Heatless
107 to 3,000 SCFMMPD Series are traditional heatless dryers design ideal for providing clean, dry air to -40°F for process applications and where air lines are subject to icing from freezing temperatures.
MPD Series with (EMS) are designed to prepare the offline desiccant tower for service, and then saving energy by managing the purge air function to minimze wasted energy.
Mattei MPD Series Series heatless desiccant dryers use about 15% of the process purge air stream capacity to strip the moisture off of the offline desiccant bed then, exhausting the water vapor to ambient.
Mattei’s patented Multi-Port Regeneration System affects superior desiccant bed regeneration and, as a result, provides better and more consistent performance. The Multi-Port Regeneration System injects heated purge air at precise points up and down the towers’ length providing a more balanced distribution of heat.

Digital Readout
The Control Center features a backlit four line character display that monitors operation and status. Regenerating countdowns and time remaining are included.
Sequence Annunciator
Indicates the status of each tower. LED’s indicate which tower is “on-line” drying, “off-line” regenerating as well as the regeneration stages.
Manual Stepping
Allows the operator to quickly and safely step the dryer through a complete 8 hour cycle, in a matter of minutes.
ThermaLocTM
The Control Center also controls Mattei’s “ThermaLocTM” heater protection system. ThermaLocTM ensures maximum reliability and eliminates the safety concerns often associated with heat reactivated dryers. Heaters are protected by a totally redundant dual shutdown system that utilizes independent contactors. In addition to the redundant temperature controllers, the system monitors pressure and shuts the heater down in the event of low line pressure. Blower purge dryers have controls to prevent the heater from energizing if the blower is not running.
Dual Mode Heatless Back Up System
Allows the dryer to function in either the primary heated mode or the auxiliary heatless mode. Should the system experience a temporary overload or a heater failure, the dryer can easily be switched over to operate in the heatless mode. This way the dryer will remain on line until such time as service can be conveniently scheduled. The Dual Mode Back Up System offers unparalleled flexibility, eliminates downtime and prevents business interruptions.
