Danfoss TE 12 Thermostatic Element | for R22 / R407C | External Equalization

4Product Description:

The Danfoss TE 12 (067B3227) is the control head for mid-to-high capacity expansion valves, specifically calibrated for the pressure-temperature characteristics of R22 and R407C. In the UAE, where these refrigerants are extensively used in rooftop units, medium-sized chillers, and large cold storage evaporators, this element ensures accurate refrigerant metering. Built with a laser-welded stainless steel power element, it offers superior resistance to mechanical fatigue and the extreme ambient heat of Dubai. Its external equalization design allows it to compensate for pressure drops within the evaporator, ensuring that the system operates at peak efficiency while protecting the compressor from liquid return.

Key Features & Benefits:

• Versatile Refrigerant Support: Optimized for both R22 and R407C, perfect for servicing existing installations or R407C retrofits in the UAE.
• Laser-Welded Reliability: Stainless steel construction provides a durable, leak-proof design suitable for harsh Middle Eastern environments.
• Precise Superheat Regulation: Maintains stable cooling performance and maximizes energy efficiency in high-load conditions.
• Serviceable Design: The element can be replaced without removing the valve body, minimizing downtime for critical systems in Dubai.
• Flexible Installation: Equipped with a 3.0-meter capillary tube for convenient bulb placement on larger suction lines.

FAQs:

• Q: Is the 067B3227 element compatible with a TE 5 body?
• A: No, this element is specifically designed for the TE 12 series body and will not fit the smaller TE 5 or larger TE 20 bodies.
• Q: Does this element include the orifice assembly?
• A: No, the 067B3227 is the thermostatic element only. The valve body and orifice must be selected separately based on your required capacity in the UAE.
• Q: Why is external equalization used for TE 12 in Dubai?
• A: Given the higher capacity of TE 12 systems, external equalization is necessary to accurately sense the pressure at the evaporator outlet, ensuring precise superheat control.
