Sahara­Pak Heat­of­Compression Air Dryer

Model HC Theory of Operation Left Tower Heating Hot air directly from the compressors enters the inlet of the HCand is directed by the inlet 2­way valves into the regeneratingtower. This hot, thirsty air regenerates the bulk of the waterfrom the desiccant. The air is then directed into the aftercoolerwhere it is cooled, the coalescing separator where liquid wateris removed through the drain trap system, then into the dryingtower where the air is actually dried to its final low dew point.

Left Tower Stripping The heating cycle lasts 90 minutes. At the end of heating, the inlet valves shift position, directing the hot inlet air directly into theaftercooler, separator, and drying tower. We now begin stripping. The stripping phase of regeneration lasts 90 minutes. At thebeginning of stripping, the regenerating tower is depressurized through a muffler. During stripping, a small adjustable flow of dry air isused to re­move the last little bit of moisture from the regenerating tower. The allows the HC dryer to provide exceptionally low dewpoints.

Left Tower Cooling At the end of stripping, the regenerating tower is repressurized. The outlet cooling cycle valves open and cooling begins. Duringcooling, a portion of the dry outlet air is directed into the regenerating tower to reduce the temperature of the bed prior to towershift. There is no air lost during cooling. Cooling and stripping combine to provide extremely low dew points and to eliminate dewpoint fluctuations during tower shift.
