Where the responsibility for complete power equipments is divided

the results can hardly be as satisfactory as when the machinery is all designed, built and installed by one company.

How is it possible to realize the highest efficiency
except through harmonious working of every detail?

In the absence of this no plant can yield the maximum output to be obtained from it under proper conditions, at the minimum expense per kilowatt-hour for operation and maintenance.

Allis-Chalmers Steam Turbine and Generator.

Any efficiency short of the highest attainable means
proportionate loss.

We build complete power and electrical equipments of every description, whether the prime mover required is a Steam Turbine, Reciprocating Steam Engine, Hydraulic Turbine or Gas Engine; and for each of these we are taking orders in large volume.

Because most purchasers realize the advantage of
having the complete equipment covered by one contract.
