.
- Q: Can this valve be used in transport refrigeration in Dubai?
- A: Yes, the TGE series is robust and vibration-resistant, making it highly suitable for refrigerated trucks and containers operating in the UAE.
