The screw compressors is increasingly demanded on the market. Many companies have been producing this type of compressor. The development of new types of dimensions must and is accompanied by the need to develop and modernize the test stands. The design and construction of a multifunctional stand took into account the various assortment of screw compressors – suction / discharge pressure variation, flow, speed. The test allows for different test configurations. In the stand the compressors are subjected to the mechanical test, followed by the performance test for the new compressors.The paper presents the solutions chosen for the multifunctional stand.
