Adsorption dryers

For high-quality instrument air

When instrumentation and valve systems are exposed to moisture, their performance will become unreliable, and controls may malfunction. This results in costly downtime and possibly lower-quality output. 

Hence, the importance of instrument air: an atmosphere that is free of contaminants and moisture will contribute to optimal equipment performance.

Tailored to meet your requirements

To create instrument air, we offer various types of adsorption dryers, including PSA, TSA, zero purge loss, and heat of compression (HOC). All are tailored to meet your demands and built in compliance with  international standards. Any additional certifications can be arranged for - simply indicate which one you require, and we will engineer accordingly.

Below, we have listed the most widely used dryers: the PSA and TSA adsorption dryers.

PSA adsorption dryer

PSA stands for Pressure Swing Adsorption: pressurised air is fed into an adsorber, where its moisture is adsorbed by 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

Low dew points

The selection of the adsorbent 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. 

TSA adsorption dryer

Another adsorption dryer we offer applies Temperature Swing Adsorption (TSA): it dries gas at low temperatures and regenerates the adsorber at high ones. The temperature at which a saturated adsorber is generated depends on the required dewpoint, the process parameters, the gas composition and the used adsorbent. We tailor our design to meet the specs you need.

This process is slightly more complex, as more components are required: a heater, a cooler and a coolant. However, low outlet dew points can be obtained over long periods of time. Furthermore, the adsorber can be heated from various sources. This makes the TSA adsorption dryer highly suitable for large-scale processes.
