Boge launches energy-efficient adsorption dryer

The D series of reliable and cost-effective adsorption dryers incorporates new technology to ensure only high quality compressed air is generated. The dryers use traditional twin towers, but each tower contains a cartridge to enable one to adsorb humidity, the other to regenerate 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. Subsequently, the air passes through the desiccant which adsorbs 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 overloading. While drying takes place, 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.
