The primary purpose of many steam turbine generator cogeneration projects is to conserve energy and get a quick pay-back on the investment, so keeping costs low is an important priority. At the same time, it is important to have a control system that is safe, reliable and easy to use. Ewing Controls custom designs each controls system individually so we can tailor the design of your controls to get the right balance between cost and sophistication.
