Felt Showers in Paper Plants
In paper production, felt showers do a quiet but critical job: they continuously rinse the felts that carry and dewater the sheet. When felts stay clean, they drain better, run longer, and help the machine hold stable production.
Water temperature is a big part of that equation. Heated shower water boosts the action of detergents and dispersants, helping them dissolve faster, spread more evenly, and lift contaminants more effectively. The result is cleaner felts, fewer deposits, and a smoother, more efficient process.
How ProSonix DSI Heaters Improve Felt Shower Heating
ProSonix Direct Steam Injection (DSI) heaters are built to heat felt shower water instantly and accurately. Using direct steam injection, they deliver rapid temperature rise without lag, and hold tight control—typically within ±1 °F (±0.6 °C).
Inside the heater, steam flow modulates automatically to match demand. That means uniform heating across the full flow range, so detergent performance stays consistent and dispersions remain properly activated.
Just as important, ProSonix heaters eliminate cold spots and temperature swings that can undermine cleaning chemistry. With stable shower temperatures, mills see fewer process upsets, less chemical overfeed, and reduced risk of downtime or quality loss tied to dirty felts.
Key Benefits for Paper Mills
- More consistent paper quality
Stable shower temperature supports uniform felt cleaning and reliable dewatering, improving sheet stability and runnability. - Cleaner felts and longer felt life
Better cleaning reduces plugging and carryover, helping felts stay open and last longer between changes. - Lower total chemical usage
When detergents work as intended, mills can often reduce chemical use while achieving better cleanliness with less environmental impact. - Compact, flexible installation
ProSonix units fit tight spaces and can be installed inline or tank-mounted, depending on your shower system layout.
