SECCANT Regeneration Dryer - Safe and Low Maintenance Drying of Air and Gases
High Pressure Dryer SECCANT

SECCANTReasons for drying compressed air and gases
Compressed air and gases contain moisture and other contaminants that, if not removed from the air stream, may cause serious damage to the compressor system, tools and test pieces. Costly repairs and maintenance can result from accumulated corrosion, icing and dirt. The development of a failsafe, cost effective regeneration dryer for operating pressures of up to 350 bar / 5000 psig is an answer to the rising demand for dry and clean high pressure compressed air and gases.

How high pressure dryers work
Drying of the air and gas stream is achieved through adsorption. The molecular sieve with very large surface area accumulates water molecules from the gas stream. This process is reversible, that is, molecular sieve saturated with water molecules can be regenerated by a desorption process. Regeneration is achieved using a partial stream (maximum 5%) of the already dried medium. The low requirement of air for regeneration is due to the large difference in pressure between the between the operating pressure of 90-350 bar / 1300-5000 psig and the regeneration pressure, which corresponds to atmospheric pressure of 1 bar / 14.5 psi absolute. The regenerating air is channelled through the saturated molecular sieve and regenerates the adsorber by means of the partial decrease in line pressure.
