Encore Wire


Encore Wire, a manufacturer of aluminum and copper wire products, had an unfortunate heat problem. The upper furnace level reaching temperatures of 140°. It was a challenge for the crew members to walk in that area let alone work. They called Moffitt to help find a better ventilation solution.

Moffitt looked at the air flow of the facility and determined that the heat from the manufacturing process was getting trapped in the tower’s ceiling. The good news was that the very hot production process and high ceiling, made this building an ideal candidate for natural ventilation.

Moffitt Mechanical supervised the installation of the Double Labyrinth natural ventilators on top of the galvanized tower. The ventilators were assembled on the ground and then hoisted into placed on the ridge.


When coupled with the intake air from the open dock doors, a very effective natural ventilation system established. Since installation building temperatures at the work floor have dropped to about 85°-90°. This translates to improved conditions at the upper furnace level as well. Overall, the building is much less smoky, the interior is brighter, and the entire facility is cooler and more comfortable.

Project Summary

  • Two (2) 10’ 6” × 20’ Labyrinth natural ventilators
  • Two (2) 10’ 6” × 70’ Labyrinth natural ventilators
  • Ten (10) Intake wall fans with Rain Hoods
