The most extensively used backflushable pleated filter in power plant condensate.
- Backflushable pleated filter designed specifically for use in power plants
- The Hydro-Guard PPB-R is used in condensate applications with resin precoat
- Constructed with the highest purity materials (no fillers, talcs, TiO2 or surfactants) for minimal rinse-up time
- Surface area exceeds that of conventional condensate filters by a 20:1 ratio for lower pressure drops, increased filter life and longer backflush cycles
- Eliminates costs associated with use and disposal of powdered resins
- Iron oxide and suspended copper are typically reduced by 98%
- Constructed to retain the resin precoat on the surface for efficient backflushing and particle removal.
