Danfoss TE 20 Thermostatic Power Element (MOP) | R134a | 067B3293

Product Description: The 067B3293 acts as the control center for the TE 20 expansion valve. Unlike standard elements, this model includes an MOP (Maximum Operating Pressure) function, which limits the suction pressure to protect the compressor from overloading during start-up or after defrost cycles—a vital feature for the heavy-duty cooling loads found in Dubai and Abu Dhabi. Built from high-grade stainless steel, it is engineered to resist the UAE’s corrosive coastal air and extreme ambient temperatures. The modular design of the TE 20 series allows UAE maintenance teams to swap this element without de-brazing the valve body, significantly reducing system downtime.

Key Features & Benefits:

• Compressor Protection (MOP): Features an integrated MOP charge to prevent high suction pressure from damaging the compressor in high-ambient UAE conditions.
• Calibrated for R134a: Specifically designed to match the thermodynamic properties of R134a, a staple refrigerant for UAE chillers and medium-temp storage.
• Rugged Stainless Steel Build: Offers superior durability and corrosion resistance, essential for the demanding environmental conditions of the Middle East.
• Modular Maintenance: The power element can be replaced while the valve body remains in the piping, offering a cost-effective repair solution for UAE facility managers.
• Laser-Welded Integrity: The hermetically sealed diaphragm ensures long-term calibration stability and prevents charge loss under intense thermal cycling.

FAQs:

• Q: Why would I choose the 067B3293 with MOP over a standard element?
• A: In the UAE, systems often face high suction pressures after a shutdown or defrost; the MOP feature in the 067B3293 acts as a safety limit to prevent compressor motor burnout.
• Q: Is this element suitable for R134a chillers in Dubai?
• A: Yes, it is ideal for large commercial chillers and refrigeration systems where R134a is the primary refrigerant.
• Q: Can I replace a non-MOP element with this 067B3293 model?
• A: Yes, as long as it is for a TE 20 valve body and the system requires the added suction pressure protection provided by the MOP charge.
