Who is This Solution For?

Data Processing Centers (Data Center), requiring 100% reliability

Medical Facilities with critical ventilation requirements

High-tech Manufacturing, where energy efficiency matters

Multi-Fan Technology

Multi-fan on EC fans is a grid of several identical EC plug fans operating in parallel in a single fan chamber. The total airflow is the sum of individual fan flows at the same pressure, providing flexibility, reliability and system efficiency.

Key Technology Advantages

Hot Standby (N+1)

Achieved using N+1 principle: install 1 (or more) "extra" fan. When one fails, the others automatically increase speed and maintain required airflow/pressure without stopping the unit.

High Energy Efficiency

EC motors are 10-50% more economical than traditional AC. Fan arrays operate with better efficiency at partial loads (cube law: P ~ n³). In real projects, replacing one large fan with an EC "wall" yields 25-60% energy savings.

Standardization to 1 Size

The entire supply system is assembled from one standard fan module, and the required airflow is achieved by the number of modules (2×2, 3×2, 4×3, etc.). This drastically simplifies spare parts inventory, procurement and service.

Economic Effect

25–60%

Energy savings when replacing one large fan with an EC "wall".

10-50%

Savings from EC motors compared to traditional AC + VFD.

Simplified maintenance and spare parts thanks to component standardization.
