Industrial Screw Air Compressor VFD - SF
(45 KW - 110 KW)
the energy saving solution for fluctuating demands
SF Frequency Controlled Series.
Eliminate off load running, even out demand fluctuations and save energy. The SF series works strictly in accordance with the compressed air demand by producing the exact volume of compressed air at the pressure required.
Correctly specified frequency controlled compressors eliminate idling time and even out air demand fluctuations. Energy costs can therefore be reduced considerably. Continuous flow regulation from 25-100%
Constant system pressure
- universally adaptable to changing operating conditions
Smooth start-ups and run-downs in a matter of seconds
- no energy costs arising from generating unnecessary pressure (1 bar excess compression equals 6-10% increase in energy costs)
Easy to integrate into existing compressed air stations
- little wear on components and short reaction times
Complete product range based on standard modules
- easy optimization of compressed air supply
: Start-up power within the nominal power range
Practically no idling time
- practically no power peaks during start-up
- large potential saving on energy costs
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 when operating below peak load.Benefits of frequency control:
- Smooth starts and stops within seconds
- Continuous volume flow regulation from 25 to 100 percent
- Flexible adaptation of f.a.d.
- Wear and maintenance costs minimized
- No power-peaks during start-up (energy saving!)
- Constant network pressure +/- 0.1 bar (energy saving!)
- Nearly no idling (energy saving!)
The SF series models are available in the following pressure ranges: 8 bar, 10 bar and 13 bar. Due to their continual flow regulation ranging from 25% to 100% they cover free air delivery in the range of 45 kW and 110 kW.
The SF series models have a frequency converter and separate control integrated into the switch cabinet in a space saving manner. The efficient control of the compressor is a standard feature in the SF series. The current operating conditions of the machine are displayed clearly and precisely in the LCD display.
SF series screw compressors can be ideally integrated into any existing compressed air station.Effective FAD: 62 - 650 CFM
Pressure range: 8 - 13 Bar
