Product details

Danfoss TE 2 Thermostatic Expansion Valve | R404A / R507A | External Equalization | 068Z3404

Product Description: The Danfoss TE 2 (068Z3404) is specifically engineered for low and medium-temperature applications, such as walk-in freezers and supermarket cold cases throughout the UAE. By using external equalization, this valve provides highly accurate refrigerant dosing even in systems with high pressure drops across the evaporator. Its modular design, a hallmark of the T2/TE2 series, allows for easy replacement of the orifice assembly, making maintenance in Dubai’s busy commercial sectors both fast and cost-effective. Built with a laser-welded stainless steel power element, it offers exceptional durability and stable performance under the intense thermal demands of the Middle East.

Key Features & Benefits:

  • External Equalization (1/4 in Flare): Delivers precise superheat management by compensating for pressure drops, crucial for large UAE evaporators.
  • Optimized for R404A/R507A: Specifically charged for the thermal characteristics of common commercial refrigerants used in Dubai.
  • Interchangeable Orifice System: Allows for versatile capacity matching and simplified internal cleaning (orifice sold separately).
  • Robust Construction: Features a stainless steel bulb and capillary for superior corrosion resistance and longevity.
  • Compressor Protection: Effectively prevents liquid slugging, extending the life of expensive cooling equipment in the UAE.
