Danfoss TGE Thermostatic Expansion Valve | R410A & R32 | 067N3156

Product Description: The TGE series is engineered to meet the rigorous demands of modern air conditioning and chiller systems. In the UAE’s intensive cooling market, the 067N3156 is a critical component for ensuring precise refrigerant flow. Its hermetic construction features an all-laser-welded design, which minimizes the risk of leaks—a vital factor given the high operating pressures of R410A and R32. This model includes a balanced port, which provides consistent superheat control even when head pressures fluctuate during the extreme heat of a Dubai summer. Its stainless steel power element ensures longevity and resistance to the corrosive environments often found in Middle Eastern industrial zones.

Key Features & Benefits:

• Dual Refrigerant Compatibility: Fully optimized for R410A and the low-GWP refrigerant R32, making it a future-ready solution for UAE’s green building standards.
• Balanced Port Technology: Guarantees stable performance across a wide range of condensing pressures, ideal for the UAE’s high-ambient climate.
• Hermetic, Leak-Proof Design: Laser-welded copper and stainless steel construction eliminates potential leak paths, ensuring maximum system integrity in Dubai.
• High-Pressure Reliability: Specifically built to handle the mechanical and thermal stresses of modern high-pressure cooling systems in the UAE.
• Bi-metal Solder Connections: Enables easier, safer, and more reliable brazing during installation in UAE mechanical rooms.

FAQs:

• Q: Can the 067N3156 be used in R32 residential AC units in the UAE?
• A: Yes, it is specifically rated for R32, which is increasingly common in new, high-efficiency AC installations across the UAE.
• Q: Why is the “Balanced Port” feature important for Abu Dhabi installations?
• A: It prevents the expansion valve from “hunting” or becoming unstable when outdoor temperatures—and thus condensing pressures—are extremely high.
• Q: Does this valve require regular maintenance in Dubai?
• A: Due to its hermetic, all-welded design, this valve is essentially maintenance-free. If it fails, the entire unit is replaced to ensure a leak-proof system.
