Delta has unveiled a next-generation EC fan motor, expanded EC fan portfolio and new HVDC and EC electric pumps for HVAC, data centre and industrial applications at Chillventa 2026 in Nuremberg. The technology range is designed to improve energy efficiency, simplify integration and support cooling requirements in buildings, industrial facilities and AI data centres. Delta’s new motor exceeds the IE6-equivalent benchmark, with 20% lower losses than IE5, while its integrated EC pumps can weigh up to 30% less than comparable market offerings. The launch brings together air and liquid-cooling equipment for applications where space, power quality and operational reliability are central considerations.
A Compact Motor Platform
At the centre of Delta’s EC fan range is a fully enclosed inner-rotor motor designed for high-airflow axial fans and high-pressure blowers. The new design is nearly 30% more compact than its predecessor, reducing the space required for installation while supporting airflow and system efficiency. IP66-rated protection, enhanced surge protection and full-load operation at ambient temperatures up to 70°C are intended for demanding cooling environments.
Smart control and monitoring functions form part of the motor platform. Optional Bluetooth and vibration-sensor control allow wireless monitoring and parameter adjustment, while a built-in LED status indicator is designed to make fault identification faster for maintenance teams.
Patrick Ku, Head of the Power Electronics Business, Delta Electronics EMEA region, said:
“The rapid growth of AI infrastructure, electrification and energy-efficient HVAC systems is driving demand for more intelligent and efficient thermal management solutions.”
Fans For Efficient Cooling
Delta’s EC fans comply with ErP 2026 ecodesign requirements and are aimed at energy-efficient chillers, dry coolers and air-handling units. Depending on the model, the fans can operate at full load in ambient temperatures of up to 70°C, extending their suitability for installations where thermal conditions are particularly demanding.
Selected models maintain total harmonic current distortion below 5%. This can help preserve power quality in data centre fan walls and other multi-fan systems, where multiple units operate together. Delta is also offering optional diffusers and flow grids for axial fans. According to the company, diffusers can improve efficiency by approximately 8% to 10% and reduce noise by 2 to 3 dBA at the same operating point.
The combination of compact motor design, monitoring capability and fan-system options gives cooling-system designers a broader set of choices for balancing airflow, space and electrical performance. It is particularly relevant as data centre infrastructure requires more tightly managed thermal systems alongside wider electrification across buildings and industry.
Patrick Ku, Head of the Power Electronics Business, Delta Electronics EMEA region, said:
“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.”
Liquid Cooling Pump Range
Delta has also introduced an HVDC pump and fully integrated EC pumps, drawing on its liquid-cooling experience since 2016. The HVDC pump supports coolant circulation in coolant distribution units for AI infrastructure using HVDC power architectures. This places the product within a cooling segment where power delivery and liquid circulation must work closely together.
The fully integrated EC pumps combine power conversion and motor control within the pump itself. By eliminating external motor controllers and reducing cabling, the products are intended to simplify installation in space-constrained systems, including in-rack and in-row coolant distribution units. The compact pumps weigh up to 30% less than comparable market offerings.
The broader range includes 48VDC configurations. Depending on the model, features include BLDC motor efficiency exceeding 85%, low-noise and low-vibration operation, IPX6 protection and an operating temperature range from −10°C to up to 85°C. These specifications support deployment across cooling applications with different environmental and integration requirements.
Cooling For Changing Infrastructure
Delta’s Chillventa 2026 presentation brings its fan, motor and pump technologies into one thermal-management portfolio. The range addresses air cooling and liquid cooling requirements through products designed around efficiency, compact integration and monitoring. For operators of HVAC equipment, industrial systems and data centres, the launch offers equipment choices that reflect the increasing cooling demands associated with AI infrastructure and electrification.
Visitors can see the technology at Delta’s stand in Hall 7A, Booth 110, from 13 to 15 October. The presentation offers a focused view of how EC motor technology, fan design and integrated pumping systems can contribute to lower-energy cooling installations.
