Danfoss TE 20 Thermostatic Element | for R404A / R507A | External Equalization
Product Description:
The Danfoss TE 20 (067B3354) is the essential control component for high-capacity refrigeration systems. Specifically calibrated for R404A and R507A, this element is built to handle the demanding requirements of industrial cold storage and large commercial cooling plants across the UAE. It features a laser-welded stainless steel power element that provides superior strength and longevity, even when exposed to the high-ambient temperatures and vibrations common in Dubai’s industrial sectors. With its external equalization design, the 067B3354 ensures accurate refrigerant metering, protecting large-scale compressor investments and maintaining optimal energy efficiency throughout the cooling cycle.
Key Features & Benefits:
- Industrial-Grade Reliability: Designed specifically for the TE 20 series to manage high refrigerant mass flows in UAE industrial projects.
- Laser-Welded Power Element: Stainless steel construction offers maximum durability and resistance to pressure fluctuations.
- Accurate Superheat Sensing: Optimized for R404A/R507A to prevent liquid slugging and maximize evaporator performance.
- Serviceable Design: The element can be easily replaced on the valve body, reducing downtime and maintenance costs in Dubai’s busy facilities.
- Wide Operating Range: Engineered to perform consistently in the Middle East’s challenging environmental conditions.

FAQs:
- Q: Is the valve body or orifice included in this code?
- A: No, the 067B3354 is the thermostatic element (the top control part) only. The TE 20 body and orifice must be ordered separately.
- Q: Why use external equalization for this element in Dubai?
- A: In large systems common in the UAE, there is often a significant pressure drop across the evaporator. External equalization ensures the valve senses the correct pressure for accurate control.
- Q: Can this be used for R134a?
- A: No, this element is specifically charged for R404A/R507A. Using it with other refrigerants will lead to system inefficiency or failure.
