Announcement
SUNON announced on July 29, 2026, from Kaohsiung that it is launching a next‑generation Green EC Fan Series designed to comply with the newly implemented EU ErP 2026 energy‑efficiency standards. The company positions the series under its "Go Green with SUNON Cooling" brand promise, emphasizing maximum airflow, smart telemetry and uncompromising reliability for high‑density computing environments.
Technical Features
The new EC fans integrate Modbus‑RTU communication and PWM speed control, providing real‑time status monitoring and dynamic power allocation compatibility. This enables host systems to adjust fan speeds in response to live thermal loads, thereby eliminating idle power waste. Voltage support is universal, covering single‑phase 200–277VAC and three‑phase 380–480VAC, while the motor technology is engineered for the emerging 800VDC era, targeting AI data centres, high‑performance computing platforms, HVAC, energy‑storage systems and EV‑charging stations.
Certifications & Applications
All models meet IP55 or IP68 ingress‑protection ratings; IP55 variants are suited for highly humid commercial refrigeration, whereas IP68 versions resist salt‑spray corrosion for outdoor energy‑storage and EV‑charging deployments. The series also carries EU ATEX gas‑explosion‑proof certification, featuring spark‑free architecture to mitigate ignition risks in volatile settings. SUNON cites field‑tested applications across petrochemical, pharmaceutical, food‑processing and new‑energy plants, asserting that the fans enable rapid implementation and seamless regulatory compliance.
Design Innovations
Aerodynamic improvements stem from fluid‑dynamics simulations that increased blade curvature and surface area, producing a concentrated airflow profile with extended air‑throw distances. The fans employ SUNON’s proprietary vertical MagLev motor system, which stabilises the rotor’s centre of gravity to eradicate mechanical wobble. High‑temperature‑resistant VAPO sleeve bearings replace traditional sleeve bearings, delivering near‑zero vibration and an extended operational lifespan, particularly beneficial for noise‑sensitive medical and laboratory refrigeration.
Outlook
SUNON states that the Green EC series will continue to evolve under its sustainability philosophy, aiming to help global customers enhance energy efficiency, accelerate low‑carbon transformation and meet stringent ESG mandates as the industry transitions to next‑generation power architectures.
