Screw compressor with direct drive and frequency control (stationary)
1.04 - 34.7 m³/min, 8 -13 bar | SLF, SLDF series
BOGE
Adjusting the motor speed to fulfil the varying free air delivery requirements is the most efficient operating method when the system has considerable fluctuations, limited air receiver capacity or when the compressor is operating as peak load compressor.
Advantages of frequency control:
- Smooth starting and stopping within seconds
- Continuous volume flow control from 25 to 100%
- Flexible adaptation of free air delivery
- Reduced costs for wearing parts and maintenance
- No start-up current peaks (energy saving!)
- Constant net pressure +/- 0.1 bar (energy saving!)
- Almost no idle operation (energy saving!)
SLF/SLDF series
- Matches demand perfectly
- Controls pressure precisely
- Optional radial fan or super-silencing for significant sound pressure reduction
- Option with integral refrigerant dryer: the ultimate energy saving, space saving solution
The BOGE SLF/SLDF series combines a direct coupled drive system with frequency control to provide the ultimate compressor for pressure control under variable output requirements.
In this direct coupled series the frequency convertor assures the smoothest possible transition from 25-100% to maintain pressure and output perfectly.
