Boiler Feedwater Softening Resin (Strong Acid Cation, Na-Form)
Strong acid cation resin in sodium form for boiler feedwater softening, removing hardness to < 0.1 mg/L CaCO₃ for LP and HP boiler protection against scale.
Technical Specifications

Applications
- Low-pressure boiler feedwater softening
- High-pressure boiler makeup water treatment
- Steam generator scale prevention
- Industrial hot water system conditioning
- District heating system water softening
Key Features
- Reduces hardness to < 0.1 mg/L — protects boiler tubes from CaCO₃ and CaSO₄ scale
- High capacity ≥ 2.0 meq/mL — long service run between regenerations
- Salt brine regenerable — low chemical cost versus RO alternatives
- Temperature-stable to 120°C — suitable for high-pressure boiler systems
