GRT Series

Pioneer company in the manufacture of industrial steam turbines in Brazil, NG Metalurgica now makes available to the Brazilian market, the avant-garde technology represented by the GRT Series of turbines, thanks to a Technology Transfer Agreement signed with Alstom, a company with over 100 years of experience with this type of equipment.

Highly Efficient and Compact

With this tested and highly reliable technology, the GRT series of turbines provide customized solutions for efficient and flexible power and heat production.

They incorporate a modular concept with a plug-and-play type of assembly, which reduces times and costs of transport, installation and commissioning.

The modern GRT turbine project was inspired on the present day needs of power generating plant operators, which require flexibility and reliability while they provide power in the most efficient manner possible.

The GRT series offers individualized construction options for steam extraction, as result of their modular architecture, which completely meets the requirements of applications in the industrial and power generation markets.
