In nearly all areas of the industry compressed air is one of the indispensable working medias. The application as working, conveying, measuring, control
and regulating air is just as self-evident as the application in the process technology. The atmospheric inlet air of the compressor contains harmful substances and impurities. Moisture in the form of vapour is condensed out into the compressed air network. This causes expensive damages and a
loss in quality.
Regeneration of the dampened bed is carried out in two steps, depending on the type:
The desorption and cooling in the HRS system variation is also accomplished with the ambient air drawn in by the blower. Compressed air will not be used during the desorption or the cooling phase.
Since the desorption occurs in counter current flow,
a low energy consumption is required. The HRS is
therefore the most energy efficient option
As with all externally heated adsorption dryers the desorption of the moisture adsorbed in the desiccant of the HRE models takes place with the heated blower air stream. The cooling of the desiccant is conducted with partial flow of the already dried compressed air. Because the cooling process is independent of the ambient conditions the HRE models can be used worldwide
It is possible to develop an individual project for a given application.

Adsorption dryer where regeneration takes place using an external heat source. Dehydration occurs in the opposite direction to adsorption when using externally heated gas in a closed circuit (no consumption of compressed gas). In contrast, the cooling occurs in the opposite direction to adsorption using dried compressed gas in a closed circuit.
Automatically regenerated natural gas dryers for gas distribution stations for wheeled vehicles do not generate losses during drying.
Currently implemented types:
(After painting mounting all unpainted parts, such as air control tubes, manometers, transmitters, wiring, …)
0-10 bar compressed air (compressor), 10-20 bar nitrogen (gas cylinders)
(Working pressure: 18.6 bar; design pressure of the tank 22 bar)
(After final assembly – control of the heater, blowers, actuators, valve terminal, …)
