Abstract: The present invention relates to a compressor device (1) comprising:

a compressor installation (2) having at least one compressor element (3a, 3b, 3c) for compressing a suctioned gas,
the compressor element (3a, 3b, 3c) being driven by an electric motor (4);
a heat recuperation system (6) for recuperating heat from a compressed gas resulting from the compression of the suctioned gas,
the heat recuperation system (6) comprising a piping network (7) having an inlet (8) and an outlet (9) for a coolant, said piping network (7) being provided at this inlet (8) or outlet (9) with control means with a flow rate control state variable for modifying a first flow rate of the coolant in the piping network (7); and
a control unit (13) which adjusts the flow rate control state variable of the control means on the basis of a drive current of the electric motor (4) or on the basis of a second flow rate of the suctioned gas such that a temperature Tw,out at the outlet (9) of the piping network (7) is driven to a predefined level.
