Boge D Series adsorption dryers

The Boge D Series adsorption dryers utilise the traditional twin tower system; however, each tower contains a cartridge that contains pre- and after-filtration as well as the desiccant media - while one tower adsorbs humidity, the other one regenerates the desiccant.

Saturated compressed air leaving the compressor enters the inlet of one of the towers via a water separator, which collects water in a special condensate chamber, before passing through the pre-filter in the cartridge. This system prevents any bulk water migration into the desiccant media. This water is then separated during regeneration of the reservoir. Next the air passes through the desiccant to adsorb the remaining water vapour from the air.

After the drying process the air passes through a particulate filter which is designed to collect any residual dirt or dust particles so that the air produced conforms to quality Class 2 according to DIN ISO 8573.1.

A volume flow regulator controls the flow of compressed air and prevents any overloading of the dryer. Simultaneously to the drying process, a small portion of the dried compressed air is directed through the other chamber to adsorb the media. The desiccant is therefore regenerated without any additional energy consumption.

The D Series adsorption dryer emits very low sound pressure levels of less than 60 dB(A). Flow capacity is 2.07 m³/min and maximum operating pressure is 16 bar.
