Desiccant Air Dryers

Industrial Uses

Suitable for a variety of industrial sectors, including food, beverage and pharmaceutical, a typical Oxair desiccant air dryer pays for itself in less than a year. How? By reducing and eliminating maintenance costs and downtime, making your operation more productive.

How it Works

Dry air keeps pneumatic equipment running at peak efficiency and extends the service life of air tools, motors and cylinders. It does this by passing compressed air through a pressure vessel with two ‘towers’ filled with an alumina desiccant bed. This is the material that adsorbs water from the compressed air and the bed becomes saturated, regenerated in the next cycle.

The dryer is timed to switch towers based on a standard timing cycle. During the drying cycle some compressed air from the system is used to ‘purge/Dry the depressurized desiccant offline bed.

As long as the compressed air is not exposed to temperatures below the air temperature dried in the desiccant air dryer (the dew point temperature), no troublesome liquid will form in downstream air lines and equipment.

Electric and Pneumatic Formats

Oxair’s desiccant air dryers are available in both electric and pneumatic control formats. We also offer conversions on customers’ own air-drying equipment. Our systems are PLC controlled with reliable HMI touch screen.

Air flows can be achieved from 100 SCFM to 10,000 SCFM, with pressures from 100 psi to 500 psi. Certified lifting frames are available as well as the multi stage filtration system for maximum protection. We offer AS-1210 or ASME V111 stamped pressure valves and the system has a super quiet muffler for noise control.

Desiccant Air Dryers – Ease of Use

Designed for consistent pressure dew points, -40°C to -60°C, Oxair’s desiccant air dryers eliminate water and freezing ice in low ambient temperatures. The system comes completely assembled, piped and wired with a full charge of activated alumina desiccant. The only thing that needs doing for operation is to hook the system up to the utilities.
