Danfoss ETS 12C Colibri® Electric Expansion Valve | 1/2 x 1/2 in

Product Description:

The Danfoss ETS 12C Colibri® (034G7502) represents the next generation of EEV technology, featuring an innovative integrated design where the stepper motor and valve body are one hermetic unit. With its balanced cage and linear positioning design, it provides ultra-precise refrigerant flow control even under varying load conditions common in the UAE. The “Colibri” series is known for its extremely fast opening and closing times, which significantly improves system stability and protects the compressor from liquid slugging. Its compact, bi-metal construction allows for easy soldering and installation in tight spaces, making it a favorite for high-efficiency rooftop units, chillers, and heat pumps in Dubai’s premier sustainable building projects.

Key Features & Benefits:

• Ultra-Fast Response: Rapid stepper motor movement ensures stable superheat control even during sudden load changes in the UAE.
• Hermetic Integrated Design: No risk of external leaks through a motor gasket, ensuring long-term reliability in Dubai’s harsh environments.
• Bi-metal Connectors: Allows for fast, easy, and safe brazing without the need for wet-wrapping, saving time for UAE installers.
• Precise Flow Control: Linear flow characteristic provides high resolution at low loads while maintaining high capacity when needed.
• Wide Refrigerant Compatibility: Fully optimized for R410A, R407C, R134a, and the latest low-GWP HFO blends used in the UAE.

FAQs:

• Q: Why is the Colibri ETS 12C better for energy saving in Dubai?
• A: Its precise control allows the system to operate at lower condensing pressures, which significantly reduces the compressor’s energy consumption in the UAE.
• Q: Does it require a special controller in the UAE?
• A: It works perfectly with Danfoss EKE or EKD series controllers, or any standard third-party stepper motor controller used in Dubai.
• Q: Can the ETS 12C handle high-pressure R410A systems?
• A: Yes, with a maximum working pressure of 50 bar, it is specifically designed for high-pressure refrigerants common in UAE air conditioning.
