Danfoss ETS 25C Colibri® Electric Expansion Valve | 5/8 x 5/8 in

Product Description:

The Danfoss ETS 25C Colibri® (034G7602) features an advanced ratiometric stepper motor design that is hermetically sealed within the valve body, eliminating potential leak paths and ensuring long-term reliability. With its 5/8 in x 5/8 in connections, it is the perfect fit for UAE commercial cooling racks and high-efficiency chillers. The Colibri technology allows for an extremely fast full-stroke response, which is essential for protecting compressors during rapid load changes in Dubai’s extreme climate. Its stainless steel and bi-metal construction provides excellent corrosion resistance against saline air, while the linear flow characteristics ensure stable regulation even at low-load conditions, maximizing the overall energy rating of the HVAC system.

Key Features & Benefits:

• Fast Closing/Opening: Responds in seconds to load changes, preventing liquid floodback and improving compressor safety in the UAE.
• Zero Leakage Risk: Fully integrated, hermetic motor-to-body design ensures no refrigerant loss, meeting strict Dubai environmental standards.
• Easy Installation: Bi-metal connectors allow for direct brazing without the need for cooling rags, saving significant labor time for UAE contractors.
• Balanced Cage Design: Provides bi-directional flow capability with consistent performance, ideal for heat pump applications in the Middle East.
• Superior Durability: High-grade materials resist the intense thermal and chemical stresses of modern UAE refrigeration circuits.

FAQs:

• Q: Is the ETS 25C suitable for cooling towers in Dubai?
• A: Yes, its hermetic design and stainless steel components are well-suited for the humid and challenging environments of UAE cooling tower systems.
• Q: Do I need a specific cable for this valve in the UAE?
• A: Yes, it uses the standard M12 4-pin cable (like the 034G7074) for connection to the Danfoss EKE or EKD controller.
• Q: Can I use it as a solenoid valve for positive shut-off?
• A: The ETS 25C provides a very tight shut-off, but for critical safety applications in the UAE, we still recommend a dedicated solenoid valve.
