Danfoss TGE Thermostatic Expansion Valve | R410A | 067N3003

Product Description: The 067N3003 is engineered for the high-pressure demands of R410A refrigeration. In the UAE’s intensive cooling market, this valve is a reliable choice for rooftop units and water chillers in Dubai and Abu Dhabi. Its balanced port design is a critical feature, ensuring that the valve maintains stable superheat control even when condensing pressures fluctuate significantly due to the extreme Middle Eastern summer heat. The hermetic, all-laser-welded construction eliminates potential leak paths, providing a robust and maintenance-free solution for high-vibration commercial installations.

Key Features & Benefits:

• Optimized for R410A: Specifically calibrated for the high-pressure properties of R410A, the standard for modern UAE commercial HVAC.
• Balanced Port Technology: Guarantees stable and consistent refrigerant flow despite the wide fluctuations in ambient temperature found in the UAE.
• Leak-Proof Hermetic Build: Laser-welded stainless steel and copper design significantly reduces the risk of refrigerant loss in UAE facilities.
• Corrosion Resistance: Features a stainless steel power element to withstand the humid and saline coastal air of the UAE.
• Bi-metal Solder Connections: Simplifies the brazing process, allowing for direct installation in UAE mechanical rooms without damaging internal valve parts.

FAQs:

• Q: Is the 067N3003 suitable for high-ambient rooftop units in Dubai?
• A: Yes, the TGE series is the industry benchmark for high-ambient reliability and vibration resistance in the UAE.
• Q: Why is the “Balanced Port” important for Sharjah installations?
• A: It prevents the valve from “hunting” (unstable operation) when the outdoor temperature varies, ensuring consistent cooling performance for the building.
• Q: Does this valve require regular maintenance in the UAE?
• A: Due to its hermetic, all-welded design, it is essentially maintenance-free. If it fails, the entire unit should be replaced to maintain system integrity.
