DRYER

摘要

A compressed-gas dryer (1) includes a cooling system (10) supplied by gas entering the dryer (1) and emitting dry gas at the output, including a cooling circuit (20) comprising a thermal exchange module (13), in which a refrigerant circulating in the said cooling circuit (20) exchanges heat with the said incoming gas. The cooling circuit (20) also includes at least a first compressor (21a) and a second compressor (21b) capable of compressing the refrigerant downstream of the heat exchange module (13), a first and a second inverter associated with the first compressor (21a) and second compressor (21b) of the cooling system (10) respectively, a control unit (27) and in which said first and second compressor (21a, 21b) deliver a smaller and larger flow rate respectively for the same pre-set operating pressure.
