When you work with compressed air, you inevitably have to deal with a natural by-product: condensate. Although it may seem like just "some water", condensate is made up of water, oil and dirt particles. Poor drainage of this mixture can lead to damage to your pneumatic components, loss of production and high costs.

 

In this article, we'll explain exactly what condensate technology is.

 

What is condensate and how does it form?

Compressed air always contains a certain amount of water vapour. Once the compressed air is compressed and then cooled down in pipes, aftercoolers or air dryers, the air can no longer retain this vapour. The result? Droplet formation, or condensate.

 

However, in an average pneumatic system, this is not clean water.

 

It is an aggressive mix of:

• Water

• Oil residues (in oil-lubricated compressors)

• Dust particles and dirt from the intake air

• Rust particles from pipes

The higher the humidity and the greater the pressure difference, the more condensate is formed.

 

That is why condensate is mainly present:

• Immediately after the compressor

• In air receivers

• Before and after air dryers

• In distribution pipes

Why is good condensate technology indispensable?

If you don't process the condensate correctly, you'll face the following issues:

1. Corrosion: Water in your pipes causes rust, which destroys your valves and cylinders from the inside.

2. Product damage: In applications such as spray painting or food processing, moisture in the air can ruin the entire batch.

3. Freezing: In winter, external pipes can freeze and block.

4. Lubricant loss: Water washes the necessary grease out of your pneumatic tools, which ensures faster wear poor performance of critical components of pneumatic cylinders and valves 

 

Condensate technology that works: the three core principles

To keep your system dry and efficient, you need to look at three parts: separation, disposal, and treatment.

1. Water Separators and Filters

Water separators and compressed air filters ensure that moisture and contamination are removed from the airstream early on. This protects sensitive pneumatic components further down the system.

2. Condensate drains

If there is water at the bottom of your boiler or filter, it must be removed. You can choose from the following methods: Manual drain: Cheap, but error-prone (you shouldn't forget). Time-controlled tapping: Works with a timer. Effective, but often loses unnecessarily expensive compressed air. Level-controlled drain (Electronic): The most efficient choice. It only opens when there is real water present, so you waste zero compressed air.

3. Oil-water separators

Legally, you cannot simply discharge condensate containing oil into the sewer. An oil-water separator removes the oil from the water, so that you can dispose of the clean water safely and according to environmental regulations.

 

Tips for an optimal system

• Check your filters regularly: A saturated filter allows condensate to pass through to your machines.

• Choose quality: Cheap drains often leak compressed air, costing you hundreds of dollars in energy costs on an annual basis.

• Check your dew point: The lower your dew point, the drier the air. With an air dryer (cooling or adsorption dryers) you lower the dew point of the compressed air. 

Benefits of good condensate management

Condensate technology is an indispensable part of any pneumatic system. By investing in the correct drainage, separation and treatment of condensate, you protect your installation, prevent downtime, reduce costs and increase the reliability of your processes.

Frequently Asked Questions (FAQ)

What is condensate in a compressed air system?

Condensate is formed when moist compressed air cools down. It consists of water, oil and dirt particles that collect in pipes, boilers and dryers. Without proper drainage, this can cause damage to your pneumatic installation.

 

Why is good condensate drainage important?

Good condensate drainage prevents corrosion, blockages and wear in your compressed air system. By removing condensate in time, your compressed air stays dry and you extend the life of your installation.

 

Why does condensate need to be separated and treated?

Condensate often contains oil and contamination and should not be disposed of untreated. By separating and treating it, you prevent environmental damage and comply with laws and regulations.
