Baghouse Replacement Project

Beginning as a competitive bid against a top-competitor, JDI won this project by being more detail-driven. Our ability to price their baghouse and industrial sheet metal services fairly and to properly define the scope of work required, impressed this client to choose us over anyone else.

The intention of this project for this manufacturer was to convert their baghouse-system to a blower-driven system, which required us to fabricate and install structural steel on their roof. This steel would allow the roof to support 100’s of linear feet of rooftop ductwork, some sections being up to 26″ in diameter.

We had to build raised duct supports on top of roof penetrations. Each penetration had to be repaired by a certified roofer that we contracted. Nordfab ductwork was installed on top of these duct supports to connect the baghouse with cyclones in a penthouse that was over 450′ away on the other side of the plant.

The customer purchased a replacement baghouse with twice the capacity of the legacy system. JDI installed this new baghouse with the foundation and control valves while the legacy system was still in place.

This project took place over four months, followed by a series of three shutdowns. During each shutdown old antiquated equipment was removed and new cyclones were installed. The new equipment install was phased to minimize production downtime.

To demolish and install each piece of equipment, a 400-ton crane was utilized to remove a section of the penthouse roofing, and pick the old equipment and place the new in its place.

We followed the customer’s critical lift procedure so that everything was delivered safe and sound. The critical lifts were also done under an adjacent airports flight pattern, which required daily coordination between our crane operators and their control tower to stay clear of flight paths.

After each critical lift, JDI completed the shutdown by connecting each piece of equipment by connecting the Nordfab ductwork and added a series of dampers and controls. Next, we connected each piece of equipment to their production control modules.

Finally, JDI demolished and removed the legacy baghouse and connected the new system to the new baghouse. The client is highly satisfied with JDI’s work and is planning the next few projects for other engineers at the same plant.

• 1300′ of Nordfab Ductwork Installation
• Supplied and Installed Barometric Dampers for Ductwork
• Erected & Installed 2400 cubic-foot baghouse
• Fabricated & Installed Steel Supports for Large Diameter Ductwork
• Removed & Replaced Eight Cyclones
• Added Pneumatic Slide-Gate to Six Main Cyclones
• Installed 350 LFT of Compressed Air Lines
• Performed Thirteen Critical Lifts w/400-ton Crane
• Fabricated & Installed approximately 4000 LF of Structural Steel Reinforcement
• Created 32 cubic-yard Concrete Foundation for Baghouse

The JDI team members who worked on this led the project to completion, not just through hard work and expertise, but also by establishing relationships with the manufacturer’s managers and employees at the company.

The client refers us for baghouse & industrial sheet metal services regularly because of this project’s success.
