RAPIDSOFT® and RAPIDSOFT® PLUS provide salt-free alternatives to conventional ion-exchange water softeners for residential and commercial scale-prevention applications.
RAPIDSOFT® uses FILTERSORB® SP3 nucleation-assisted crystallization technology to condition temporary carbonate hardness without removing calcium and magnesium from the water. RAPIDSOFT® PLUS combines FILTERSORB® SP3 scale prevention with TRAPPSORB®-based water conditioning for applications requiring an additional corrosion-control and magnesium-conditioning stage. Both systems operate without salt regeneration, brine discharge, backwashing or electrical control valves.
Designed for point-of-entry and equipment-protection applications where temporary carbonate hardness creates scale on plumbing, heating surfaces, fixtures and water-using appliances.
Scale prevention for compatible centralized hot-water systems, fixtures and building services.
Water conditioning for compatible cleaning, rinsing and food-service equipment.
Applications include cooling towers, evaporators and humidifiers following application-specific water analysis.
Protection for coffee brewers, tea brewers and espresso machines.
Scale prevention for steam ovens and other compatible water-heated equipment.
Residential applications including water heaters, tankless water heaters, bathrooms and showers.
FILTERSORB® SP3 provides nucleation sites that transform temporary carbonate-hardness components into microscopic calcium-carbonate crystals.
The system does not remove calcium and magnesium through ion exchange, allowing these naturally occurring minerals to remain measurable in the treated water.
No salt, brine tank, electrical regeneration control, backwash cycle or regeneration wastewater is required.
RAPIDSOFT® PLUS combines FILTERSORB® SP3 with TRAPPSORB® for additional conditioning. Published corrosion-control and magnesium-release performance must be supported by validated data.
Detailed feature comparison between salt-free nucleation-assisted crystallization and traditional ion-exchange softening.
| Function | RAPIDSOFT® | Salt-based Softener |
|---|---|---|
| Primary purpose | Scale prevention | Hardness removal |
| Main process | Nucleation-assisted crystallization | Ion exchange |
| Calcium and magnesium | Remain in the water | Removed or substantially reduced |
| Sodium or potassium addition | No ion-exchange addition | Replaces hardness ions |
| Salt requirement | No | Yes |
| Brine tank | No | Yes |
| Regeneration | No | Required |
| Backwashing | Not normally required | Normally required |
| Regeneration wastewater | None | Produced during regeneration |
| Electricity | Not normally required | Often required for control valve |
| Measured hardness after treatment | Generally remains | Reduced |
| Soft-water feel | No conventional softened-water feel | Conventional soft-water feel |
RAPIDSOFT® controls the behavior of temporary carbonate hardness rather than removing hardness minerals from the water.
