PSA stands for Pressure Swing Adsorption: pressurised air is fed into an adsorber, where its moisture is adsorbed on a
desiccant. Regeneration is achieved by relieving the pressure and purging the regeneration air through an adsorber.

The benefits of our PSA adsorption dryer:

• Small-sized and highly economical packages
• Short cycle times (6-10 minutes)
• A small amount of drying agent required per cycle
• A simple process

In the world of hydrogen production, the removal of O2, H20, KOH and other contaminants in the produced hydrogen after electrolysis has gained critical importance. The presence of these contents can compromise the quality of hydrogen. Hadetec technologies offers an effective solution for this specific challenge.

The adsorbent selection depends on ambient conditions, dewpoint and adsorption pressure. We tailor our dryer to meet these specifications, quickly achieving the required dew point. With PSA, we can accomplish dew points of -5 up to -70 degrees Celcius.
