Air Treatment Plant

 

Depending on application or industry, you will need dry, clean or even sterile compressed air. With KAESER you get compressed air qualities in which impurities are, in part, below possible levels of detection.

What is the right air treatment for your requirements? Click on the units listed on the left for more detailed information or contact one of our specialists for advice.

Drying

The atmospheric air drawn into a compressor is a mixture of gases that always contains water vapour. However, the amount of water vapour that air can carry varies and is mostly dependent on temperature. As air temperature rises – which occurs during compression – the air's capability to hold moisture increases also. When the air is cooled its capacity to hold moisture reduces, which causes the water vapour to condense. This condensate is then removed in the centrifugal separator, or the air receiver, downstream from the compressor. Even then, the air can still be completely saturated with water vapour. This is why, as the air cools further, significant amounts of condensate can accumulate in the air distribution piping and at take-off points. System failure, production downtime and costly service and repair work are therefore unavoidable without additional air drying.

Filtration

On average, a compressor sucks in up to 190 million particles of dirt, hydrocarbons, viruses and bacteria with every cubic meter of atmospheric air. The compressor itself can only remove the larger dirt particles and the majority of the contaminants remain in the compressed air. This means that for most applications careful treatment of the air is necessary: Clean, quality compressed air maximises air-tool service life, ensures that pneumatic machinery and control systems operate at the peak of their performance and keeps pipes & valves free from contaminants. It therefore not only reduces service, maintenance and repair costs, but can also reduce initial investment costs.

Compressed Air Storage

Due to its storage and buffer capacity, the air receiver plays a key role within a compressed air installation: It provides capacity during periods of peak demand and is often used to separate condensate from the compressed air. Therefore, it is important for the receiver to be correctly sized for the specific system, to be resistant against corrosion and to have long inspection intervals. Air receivers from KAESER meet all of these requirements. 

Air-main Charging Systems

Compressed air treatment systems are designed for a certain rate of air flow which, when the system is operating at full load, pushes against the pressurised air in the air distribution network. However, should this resistance not be present, for example during periods of low load or downtime, it is possible that dryers and filters may be overwhelmed by the sudden surge in airflow that occurs when the system re-starts. Air-main charging systems prevent this from occurring. They not only ensure consistent compressed air quality, but also enhance system reliability and significantly extend the service life of air treatment equipment.

Condensate Technology

Condensate is an unavoidable result of air compression. It is a chemically aggressive fluid that mainly consists of water, but also contains oil and dirt particles (e.g. rust). If not reliably drained off at all collection points, it can cause operational disruption and severely damage the compressed air system through corrosion. Experience has shown that float controlled drains become unreliable over time and that time-controlled drains can be a source of considerable air loss. The electronic level-sensing controlled ECO DRAIN provides the perfect solution. ECO DRAIN condensate drain
Condensate is an unavoidable result of air compression. It is a chemically aggressive fluid that mainly consists of water, but also contains oil and dirt particles. This combination of substances can consequently cause serious environmental harm if released in its raw state. Water resource legislation stipulates that contaminated water must be treated to achieve prescribed safety levels regarding purity. KAESER KOMPRESSOREN's AQUAMAT condensate treatment systems do precisely that: They ensure that contaminant levels are kept well within regulation limits (e.g. max. 10 or 20 mg/litre for hydrocarbons).
