Danfoss ETS 400 Electric Expansion Valve | 1 5/8 x 1 5/8 in ODF
Product Description:
The Danfoss ETS 400 (034G3501) is the definitive solution for high-tonnage cooling requirements in the UAE. As the largest valve in the standard ETS range, it utilizes a high-resolution bipolar stepper motor to provide unmatched accuracy in refrigerant dosing, which is vital for maintaining system stability in Dubai’s extreme peak-load scenarios. With its 1 5/8 in solder connections, it is engineered for large-scale evaporators in district cooling plants, massive water-cooled chillers, and industrial processing facilities. The ETS 400 features a balanced orifice design that facilitates bi-flow operation, making it ideal for the Middle East’s most powerful reversible heat pump systems. Its robust, hermetically sealed construction ensures a lifetime of reliable performance under the intense pressure and thermal conditions typical of UAE infrastructure projects.
Key Features & Benefits:
- Ultimate Flow Capacity: Designed for the largest piping systems (1 5/8 in) in UAE industrial HVAC applications.
- Superior Superheat Precision: High-resolution stepper motor ensures stable and efficient evaporator performance, even during rapid load shifts in Dubai.
- Energy Management Excellence: Enables precise modulation that significantly reduces the operating costs of high-tonnage UAE chillers.
- Bi-directional Capability: Delivers peak performance in both flow directions, perfect for large-scale UAE reversible cooling plants.
- Rugged Hermetic Build: Constructed from high-grade stainless steel and copper to resist corrosion in the humid and saline environments of the UAE.
