Danfoss TGE Thermostatic Expansion Valve | R22 & R407C | 067N2156

Product Description: The 067N2156 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 is the main application for the 067N2156 in the UAE?
• A: It is widely used in large-scale commercial chillers and industrial cooling plants that require high mass flow rates and stable superheat control.
• Q: Why is the “Balanced Port” design essential for Abu Dhabi summers?
• A: During peak heat, head pressures spike; the balanced port prevents the valve from losing control, ensuring the cooling output remains stable for the building.
• Q: Can this valve be used for R22-to-R407C retrofits in the UAE?
• A: Absolutely. It is fully rated for both, making it an ideal choice for UAE facility managers looking to transition to more eco-friendly refrigerants.
