Condensate Management

Condensate Management

When air is compressed inside an air compressor the air is mixed with oil to cool and seal the compression process. This oil is then removed from the compressed air, along with a small amount of water, in the separator system within the compressor. Unfortunately it is not possible to remove all the oil vapour from the compressed air (this is one of the reasons we fit air filters to the compressed air system), nor is it possible to remove all the oil from the water which condenses out of the compressed air. This results in an oily/watery solution coming out of the compressor and sometimes the receiver. This toxic liquid is called condensate and is present in all lubricated air compressors. Condensate management is the process of disposing this toxic mix in an environmentally friendly way. For information oil free compressors, since there isnt any oil in the compression process, produce only water condensate.

The water resources act and your compressor

The water resources act was introduced to place legal restrictions on industrial discharges to ground, waterway or storm drains. Raw condensate is treated as an industrial discharge. The need for  condensate management, to protect the environment is very apparent since just 250ml of oil can polute many acres of water surface. A relatively small 18KW compressor can produce many thousands of litres of condensate every year. This condensate can contain up to 1,000ppm of oil and other waste. Since 99.9% of condensate is water it makes sense to remove the oil and other chemical waste from the water so that the remaining clean water can be legally disposed of down a foul drain (maximum oil content that can be put down a foul drain is 20ppm). Our preferred condensate cleaning system is from Sepura, which provides a simple but effective cleaning solution using a patented sterling filter media reducing oil content of discharged water to less than 10ppm.

Key product features

  • An effective condensate management system helps you meet legal requirements and protect the environment
  • The system can be automated to run in the background so it never gets forgotten
  • The systems are simple to use and only require annual maintenance
  • Poor control of condensate can damage your compressor and downstream equipment
