Compressed Air Dryers

Water in your pipework?

Compressed air dryers, refrigerant & desiccant

Compressed air dryers are designed to remove water from your compressed air system preventing water being carried into your process equipment, often with disastrous results. Whilst the concept is simple, making sure moisture is correctly removed under all climatic conditions, at all times of year, regardless of the amount of air being used can be challenging. A good understanding of your working environment and the compressed air system is essential to get the correct dryer specified and installed.

REFRIGERANT DRYERS

Refrigerant dryers are the most appropriate dryer for most applications. Based on a simple refrigeration pump, they are cheap to operate and maintain. They create dry air with a dew point down to approximately 3°C. This is perfectly acceptable for most industrial applications.

Before leaving the dryer the air gets re-heated back to room temperature to prevent condensation forming on the buildings pipework.

DESICCANT DRYERS

Desiccant dryers use a granular absorbent chemical to take moisture out of the air. This chemical process produces air that is much dryer than air that from a refrigerant dryer. Typically desiccant dryers produce air with a dew point of -20°C to -40°C. Desiccant dryers are more costly to buy and operate and require larger compressors to be specified since there is a certain amount of air loss in the regeneration process of the absorbent chemicals. Zero loss dryers are available.

Desiccant dryers are usually required in applications where very high quality air is required, such as in food, electronics and pharmaceutical industries and sometimes in high quality paint spray applications.
