Danfoss TGE Thermostatic Expansion Valve | R22 & R407C | 067N2159

Product Description: The 067N2159 is built for high-mass flow applications, featuring a large 1-3/8 inch outlet connection. In the UAE’s intensive cooling sector—where large-tonnage water chillers and massive rooftop units are the standard—this valve provides unmatched reliability. Its balanced port design is a critical feature, ensuring that the valve maintains 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 overhead and protecting the system’s refrigerant charge in high-vibration industrial environments.

Key Features & Benefits:

• Industrial-Grade Capacity: Optimized for high-tonnage cooling loads in UAE commercial complexes and industrial refrigeration plants.
• Balanced Port Technology: Guarantees precise flow regulation regardless of condensing pressure variations common in the Middle Eastern climate.
• Leak-Proof Hermetic Design: The 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.
• Thermal Resilience: Specifically designed to maintain accurate calibration and reliable performance in ambient temperatures up to 70°C.
