GTU-25P gas turbine for power generation rated at 25 MW


GTU-25P is intended to drive  electrical generators.

It is used as part  of GTES-25Đ generator set.

The gas turbine has been designed on the basis of the PS-90A aircraft engine which is a unique Russian engine of the fourth generation having Certificate of the international standard.

The GTU-25P for gensets  is a modified model of GTU-25P mechanical drive.
