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
