Danfoss TE 5 Thermostatic Element | for R407C | External Equalization

Product Description:

The Danfoss TE 5 (067B3278) is the dedicated control head for the TE 5 series, specifically charged to match the unique temperature-glide characteristics of R407C. In the UAE, where R407C is commonly used as an eco-friendly replacement for R22 in medium-capacity chillers and DX systems, this element ensures the valve responds accurately to load changes. Built with a laser-welded stainless steel power element, it provides superior resistance to the thermal stress caused by Dubai’s extreme ambient temperatures. Its external equalization design allows for precise refrigerant dosing, protecting the compressor and ensuring the evaporator operates at peak efficiency even during peak summer months.

Key Features & Benefits:

• Specialized R407C Charge: Engineered to handle the specific properties of R407C for stable and accurate control in UAE HVAC systems.
• Laser-Welded Durability: Stainless steel construction guarantees a long, leak-proof service life in demanding Middle Eastern climates.
• Precise Superheat Regulation: Minimizes the risk of liquid return to the compressor, extending the life of high-value equipment.
• Service-Friendly Design: Allows for easy replacement on the TE 5 valve body without the need for unbrazing pipes in your Dubai facility.
• External Equalization: Compensates for pressure drops across the evaporator, ensuring the most accurate superheat sensing.

FAQs:

• Q: Can I use this element on a system that was originally R22?
• A: Yes, if the system has been retrofitted to R407C, this element is the correct choice to ensure the expansion valve operates properly in your UAE installation.
• Q: Is the orifice included in this code?
• A: No, the 067B3278 is the element only. You must select the appropriate orifice for the TE 5 body based on your required cooling capacity.
• Q: Why does it have a 3-meter capillary?
• A: The extra length is provided to allow for optimal bulb placement on suction lines, regardless of the evaporator’s size or configuration in Dubai’s complex HVAC setups.
