Danfoss TE 20 Thermostatic Power Element | R134a | 067B3292

Product Description: The 067B3292 serves as the sensing and control heart of the TE 20 expansion valve. In the UAE’s high-ambient environment, where R134a is commonly used in medium-temperature refrigeration and large chillers, this element ensures the evaporator receives the correct refrigerant flow. Its stainless steel construction is designed to resist the corrosive humidity found in coastal cities like Dubai and Abu Dhabi. By utilizing a replaceable element design, UAE maintenance teams can restore system efficiency by swapping the element without the need to cut and re-braze the large TE 20 valve body, significantly reducing downtime and labor costs.

Key Features & Benefits:

• Optimized for R134a: Specifically charged to match the pressure-temperature characteristics of R134a, ensuring peak performance in UAE cooling plants.
• Rugged Stainless Steel Build: Offers superior durability and corrosion resistance, essential for the demanding environmental conditions of the Middle East.
• Rapid Repair Solution: The modular design allows for the power element to be replaced while the valve body remains in the system, a major advantage for UAE facility managers.
• Hermetic Integrity: Features a laser-welded diaphragm to prevent charge loss and ensure long-term calibration stability under the UAE’s intense heat.
• Precision Sensing: Equipped with a high-quality capillary tube and bulb for sensitive and accurate superheat regulation.

FAQs:

• Q: Is the 067B3292 compatible with other refrigerants besides R134a?
• A: This specific code is calibrated for R134a. For other refrigerants like R22 or R404A, a different TE 20 element must be selected to ensure proper superheat control in UAE systems.
• Q: Why is R134a still widely used in Dubai commercial projects?
• A: R134a is highly stable and operates at lower pressures, making it excellent for large chillers and medium-temperature applications in the UAE’s high-ambient climate.
• Q: How can I tell if my TE 20 element needs replacing?
• A: If the valve is no longer responding to superheat adjustments or if the system is constantly hunting or “flood back” is occurring, the element (067B3292) may have lost its thermostatic charge.
