Sperre Equipment
Screw compressors
Air- and water-cooled screw compressors, fixed speed or VFD, for large volumes of low-pressure working air at 8 to 13 bar.
Description
Sperre screw compressors are intended for installations that need a large volume of low-pressure compressed air. An efficient air end design gives high output, reduced leakage and lower power consumption.
Key features
- Air-cooled (A) and water-cooled (W) fixed-speed models from S05A to S360W
- Variable-speed (VFD) models from S11A-VFD to S90W-VFD
- Pressure ratings of 8, 10, 12.5 and 13 bar
- Charging capacity at 8 bar: 51-3000 m³/h (fixed speed)
- Installation without special tools; internal air circulation cools heat-affected components
- Removable, fully enclosed cabin protects compressor and crew and reduces noise
- Maintenance schedule with service kits according to running hours
Applications
- Working and service air on board ships
