1.Zero Clogging Guarantee
Self-cleaning grid-spiral structure → immune to sludge/polymer buildup (e.g., coker scrubbers).
2.Chemical Resistance
PVDF: Boiling HCl, solvents
CPVC: Hot bleach, hypochlorite (≤90°C)
PP: H2SO4 (≤60%), NaOH (any conc.)
3.Energy Efficiency
50% lower ΔP → 30% reduced pumping costs vs. ceramic packings.
Lightweight & Robust
70% lighter than metal → easy retrofit. UV/chemical stabilized.
