Product details
Danfoss ETS 250 Electric Expansion Valve | High-Capacity Precision | 034G2601
Product Description: The ETS 250 (034G2601) is engineered to manage significant cooling loads with extreme accuracy. In the UAE—where systems like large chillers and industrial evaporators must maintain peak efficiency in extreme heat—the ETS 250 uses a bipolar stepper motor to deliver fine-tuned refrigerant injection. This model features a balanced orifice, which not only allows for bi-flow operation (ideal for heat pump systems) but also ensures stable performance even at high pressure differentials. Its integrated sight glass allows technicians in Dubai and Abu Dhabi to monitor the refrigerant’s state and moisture levels directly at the valve.
Key Features & Benefits:
- Precise Stepper Motor Control: Features 3810 steps, providing granular control over the valve opening to optimize superheat and energy consumption.
- Large Capacity Design: Optimized for large-tonnage systems, ensuring consistent cooling performance for massive UAE infrastructure projects.
- Integrated Sight Glass: Includes a moisture indicator for real-time visual inspection of the refrigerant, simplifying troubleshooting for maintenance teams.
- Bi-flow Capability: Delivers high performance in both flow directions, offering flexibility for complex refrigeration circuits.
- Corrosion Resistant: Built with high-grade materials to withstand the humidity and saline conditions typical of the Middle Eastern coastal regions.
