Natural Gas Power | Ulysses, KS

Rubart Station


Mid-Kansas Electric Company came to Moffitt for a complete turn-key ventilation solution for their new 110 MW natural gas power plant. Moffitt in turn designed, manufactured, and installed the entire system. Moffitt installed a large MoffittVent™ along the ridge of the main turbine building. In addition, this allows for the heat from the 12 state-of-the-art natural gas-fueled reciprocating engines to easily exhaust from the building. Supported by wall fans for supply air the natural ventilator helps keep the building interior cool. During the colder months motorized dampers close off the opening and heaters keep the facility warm. Roof fans were also installed for spot cooling in select locations. These individual elements all work together to ensure the building maintains optimal ventilation throughout the year.
