Product details
Danfoss TGE Thermostatic Expansion Valve | R22 & R407C | 067N2306
Product Description: The 067N2306 represents the upper tier of the TGE family’s capacity range, specifically built to handle high mass flow rates in large-tonnage evaporators. In the UAE’s intensive cooling environment—where systems like district cooling support units and massive industrial chillers operate under extreme thermal stress—this valve provides unmatched reliability. Its balanced port design is critical for maintaining stable superheat control even when head pressures fluctuate significantly due to the peak Dubai summer heat. The hermetic, laser-welded construction ensures a leak-proof operation, reducing maintenance costs and protecting the environmental integrity of large UAE facilities.
Key Features & Benefits:
- Maximum Industrial Capacity: Optimized for high-tonnage cooling loads in UAE industrial plants and large commercial complexes.
- Balanced Port Technology: Guarantees precise flow regulation regardless of condensing pressure spikes common in the Middle Eastern climate.
- Leak-Proof Hermetic Design: All-welded stainless steel and copper build eliminates potential leak paths, ensuring maximum system security in Abu Dhabi.
- Dual Refrigerant Versatility: Fully rated for both R22 and R407C, providing a robust solution for both legacy system maintenance and modern upgrades in the UAE.
- Corrosion Resistant Power Element: High-grade materials ensure the valve maintains calibration despite high humidity and saline coastal air.

FAQs:
- Q: Why are the connections (1-3/8″ x 1-3/8″) symmetric on the 067N2306?
- A: These large, equal-sized connections allow for high-volume refrigerant flow with minimal pressure drop, essential for the high-efficiency requirements of large UAE industrial evaporators.
- Q: Is this valve suitable for high-ambient rooftop installations in Dubai?
- A: Yes, the TGE series is the industry benchmark for high-ambient reliability and vibration resistance in the UAE.
- Q: Can the 067N2306 be used with other refrigerants?
- A: This specific model is calibrated for R22 and R407C. Using it with other gases may lead to inaccurate superheat control in your UAE system.
