Depending on your application or industry, you will need dry, clean or even sterile compressed air.

What is the right air treatment for your requirements? If you are unsure we would welcome your enquiry to allow us to make a recommendation.

The atmospheric air drawn into a compressor is a mixture of gases that always contains water vapour. Unfortunately air under pressure has less capacity to hold moisture and this gives rise to condensate in your compressed air.  The most common and cost effective way to eliminate moisture problems is to use a refrigerant air dryer.  A refrigerant dryer cools the air and removes all the condensed water at that point, then reheats the cooled air against the incoming untreated air.  Moisture in your air can cause significant reliability problems and after installing an air dryer many customers comment to us they wished they had done it sooner!

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 and valves free from contaminants. It therefore not only reduces service, maintenance and repair costs, but can also reduce initial investment costs.

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 (eg: 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.

Local authorities are becoming increasingly active in enforcing the correct discharge of waste streams. No effluent is permitted to be discharged to storm water drains; however regarding waste to sewer they “consider the installation of any oil retention system to be beneficial, and essential with respect to maintaining effluent compliance and preserving the environment.”  KAESER's AQUAMAT condensate treatment systems will ensure that contaminant levels are kept well within regulation limits.
