Fiberweb Equipment Relocation
Old Hickory, Tennessee
Owner: Fiberweb, Inc.
Contract Amount: $800,000
The Fiberweb Equipment Relocation – Horizon Pilot Line project involved the relocation of the research and development line from Simpsonville, South Carolina, to Old Hickory, Tennessee. The work included disconnecting, packing, and transporting the process equipment, utility lines, and all associated accessories. Once the items arrived in Old Hickory, they were unpacked, cleaned, painted, and inspected before the installation.
The process equipment is located on a four-level mezzanine (17,000 sq ft), where the process starts at the fourth level and feeds down to the lower levels. The product starts out as plastic pellets which are heated through a Dow Therm system to 600̊ F and then extruded to a fiber. The fiber is moved through the line to a lay-down table where it is moved through water and steam before it is baked to a sheet. This product is used for anything from dryer sheets to house wrap.
The utilities, which were installed to supply this process, include 10 to 15 psi steam, steam condensate, chilled water supply and return, compressed air, nitrogen, Dow Therm heated compressed air, natural gas, and hot oil.
To condition the area of the process, there is a 20,000 cfm exhaust fan with a hood and associated duct to remove the excess steam, as well as a 50-ton DX unit supplying conditioned air to four mezzanine levels. The exhaust for the process lay-down tables includes two 100 hp exhaust fans and one 150 hp exhaust fan vented to the outside.
