Ventilation Issues:
The facility had numerous heat generating equipment, mostly ovens, and lacked adequate fresh air into the buildings. Two existing 56” direct drive roof fans were not in use as the noise generated by the fans was too much to tolerate for anyone working in the building.
Solution:
To remove the heat, eleven 62” roof fans were installed and wall lovers were also provided wherever space allowed. Openings in the roof were designed to accommodate the weight of the new roof fans and metal frames were installed as were custom made roof curbs to accept the new fans. The existing direct drive fans were removed and new fans were installed in their place. Noise from the fans was no longer an issue and the sound level was kept below 70 decibels. The project was completed turnkey with the customer handling the electrical, we provided the starters.
Results:
"I want to thank you and your team for working safely. We had very little, to no missed production due to this activity. I appreciate you working around our chaotic environment.”
