HRS-L series. Heat Regenerated Adsorption Dryers
The Ultradryer HRS-L+ range is designed for drying of compressed air and nitrogen in a pressure range up to 10 bar. The drying process is based on adsorption of water molecules out of a gas stream on hygroscopic desiccant materials. With this drying concept pressure dewpoints of -70°C (at 7 bar) or lower can be achieved.
The regeneration of saturated desiccant is done by using ambient air for the desorption of water and cooling the hot desiccant with ambient air in a closed-loop system.
The pressure vessels and all main process pipelines are made of steel material with flange connections.
An electrical control system with SIEMENS S7-1215C PLC and touch display SIEMENS KTP700 enables automated control of all phases of the drying and regeneration cycle. It includes the dewpoint monitoring and control system Ultraconomy for energy efficient and reliable operation.
