<P>PROBLEM TO BE SOLVED: To provide a test bench conditioning system and a device for operating a system of this type, with which optimum simulation for the temperature profile of an operating fluid of a machine is possible with the slightest deviations from a preset profile. Ž<P>SOLUTION: The test bench conditioning system for a working fluid of a machine located on the test bench includes: at least one pump 3 for circulating the working fluid; a heat exchanger 4 for cooling the working fluid coming from the discharge line 1 of the machine; a heating device 5 for the working fluid, fed into the supply line 2 to the machine; and a mixing valve 6. Furthermore, a bypass 8 that can be shut off between the discharge line 1 and the supply line 2 can be provided. Setting the temperature profile for the working fluid is possible via a control device. In order to render possible an optimum simulation of a real temperature profile of an operating fluid of a machine with the slightest deviations for the predetermined profile, a connecting line 10 with a control valve 11 leads to the discharge line 1 in front of the mixing valve 6, which opens into this discharge line 1 in front of the pump 3.
