EJ USA

Natural ventilators and adiabatic natural cooling units
Labyrinth vent
low-profile natural ventilator

EJ USA foundry needed to update its ventilation to improve employee morale and retention. During the summer, indoor temperatures rose to 110°F+, making work conditions inhospitable. Fans were not a feasible solution because they stirred up the silica and posed different health problems. After attending a demonstration at the Moffitt factory, and getting an on-site design consultation, EJ management knew Moffitt could help them find a ventilation solution.

Moffitt installed four (4) low-profile vents over the molding area to provide an exhaust point for the warm air. This allowed the warm air to vent immediately lowered internal temperatures. Six (6) adiabatic cooling units were then installed above the finishing area. With the stifling air removed by the low-profile vents the natural cooling units were now able to introduce cool, below-ambient air toward the floor

After both phases were complete temperatures recorded at floor level were notably more comfortable, up to 20° cooler in some locations. Employees have commented on the improvement in temperature and morale has already improved.

Project Summary

  • Two (2) 10.5’ x 20’ low-profile ventilators
  • Six (6) adiabatic natural cooling units.
