There are several dryer types and systems. An FD or FX refrigerant dryer giving a dew point of 3 Celsius will be sufficient. However, offshore, dredging and working vessels require a dew point of minus 70 Celsius. This can be achieved with a CD dryer, also called an absorption dryer.
For applications remotely fitted from the compressed air outlet of the compressor on board, we can fit a membrane dryer, the so called SD dryer. Examples of this usage are: pneumatic level and sounding systems, dry air for purifier systems and compressed air application on wheelhouse or control rooms. A dew point of either 3 Celsius or 20 Celsius can be selected for the SD dryer.
For good dryer operation, various limitations need to be taken into account when designing the compressed air system on board the ship. The inlet temperature of the dryer is often limited, as is the working pressure. Atlas Copco offers dryers that can still guarantee a given dew point with an inlet compressed air temperature of 50 Celsius and a pressure of 20 bars.
Atlas Copco also offers dryers with heat regulation, VSD drive and energy efficient operating principles.
