Danfoss TGE Thermostatic Expansion Valve | R22 & R407C | 067N2162

Product Description: The 067N2162 is engineered to provide stable performance in the UAE’s demanding high-ambient conditions. Its hermetic construction features an all-laser-welded design, which eliminates gaskets and significantly reduces the risk of refrigerant leaks—a critical factor for systems operating in the high-vibration environments of Dubai and Abu Dhabi. This model includes a balanced port, which ensures that the valve’s opening degree is unaffected by the high condensing pressures common during the peak Middle Eastern summer. With its stainless steel power element and durable brass body, it offers long-term reliability for rooftop units, chillers, and large refrigeration racks.

Key Features & Benefits:

• Dual Refrigerant Compatibility: Optimized for both R22 and R407C, providing a versatile solution for maintenance or retrofitting of UAE cooling systems.
• Balanced Port Technology: Guarantees precise superheat control and stable operation despite the wide fluctuations in head pressure found in the UAE.
• Leak-Proof Hermetic Design: Laser-welded copper and stainless steel construction ensures maximum system integrity and reduces maintenance costs.
• Corrosion Resistance: Built with high-grade materials to withstand the humidity and saline air typical of coastal regions in the UAE.
• Bi-metal Solder Connections: Simplifies the brazing process for UAE technicians, allowing for a secure installation without risking damage to the valve’s internal parts.

FAQs:

• Q: Is the 067N2162 suitable for retrofitting older R22 systems in the UAE?
• A: Yes, it is fully rated for both R22 and R407C, making it an excellent choice for facility managers in Dubai looking to modernize their systems.
• Q: Why is the “Balanced Port” important for Sharjah installations?
• A: It prevents the expansion valve from becoming unstable when outdoor temperatures—and thus condensing pressures—are extremely high.
• Q: Does this valve require regular maintenance in the UAE?
• A: Due to its hermetic, all-welded design, it is essentially maintenance-free. If a failure occurs, the entire unit should be replaced to maintain system security.
