Danfoss TE 2 Thermostatic Expansion Valve | R22 / R407C | External Equalization

Product Description:

The Danfoss TE 2 (068Z3211) is a highly adaptable expansion valve, making it a “must-have” for maintenance professionals in the UAE. Specifically charged for compatibility with both R22 and R407C, it provides stable superheat control across a wide range of operating conditions. Its modular design features an interchangeable orifice system, allowing for easy capacity adjustment and simplified on-site repairs in Dubai’s commercial and residential air conditioning units. Built with a laser-welded stainless steel power element, the 068Z3211 is engineered to withstand the thermal stress and high-ambient temperatures common in the Middle East, ensuring long-term system reliability and compressor protection.

Key Features & Benefits:

• Dual Refrigerant Capability: Optimized for both R22 and R407C, providing flexibility for retrofit and repair projects in the UAE.
• Precise Superheat Control: Maintains optimal evaporator efficiency while preventing liquid floodback to the compressor.
• Interchangeable Orifice: Allows for quick capacity matching and easy internal cleaning without replacing the entire valve.
• External Equalization: Features a 1/4 inch flare equalization port to maintain accuracy in systems with significant pressure drops.
• Stainless Steel Durability: High-quality power element offers superior resistance to vibration and corrosion in humid Dubai environments.
