Electric Inverter Variable Speed Screw Air Compressor Advantages

DENAIR VSD (Variable Speed Drive) rotary screw air compressors are ideal for customers who require different amounts of air supply and extremely accurate pressure control. They help optimize production processes and improve productivity.

The principle of VSD is to automatically adjust the motor speed based on actual air demand. This reduces system pressure and total energy consumption, potentially cutting energy costs by 35% or more.

VSD air compressors reduce energy consumption through:

1. Eliminating inefficient processes from full load to unload
2. Avoiding power during unloading
3. Keeping pipeline pressure drop under 0.1bar
4. Reducing average working pressure
5. Lowering system pressure to reduce leakage
6. Soft starting method increases current balance and avoids current surge
7. Flexible choice from 4 to 13bar which reduces power consumption most.
