Challenge
To design, build, install and commission a steam extraction system onto an existing production process. We had to ensure the fabric being steamed still received the required moisture but any excess was removed from the area to an external point ducted through the roof.
Solution
We provided detailed drawings and specification for the machine modifications and once approved, we carried out the installation during a one-week shutdown period to avoid any production disruption.
The system comprised of two purpose-made steam extract hoods manufactured from 304 st/st with a fully tig welded construction, complete with steam extract slot, 20mm drain socket, mounting brackets and flanged edge for duct work connection.
Duct work was manufactured from light gauge galvanized mild steel sheet, complete with 6mm jointing edge, silicone seals and galvanized tension clips. We included for a st/st square to round adapter to connect to the existing floor mounted centrifugal fan unit. The adapter was fully welded, complete with a drain socket and range of 125 dia galvanized duct work to couple to the branch on the new 300dia vertical riser.
The duct work from either side of the machine terminated in a trouser section that would couple to a purpose-made, hot dip galvanized, bifurcated, extract fan. The fan was complete with mounting flanges, aluminium variable pitch impellor running on the extended shaft of a 2 pole 3 phase electric motor complete with invertor speed controller. The fan discharge to atmosphere via the exiting galvanized spiral stack, protruding through the roof over the machine.
Result
The client now has a system that improves production quality, is variable for different products and ensures no build-up of moisture around any other components.
