Kaeser Air Compressor

Clean waste water – without the fuss

All compressor condensate usually contains trace amounts of oil. Accordingly, it's common in most cases for official regulations to apply which require compliance with a maximum oil content before condensate can be fed into the regular sewer system.

AQUAMAT oil-water separators remove dispersed oil – with type approval from Deutsche Institut für Bautechnik (DIBt). They enable legally compliant treatment of condensate – directly where it arises and with no energy consumption.

To meet specialised installation requirements, we offer electronic level sensors, tested oil pans and frost protection heaters. Special condensate distributors are available for a parallel hook up multiple separators with equivalent condensate load. 

Your advantages

Cut disposal costs by 90 %:

Having your condensate picked up and treated externally by specialists is expensive. With AQUAMAT, only residual quantities of toxins remain for disposal – cutting typical disposal costs by some 90 %.

Extended filter service life:

All CF models use powerful synthetic fibre filters with enhanced filtration capacity (not activated carbon). Models CF9 and higher feature a settling chamber upstream of the filters in which floating oil is drawn off into an external collection container by an overflow. This reduces load on the filter and also extends the service interval.

Straightforward handling:

You can visually check the quality of the purified waste water using a reference turbidity set. The models with a main filter cartridge are especially user-friendly as they can be pulled out using handles and fixed in place to drip dry – clean and straightforward.

An overview of system cost-effectiveness

Thanks to savings of around 90 % on typical condensate disposal costs, AQUAMAT investment costs are quickly amortised whilst the AQUAMAT itself contributes significantly to the cost balance of your entire system over the long-term – an aspect that's central to KAESER's approach.

Compact and refined, but with significantly more power than comparable products, Kaeser Kompressoren is proud to introduce its latest generation of high efficiency ASK series rotary screw compressors. These innovative compressors not only deliver more compressed air for less energy, but also impress with their user- and service-friendly design.

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.

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.

Future-ready with IE4 motors: ESD series rotary screw compressors from Kaeser are now equipped as standard with energy-saving motors and high-efficiency Sigma airends. The prime benefits: even lower energy consumption for significant energy cost savings.

Energy-saving, environmentally-friendly fluid filter

The principles of resource conservation are also consistently applied inside the compressor unit: the environmentally-friendly fluid filter elements now simply sit in an aluminium housing, with no need for a sheet metal enclosure. The filter elements themselves are completely free of metal, making disposal straightforward: at the end of their service life, they can be thermally disposed of without additional pre-treatment.

Controller ensures optimised operation

The advanced “Sigma Control 2” compressor controller provides comprehensive monitoring of the compressor and, if equipped, the frequency converter (SFC variable speed control option). It also enables the compressor to utilise powerful networking solutions and allows straightforward connection to a master control system, such as the Sigma Air Manager 4.0, or to a control centre.

Durable and straightforward operation

Oil-lubricated reciprocating compressors deliver high pressures and flow rates for industrial applications. Harmful gases in the ambient air are removed by the lubricant. Kaeser offers two versions of oil-lubricated reciprocating compressors:

• For fail-safe dependability: Dual units comprising two compressors and an air receiver
• For integration into individual or existing systems: Integrated base-mounted units

The compressor blocks feature the following performance parameters:

• Pressure: 10/35 bar
• Flow rate: 60 – 1400 l/min

Your advantages

Longer service life thanks to low speed:

thanks to operation at just 1500 strokes per minute, our compressors ensure low energy consumption and long service life.

Moreover, the units deliver full performance right from the first hour of operation –

and maintain this standard throughout their long service life.
