From  June  3rd  to 5th, 2026, the 25th  GPOWER Shanghai   International  Power Equipment  and  Generator  Set  Expo   was  grandly  opened  at the  Shanghai  New International  Expo  Center. Zhejiang  Mingzhen  Electronics  participated  in  the exhibition with its full range of AC/EC high-end  cooling fans. Relying  on  three decades of European export technology accumulation, its  full  range   of  products comply  with  the  EU  ErP2026  energy  efficiency  standards. Focusing  on   core scenarios  such  as  power  equipment  cooling, energy  storage  cabin  temperature control,  energy   storage  air  conditioning, and   data   center   cooling, it   brings   a one-stop efficient, energy-saving, and  intelligent ventilation and cooling  solution,  helping the  industry achieve green and low-carbon upgrades  through  dual  lines.

Special   cooling   solution   for   power   equipment

 

AC900 internal rotor axial fan (suitable for high-power gas generator sets, heavy-duty power equipment, and large machine room cooling)

EC990 external rotor axial fan (compatible with data center dry coolers)

It meets the national first-level energy efficiency requirements, with a motor efficiency exceeding 90%. The air volume can reach up to 43500m³/h, the maximum power is 8kW, and the operating ambient temperature range is from -40℃ ~ +60℃.

It can achieve stepless speed change through 0–10 V analog quantity and PWM pulse signal, comes standard with RS⁴85 communication, and is equipped with built-in protection functions such as fault alarm output and motor overload protection.

 

EC355  external  rotor  backward-curved  centrifugal fan (compatible with  energy  storage inverter)

The integrated EC permanent magnet synchronous motor achieves energy  savings of over  35% compared  to  traditional   AC   fans. It    features    0-10V/PWM  stepless  intelligent  speed regulation, high temperature resistance, dust and vibration resistance, and is suitable for forced cooling in the nacelle of energy storage units and standby units. The narrow body design allows it to fit into compact equipment cabinets.

 

EC400 external rotor mixed-flow fan (compatible with energy storage air conditioning)

 

 

It combines axial flow's high air volume and centrifugal flow's high static pressure, featuring a diagonal flow duct for low dynamic pressure loss, compact design, and space-saving; it supports wide-frequency speed control and centralized network temperature management. It suits ventilation in energy storage battery compartment interlayers and silent generator set airflow.

The exhibition drew many customers for in-depth consultations and selections. We offered one-on-one solution matchmaking for needs like heavy-duty high-temp corrosion resistance, energy storage noise reduction, and data center efficient cooling. Over 200 customers visited on the first day.

 

 

 

Mingzhen Electronics maintains a dual-tech strategy: reliable AC series plus energy-efficient, smart EC series.
