"The rapid growth of AI infrastructure, electrification and energy-efficient HVAC systems is driving demand for more intelligent and efficient thermal management solutions," said Patrick Ku, Head of the Power Electronics Business, Delta Electronics EMEA region. "Our latest EC Fan and innovative EC and HVDC Pump portfolios help customers reduce energy consumption, simplify system integration and prepare for the next generation of cooling applications."
Evolution Driven by the Core: Delta’s New Motor Technology Shapes Ultra-Efficient Cooling for EC Fans
Delta’s latest motor combines efficiency beyond the IE6-equivalent benchmark (20% lower losses than the IE5), IP66-rated protection, and smart control and monitoring for high-airflow EC axial fans and high-pressure EC blowers. Its fully enclosed inner-rotor design is nearly 30% more compact than its predecessor, reducing installation space while optimizing airflow and enhancing overall system efficiency.
Enhanced surge protection and full-load operation at ambient temperatures up to 70°C support reliable performance in demanding environments. Optional Bluetooth & vibration sensor control enables wireless monitoring and parameter adjustment, while a built-in LED status indicator simplifies fault identification to minimize downtime.
ErP 2026-Compliant EC Fan Solutions Deliver Efficiency, Reliability, and Intelligent Control
Beyond these motor enhancements, Delta’s EC fans comply with ErP 2026 ecodesign requirements, supporting energy-efficient chillers, dry coolers, and air-handling units. Depending on the model, they also support full-load operation at ambient temperatures up to 70°C. Selected models maintain total harmonic current distortion (THDi) below 5%, minimizing electrical harmonics and preserving power quality in data centre fan walls and other multi-fan systems. Optional diffusers and flow grids enhance axial fan performance, with diffusers improving efficiency by approximately 8–10% and reducing noise by 2–3 dBA at the same operating point.
Innovative HVDC Pump and Fully Integrated EC Pump Technology
Building on its liquid-cooling experience since 2016, Delta introduces two market-first innovations at Chillventa: an HVDC pump and fully integrated EC pumps with built-in power conversion and motor control. The HVDC pump supports CDU coolant circulation in next-generation AI infrastructure adopting HVDC power architectures. The compact EC pumps eliminate external motor controllers and reduce cabling, while weighing up to 30% less than comparable market offerings, simplifying integration into space-constrained systems such as in-rack and in-row CDUs.
The broader portfolio also includes 48VDC configurations. Depending on the models, features include BLDC motor efficiency exceeding 85%, low-noise and low-vibration operation, IPX6 protection, and an operating temperature range of −10°C to up to 85°C, supporting reliable performance in demanding environments.
Delta welcomes visitors to Hall 7A, Booth 110, from 13 to 15 October, to experience its latest EC fan and liquid-cooling technologies and discuss thermal management solutions with its experts. For details and meetings with Delta’s experts, please visit Delta at Chillventa 2026.
