In mitny chemical plants w h e r e low-pressure steam is used for processing, General Electric mechanical-drive turbines are doing double duty—and producing w o r t h w h i l e p o w e r savings. First, t h e y act as reducing valves to b r i n g h i g h pressure process steam d o w n t o utilization levels and, second, they provide low-cost power t o drive a w i d e vari ety of? processing machinery such as pumps, blowers, com pressors, milling machinery, and kilns. Some of the appli cation possibilities for small turbines in chemical plants are illustrratecl a t the left. You can probably t h i n k of other uses i n your own plant. Wherever you apply t h e m , y o u ' l l find c h a t General Electric mechanical-drive turbines are simpl-e, efficient drives, easy t o install and easy t o maintain. They are not usually aiFected by h o t or d a m p atmospheres and \rery often can be safely used in hazardous areas.
