From Kaeser Compressors, Inc.

Desiccant dryers are commonly used to bring the pressure dewpoint well below freezing (commonly -40°F) in order to prevent moisture from precipitating in the compressed air system and production equipment. In most cases, the need is actually seasonal and a refrigerated dryer is perfectly capable of meeting air quality needs for most of the year - and with much lower operating and maintenance costs. It is possible to install separate refrigerated and desiccant dryers in series for these applications. Better still are combination or "hybrid" dryer systems that combine dryer technologies into a high performing dryer with even lower operating costs.

Products & Services
Compressed Air Dryers
Compressed air dryers utilize technologies such as refrigeration, desiccant adsorption, and membrane filtration to remove contaminants, particularly water, from the air.
Air Compressors
Air compressors are machines that compress air to higher than atmospheric pressures for delivery to pneumatic or robotic tools, industrial equipment, or direct-use applications.
Compressed Air Filters
Compressed air filters are used to remove water, oil, oil vapor, dirt, and other contaminants from a compressed air supply.
