Danfoss ETS 400 Electric Expansion Valve | Precision Cooling | 034G3500

Product Description: The ETS 400 (034G3500) utilizes a stepper motor to provide highly accurate refrigerant flow control. In the UAE’s intensive cooling sector—including district cooling plants, data centers, and large commercial chillers—the ETS 400 is favored for its ability to maintain stable superheat even under rapidly changing load conditions. Unlike traditional thermostatic valves, this electric valve works in tandem with an electronic controller (like the Danfoss EKE series) to optimize evaporator performance. Its balanced orifice design ensures bi-flow capability, making it ideal for heat pump systems and complex refrigeration racks common in Dubai and Abu Dhabi.

Key Features & Benefits:

• High-Precision Flow Control: The stepper motor provides a high number of steps (3810 steps), allowing for extremely fine adjustments to refrigerant flow for maximum efficiency.
• Energy Savings: Optimized superheat control reduces compressor energy consumption, a major operational advantage given the high cooling demands in the UAE.
• Bi-flow Capability: Designed to perform equally well in both flow directions, simplifying piping in heat pump and defrosting applications.
• Corrosion-Resistant Construction: Built with high-grade stainless steel internals and a robust brass body to withstand humid and demanding environments.
• Wide Refrigerant Range: Fully compatible with common refrigerants used in the Middle East, including R134a, R404A, R407C, R410A, and R507.

FAQs:

• Q: Can the ETS 400 034G3500 be used in UAE district cooling chillers?
• A: Yes, its high capacity and precision make it an excellent choice for large chillers requiring fine-tuned refrigerant control.
• Q: What controller is recommended for this valve?
• A: It is typically paired with Danfoss EKD or EKE superheat controllers, but it is compatible with most third-party bipolar stepper motor drivers used in the UAE.
• Q: Is the cable included with the valve?
• A: The 034G3500 is usually the valve body with the integrated motor; the electrical M12 cable is often ordered separately depending on the length required for the site.
