Product details
Danfoss TGE Thermostatic Expansion Valve | R22 & R407C | 067N2307
Product Description: The 067N2307 is engineered for the highest flow requirements, featuring massive 1-3/8 inch inlet and 1-5/8 inch outlet connections. In the UAE’s intensive cooling sector—such as large-tonnage water chillers in Dubai or industrial process cooling in Abu Dhabi—this valve provides critical superheat control. Its balanced port design is a vital feature for Middle Eastern operations, ensuring that the valve remains stable even when outdoor temperatures cause extreme fluctuations in head pressure. The hermetic, all-laser-welded construction provides maximum protection against refrigerant leaks, which is essential for maintaining the efficiency and environmental compliance of high-capacity UAE cooling plants.
Key Features & Benefits:
- Maximum Mass Flow Capacity: Tailored for the largest cooling loads found in UAE industrial-grade evaporators and central cooling systems.
- Balanced Port Precision: Eliminates the influence of fluctuating condensing pressures, ensuring stable and precise superheat control during the peak UAE summer heat.
- Leak-Proof Reliability: The all-welded hermetic design eliminates gaskets and mechanical joints, providing a robust solution for high-vibration UAE industrial zones.
- Dual Refrigerant Support: Optimized for both R22 and R407C, offering a versatile solution for maintenance and retrofitting in the UAE.
- High-Ambient Durability: Designed to maintain accurate calibration and reliable performance in ambient temperatures up to 70°C.
