Product Details

250KW Permanent Magnet Variable Frequency Drive Compressor energy saving 35-50% in TUV certificates 5 years warranty

Why Permanent Magnet Variable Frequency Drive Compressor energy saving 35-50%?

1)High efficiency,cost-effective

2)Better stability with frequency starting

3)Constant pressure air supply

4)Energy-saving and long running

5)Pretty good after-sale service

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

Shanghai rotorcomp Variable speed drive Screw Air Compressor adapting the amount of free air delivered to compressed air demand is the most economical operating method where demand for compressed air fluctuates considerably or where the stored volume is very small or where operating below peak load.

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
