Exceptionally high energy efficiency

  • Energy savings of up to 12 % compared to other compressor models
  • Innovative bare-shaft compressors with new, highly efficient 4+6 rotor profiles in the low and high-pressure ranges
  • Large turndown due to the use of VFD technology
  • Optimised cooling by using cooling liquid (water or oil) in the double-walled bare-shaft stages
  • Motors of energy efficiency class IE4 or IE5; in connection with an integrated VFD
  • Direct drive by means of coupling and gear transmission for optimum drive efficiency
  • Stainless steel rotors in both stages to prevent corrosion
     

High reliability and durability

  • 100 % oil-free process air for sensitive applications, certified according to ISO 8573-1 Class 0
  • PFAS-free process air generation
  • Effective sealing concept for drive shaft and conveying chamber; minimisation of natural seal wear
  • Extended fields of application: options for using the package in hot, dusty (desert installation) or extremely cold (polar regions) climates.
  • Oil pressure lubrication for exceptional durability of the anti-friction bearings. Bearing life of up to 40,000 hours
  • Permanent oil level check by means of an electrical oil pressure switch
  • Reliable even in extreme climatic conditions thanks to the use of an oil cooler already included in the standard scope of supply
  • Optional acoustic hood for outdoor installation. Enables the machine with integrated VFD to be used outdoors even under direct weather conditions
  • Highly effective water separators ensure that condensate is drained as required
     


Reduced maintenance effort

  • Operation and maintenance exclusively from the operating and rear side of the package
  • Small footprint and side-by-side installation possible
  • On-site service on the compressor stages and the package
  • Effortless transport of the entire package using a pallet truck, fork lift truck or crane
  • No maintenance required for drivetrain components
  • Delivery of the package with a filled oil system enables quick commissioning

 

Smart oil system 

  • Mechanically driven oil pump on the drive shaft
  • Highly efficient oil pump with reduced energy consumption
  • Oil-lubricated anti-friction bearings with pressure lubrication achieve a service life of up to 40,000 hours


Permanently, intelligently reduced noise levels 

  • Minimum sound pressure levels thanks to intelligent noise reduction of the package
  • Innovative pulsation reduction thanks to the use of Venturi nozzles downstream of both compressor stages
