GPS SERIES
HEATLESS REGENERATIVE DRYERS |
Heatless Regenerative Air dryers are labeled "Heatless" because no external heat source required for regeneration.
The system utilizes retained heat of adsorption generated from the previous adsorption cycle. Great Lakes Series GPS Air Dryers
automatically deliver a standard –40F pressure dew point. The model series can optionally attain dew points as low as –100F. The system is easily maintainable and is extremely reliable in both dew point suppression and mechanical reliability. |

The GPS Series is most economical in systems with moderate air volume, because of low operating costs and original equipment purchase. Systems with high air volumes tend to have
prohibitive operating costs, due to the 14% purge rate. |
SEQUENCE OF OPERATION Compressed air laded with moisture vapor enters the
system through the right inlet valve and proceeds to enter the desiccant bed through the stainless steel diffuser screen. The air flows up from the bottom of the tank to the top allowing separated and condensed liquid to
remain at the bottom of the vessel not contaminating the rest of the desiccant. The dehydrated compressed air the exits the right vessel through the top stainless steel diffuser screen, and past the outlet checkvalve. A
percentage of the dry air is directed and metered to the left desiccant bed for regeneration. The adsorbent purge air enters the desiccant bed from the top and flows down collecting moisture from the desiccant. The now
moisture laden purge air exits the system through the purge valve and muffler. Several seconds before the cycle nears completion the purge valves closes and allows the regeneration vessel to equalize pressure with the online
tower. The cycle completes and the inlet valves invert continuing the cycle. |
