Sorption technology for perfect process air drying

Benefits of an adsorption dryer

In most cases, conventional methods such as condensation of water vapor on cooling registers or heat exchangers are no longer sufficient to generate dry process air. In order to reduce the residual moisture content of the air to a minimum, sorptive processes are therefore necessary - implemented in an adsorption dryer.

The use of rotary dehumidifiers as adsorption dryers has proven to be particularly effective here. The moist air flow is passed through a rotating sorption wheel coated with adsorbent and dried in this way. On the opposite side, the wheel is regenerated in order to effectively guarantee the continuous processing of the air or process gases to be dried.

Sorption technology basics used in ULT Dry-Tec systems

System schematic sorption drying

The water molecules in the sextracted air are simultaneously driven out of the adsorbent by means of desorption and continuously through heat and consequently conducted as an adsorbate in a separate air stream from the system into the outside atmosphere.

By expanding the system technology, for example with pre- and after-cooler modules, dew points (dp) down to -65° C and thus a relative process air humidity of 0.05% can be achieved. These low dew point requirements are usually required for sensitive products.

Solutions for process air drying

ULT Dry-Tec modules with pre-cooler and after-cooler

The ULT Dry-Tec adsorption dryer can flexibly be adjusted to a wide variety of environments and tasks. Upon request, we design a system that exactly meets your needs. Whether it is the adsorption dryer module alone, or with / without pre- or aftercooler or both, depends on the application.

In addition, we offer a number of extensions as part of this air drying concept, e.g. the utilization of filter technology. We would be happy to discuss these add-on functions with you in order to provide you with the most suitable solution for dehumidifying and cleaning process air.

We will be pleased to support you!
