There are several types of dryers, and each has specific advantages and technical characteristics. To choose the one that best suits your needs, you must consider:

• Its intended use
• The dew point*
• The temperature required for your compressed air
• The frequency of compressed air use in the process
• The location of your air compressor

*The dew point is the temperature at which the air becomes saturated and condensation occurs.

• Use an intake filter to purify the air before it enters the compressor. This will minimize the risk of contamination.
• Store compressed air in a separate tank to further reduce the risk of contamination.
• Schedule regular preventive maintenance to keep your compressor in optimal condition.

Refrigerated dryers are affordable and easy to set up, present low maintenance costs and are known for their resistance to oil particles.
However, they’re not suitable for freezing temperatures and have limited dew point capacity.

On the one hand, desiccant dryers can achieve very low dew points, have reasonable operating costs, and are suitable for remote or hazardous locations.
However, they have high installation costs and are particularly sensitive to oil contamination. Their desiccant material must also be replaced every 3 to 5 years.

Now let's talk about chemical dryers. These are chosen because they require minimal monitoring and have low initial setup costs. They also have no moving parts.
However, they do have some disadvantages, such as :

Regular chemical replacement is costly

• Require high-quality filtration
• Chemical disposal can be expensive and time-consuming

Membrane dryers don’t require any electricity, are quiet and easy to maintain.
On the other hand, they require consistently clean air and prefilter to keep the membrane protected.
