Abstract
A low-temperature dryer, especially a compressed air low-temperature dryer, for drying of a gaseous working fluid with cooling of the gaseous working fluid by use of a refrigerant comprises a pre-heat exchanger section () and a main heat exchanger section (), in which the pre-heat exchanger section () and/or the main heat exchanger section () comprises at least one, preferably elongated heat exchanger element. Cooling of the working fluid introduced to the low-temperature dryer occurs here in the pre-heat exchanger section () from the dried and cooled working fluid. Additional cooling of the precooled working fluid passed through the low-temperature dryer occurs in the main heat exchanger section () from the refrigerant, so that moisture is condensed from the working fluid. All flow channels () of the pre-heat exchanger section () and/or the main heat exchanger section () are formed essentially by hollow chamber profiles.
