Compact, user-friendly low dew point compressed air dryers
THE Sahara Series of compressed air dryers from Artic Driers International is designed to deliver reliable low dew point performance in a compact, robust package. The SA Series heatless twin-tower adsorption dryers combine durability, efficiency and intelligent control.
Designed with a small footprint and heavy-duty construction, the SA Series features patented free-floating shuttle valves that control both inlet and outlet air on all units. Changeover between desorption and online drying is handled by two rugged angle-seat valves, actuated by pneumatic valves and managed through the user-friendly HCD1 timer control system. This configuration ensures consistent operation and long service life with minimal maintenance.
Larger Sahara units are mounted on a “Low Ride” heavy-duty frame equipped with forklift slots and lifting shackles, simplifying logistics and installation. All dryers are engineered to comply with local SANS 347 directives, with alternative pressure codes available on request.
Advanced control features
All Sahara dryers are fitted with the HCD1 control box, which allows trained personnel to adjust drying and re-pressurisation times when required. A countdown display on the fascia provides clear visibility of the dryer’s status within each cycle. The controller can also be integrated with a compressor stop/start sequence, ensuring coordinated system operation.
A 4–20 mA output enables plant control systems to monitor dew point status and initiate corrective action if required.
The controller also includes an optional dew point control function, using a SUTO iTEC™ dew point probe to trigger tower changeover only when the target dew point is reached, significantly reducing purge air losses.
