In any competitive environment, success comes to those with strengths, the skill to apply them and who have a strong commitment to innovation – the same also applies to the energy efficiency of rotary screw compressors. To become a true efficiency leader therefore, it is crucial to meet both current and future requirements. The new DSD series from Kaeser meets all of these needs and more.

You can choose between the following models:

• for integration in your compressed air station: our basic model
• with refrigeration dryer for high compressed air quality: T versions (ASD, BSD, CSD, CSDX and DSD series)
• with variable-speed drive for optimal efficiency and broad control range: SFC models
• New: With synchronous reluctance motor: Significantly greater efficiency - especially in the partial load range - than comparable asynchronous systems enables considerable energy savings.
• as complete solutions with integrated refrigeration dryer and variable-speed drive: T SFC versions (ASD, BSD, CSD, CSDX and DSD series)
• Our fluid-injected rotary screw compressors are the perfect choice for industrial compressed air applications. We’d be glad to help you select the size and model that perfectly meets your requirements.

Your advantages

Exceptional efficiency:The use of IE3 motors has been mandatory in the EU since January 2015. Furthermore, we already use IE4 motors in our BSD – FSD models with 1:1 drive to provide you with even further energy savings. 

Longer service life:Electronic thermal management dynamically controls the fluid temperature of ASD, BSD, CSD, CSDX, DSD, DSDX, ESD and FSD series compressors. This not only saves additional energy, but also reliably prevents condensate formation and associated moisture damage.

The all-in-one compact compressed air package

Compressed air systems of the SXC series have been designed for trades and crafts. On only 0.62 m², they comprise all components necessary for air supply under a single strong polyethylene cover: a rotary screw compressor with SIGMA-Profile, a refrigeration dryer and an air receiver.

Your advantages

Connect and go:

Piping and installation of our integrated packages takes little time. Simply connect this compact compressed air package to the power supply and compressed air distribution network and you’re ready to go - that’s it!

Protection from corrosion damage:

Thanks to the integrated refrigeration dryer, the SXC package delivers high air quality and protects your tools and equipment from corrosion damage.

Simple maintenance:

All maintenance and service points are easily accessible once the SXC’s removable enclosure which is made of rotational moulded polyethylene is effortlessly lifted away. The electronic condensate drain can be inspected via a grille. Maintenance is simple and effective.
