Viking Forge Labyrinth Rooftop

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

Moffitt ran 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. The model projected that this new system will lower the temperatures by an average of 30°. In addition, 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.

RESULTS

With the new ventilation system, Viking Forge can now control its temperature conditions better than ever before. The Labyrinth vents effectively exhaust hot air in the summer, achieving the modeled temperature drop of  30°. On some days, and some spots, the difference is even greater.

Also, with the motorized dampers on the vents and the new adjustable wall louvers the building is able to retain the much needed heat during the cold Ohio winter. All in all, Viking Forge can now control its temperature conditions better than ever before.
