Product details
Danfoss TGE Thermostatic Expansion Valve | R22 & R407C | 067N2168
Product Description: The 067N2168 is designed for larger capacity requirements, making it a critical component for large water chillers, rooftop air conditioning units, and industrial refrigeration racks in Dubai and Abu Dhabi. This valve features a balanced port design, which is essential for the UAE’s volatile ambient conditions; it ensures that the valve’s performance remains consistent even when head pressures spike during the peak summer heat. The hermetically sealed, laser-welded stainless steel and copper construction provide a leak-free solution, reducing the environmental impact and refrigerant recharge costs for UAE facility managers.
Key Features & Benefits:
- Extended Capacity Range: Optimized for larger evaporators found in UAE commercial and industrial cooling applications.
- Dual Refrigerant Capability: Fully compatible with R22 and R407C, providing flexibility for maintenance of existing UAE infrastructure and new projects.
- Balanced Port Performance: Eliminates the influence of fluctuating condensing pressures, ensuring stable superheat control throughout the day and night in the Middle East.
- Leak-Proof Reliability: All-welded hermetic design provides maximum system security against refrigerant loss in high-vibration UAE environments.
- Bi-metal Solder Connections: Simplifies the installation process, allowing for direct brazing without the risk of damaging internal components.

FAQs:
- Q: What makes the 067N2168 different from smaller TGE models?
- A: This model features a significantly larger 1-3/8 inch outlet connection, designed to handle the higher mass flow rates of large-scale UAE commercial chillers.
- Q: Can this valve handle the high humidity of coastal Dubai?
- A: Yes, its hermetic construction and high-grade materials are specifically designed to resist corrosion and moisture ingress typical of the UAE coast.
- Q: Is it necessary to insulate the sensing bulb in Abu Dhabi?
- A: Absolutely. For accurate sensing in the high ambient heat of the UAE, the bulb must be securely strapped and well-insulated from the surrounding air.
