Donaldson Ultradryer HRE+ heat regenerated adsorption dryers can be used in all climate zones and provide easy maintenance and low investment costs.
As with all externally heated adsorption dryers, the desorption of the moisture adsorbed in the desiccant of the Ultradryer 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, Ultradryer HRE+ models can be used in all climate zones
