Description
The BERG BSDF series compressors have infinite rotation adjustment from 50% to 100%, (in special versions of screw compressors - from 20% to 100%).
The operation control system with the frequency inverter tries to maintain the compressor motor rotations at the level that ensures constant pressure in the compressed air system i.e. at the set level. When the network pressure decreases, the inverter increases the motor rotational speed, which results in the compressor capacity increase, and when pressure increases, the motor rotational speed decreases.
Variable engine speed in BERG BSDF compressors means ENERGY SAVING close to 40% of electric energy saving when compared to the compressors with traditional control.
