Desiccant Compressed Air Dryers
Clean and Dry Compressed Air
Compressed air is an important source of energy for industrial applications. The need for an air supply to be clean and contaminant free is crucial. So too is the need for dry air without traces of water or oil vapor. Any form of moisture in a compressed air line has the potential to cause costly downtime, machine damage and product spoilage.
A heatless compressed air system is one of the most important determinants of overall system efficiency and represents one of the largest opportunities for energy savings on any site. There can also be significant cost benefits of an efficiently designed and maintained desiccant compressed air system.
General Air Products’ line of heatless desiccant compressed air dryers offers a multitude of additional energy saving features, which allows the dryer to be linked with a compressor control system and reduces air consumption during periods of low demand.
The HDD Series from General Air Products
With flow rates from 4 scfm to 365 scfm the entire range can operate at -40°F pressure dewpoint as standard, with an option of -100°F for more critical applications. The range has been designed and engineered to meet the air purity class in accordance with ISO 8753:1-2001 (E).
The units have an intelligent diagnostic system installed as standard on each model. Ease of service has been foremost in the design. Each unit can be serviced without disturbing the surrounding pipework. Desiccant cartridges can also be changed out effectively without causing excessive down time.
