Ultrapac Classic ALD/MSD heatless desiccant compressed air dryers benefit from decades of design and fabrication experience by Ultrafilter. Our dryers are designed to consistently provide quality air with high energy efficiency in a flow range from 3 to 5,000 scfm. Operation is fully automatic with a guaranteed outlet dew point of -40?ø F or -100?ø F.
During normal operation, Ultrapac dryers operate on a fixed cycle divided into drying, regeneration and repressurization stages. No adjustment to this cycle is made for changes in dryer inlet conditions such as flow rate, temperature or relative humidity, all of which affect the load on the dryer. When operating in Ultraconomy mode, the dew point of the process air is monitored at the dryer outlet to determine whether or not regeneration should be initiated.
