Adjustable Speed Oil Flooded Rotary Screw Compressor / Small Air
Compressor
The variable frequency compressor is a competitive product among
the high-grade machines, the quality of air end of servo variable
frequency compressor is excellent. The advanced molded lines ensure
the minimum specific power.
It is designed in the FEM strength analysis, to ensure the
stability and reliability of each part, and to realize long term
operation with no faults, low noise and long life.
Advantages:
1. World-leading "Made in Germany" Rotorcomp screw air end
2,25-30% energy saving than normal VSD compressor
3. wider 15-60hz adjustable-speed drive system
4. Intelligent touchable PLC control system
5. Double higher efficient VSD energy-saving motors in IE3
CE&MEPS
6. Unique driving guard system
7. ISO, TUV, GA, CE,SGS certificates
The benefits of rotorcomp VSD air screw compressor
>Smooth starts and stops within seconds
>Continuous volume flow regulation from 25-100%
>Adjustable-speed drive from 15-60hz
>minimization of wear and maintenance costs
>No power-peaks during start-up
> nearly no idling
Reduce Energy Consumption
The costs of power consumption account for 70% or more of all costs
during the operation. The electric charges of running air
compressor account for more than 40% of all the electric charges in
the factory.
The requirement of compressed air fluctuates violently in different
time every day, different weeks, or different months every year.
The range of fluctuation is 40% to 80%, Rotorcomp adjustable-speed
drive screw compressor can meet the user’s requirement exactly.
When the user needs less air delivery, Variable frequency inverter
can reduce the capacity and reduce the power consumption at the
same.
