Shower nozzle protection
Nozzles with sub-millimetre orifices block on fibre bundles and scale, and the failure is visible in the sheet immediately.
Heavy Industry · Industry
White water, shower and coating filtration on machines where a nozzle blockage becomes a sheet break within minutes.
- White water train throughput
- 2,400 m³/h
- Shower water cut point
- 60 µm
- Fibre recovery improvement
- 8%
The constraint
Machine uptime protected sheet by sheet.
Paper machines run at extreme speed with almost no tolerance for interruption. A blocked shower nozzle creates a streak, a streak becomes a break, and a break costs an hour of production.
Standards we work to
- TAPPI Standards
- ISO 16890
- EN 14491
- ISO 9001
- IED 2010/75/EU
Fibre and filler recovery
Solids in white water represent recoverable raw material, so filtration is a yield mechanism as well as a protection one.
Stickies and pitch
Adhesive contaminants from recycled furnish coat surfaces and defeat conventional cleaning.
High volumetric flows
White water systems circulate enormous volumes, making pressure drop a first-order energy cost.
