The GTD-4/6.3/10RМ gas turbines are the bases of the GPA-4/6.3/10RM gas-pumping units, designed for application within gas-transportation and gas-storing compressor stations, rated at total output power from 4 MW and above.


The GPА-4/6.3/10RМ are the automated block-module complexes of technological equipment, designed for modernization and new-built gas-transportation and gas-storing compressor stations (natural gas extraction, transportation, storing and distribution).

The GPАs are made up of the full-readiness, transportable and quick-assembling blocks for quick installation, have the developed diagnostic and control system (incl. remote one) with high level protection, equipped with working and emergency lighting systems, heating, ventilation, grounding, automated fire-fighting and gas contamination control, noise-protection systems, etc.

The GPА-4/6.3/10RМ have all advantages of the GTD-4/6.3/10RМ gas turbines, as well as:

• block-module configuration - savings of floor space, mounting and maintenance costs, configuration in accordance with the Customer’s requirements*

• advanced diagnostic and control system with high degree protection - high usability and safety in operation

• high level of automation, remote control of operation - continuous presence of operational personnel not required, unmanned operation

• meeting the current and advanced requirements of oil-and-gas companies

* - in accordance with the Customer’s demand, the GPА-4/6.3/10RМ can be equipped with pumps of various types, optional equipment / systems.
