Viking Forge was experiencing sustained temperatures as high as 130°F. The facility’s exhaust fans were overloaded by the hot, dirty air and suffered frequent breakdowns. Even when the fans were in operation, the work floor still filled with hot, stagnant air. It was a brutal environment for the employees running the presses.

Moffitt performed a Computational Fluid Dynamics (CFD) analysis to find the right ventilation solution for Viking Forge. As it stood, the current ventilation system was designed to move 143,000 CFM of air. The model showed that this was inadequate and that the hot air was building up and exhausting through the open truck doors. Computer analysis determined that it would actually take 539,000 CFM to keep the building at a comfortable temperature.

Moffitt suggested a new system of eight Labyrinth natural ventilators to better exhaust the hot air. Moffitt also added seven wall louvers to provide much-needed intake air. It is projected that this new system should drop the temperature by an average of 40°.

In the end, switching to natural ventilation also meant the elimination of operating and maintenance costs incurred by running exhaust fans.

Moffitt Mechanical performed turn-key installation service on this facility. The wall louvers are adjustable and the ventilators all have motorized dampers installed to keep the heat in the building during the cold Ohio winter.
