With turbine exhaust pressure a vacuum, the condensing multistage turbine is a high-efficiency, high output model capable of fully converting the thermal energy of steam to velocity, without loss.

This series of products are known as 'multistage' steam turbines and are characterized by two or more rotor discs mounted on the shaft. The number of stages and the average pitch circle diameter (PCD) of the rotor discs are optimized to suit output, revolutions, inlet steam pressure, temperature and exhaust pressure.

Subject to the number of stages chosen, the nozzles, blades, rotor discs, shaft and casing may be varied, but other essential components are fully standardized and have been engineered to fit easily to any model. SNM has a comprehensive inventory of standardized components, stock controlled to ensure prompt and reliable supply.

The SNM Type C condensing multistage steam turbine performs power recovery in biomass, cogeneration, solar power, and other renewable energy applications that help address global warming and related environmental problems. The Type C supports electricity generation by independent power producers (IPPs), combined cycle plants, sugar refineries, paper mills, plywood factories, and other industrial facilities. In addition, the Type C drives air compressors; induced- and forced-draft boiler fans; high-temperature, high-pressure boiler feed pumps; and high-capacity gas compressors in oil refineries and petrochemical, ammonia, and ethylene plants.

The Type C may be customized to conform to API 611 or 612.
