A dust control system retrofit in a working plant is a different job from a greenfield install. The building is already full, the machines are already running, and nobody is going to shut the line down while the ducting goes in.

At a corrugated plant in Wisconsin, ERS planned to run the new system through existing 21-inch duct. On the first day on site that plan failed — the duct was the wrong size for what the system needed. Rather than stop, the crew walked the roof, traced a second line the plant was no longer using, confirmed it could carry the load, and rebuilt the route around it.

The work went in two phases, in March and May. Phase one put the fan, the stand and the roof penetration in place and tested rotation. Phase two set the CCM® OCT filter, the dust fan and the clean air stand, with the duct route redrawn on site a second time to clear existing ductwork and light fixtures that were not on the drawings.

None of that is unusual. Existing plants are full of things that are not on the drawings. What matters is whether the people installing the system can redesign a route on the roof on a Thursday and still hold the schedule.

This is what ERS does across the US and Canada — trim removal, scrap handling and dust collection systems, engineered as one system and installed into plants that are already running.
