with the variable-speed compressor from Ceccato Aria Compressa S.p.A.

Principle

Variations in the amount of compressed air required causes corresponding variations in line pressure.
Pressure variation is detected by the compressor delivery pressure sensor, which processes the signal
and transmits it to the control system.
The machine varies motor speed and keeps line pressure constant, adjusting automatically according
to consumption.
This means it only supplies the amount of compressed air required by the system.
The motor speed is regulated by varying the electric motor feed frequency.
Every re-start of the electric motor using the INVERTER is ramped, with limited current.
This means an unlimited number of startups can be performed, unlike traditional compressors with direct
or ASD startup.

Result

The IVR screw compressor, coupled to a system that electronically adjusts the motor's rotation
speed, ONLY CONSUMES the energy needed to produce the compressed air required by the system.
This saves over 20% in approximately 20,000 hours of operation compared to traditional equal power.
