RSRH-3D — 3 Tons/Hour Dual-Valve Dual Tank Water Softener

MATTIAS RSRH-3D Commercial Water Softener — Continuous Soft Water Supply, Dual-Tank Redundancy, 3 m³/h Capacity

Hard water is the hidden enemy of car wash equipment — it leaves scale on surfaces, clogs nozzles, and shortens the life of pumps and heating elements. The RSRH-3D eliminates hard water at the source, delivering a continuous supply of softened water at ≤0.03 mmol/L hardness so your equipment runs cleaner, longer.

The dual-valve, dual-tank design means one tank regenerates while the other keeps working — zero interruptions to your water supply, even during peak hours. The integrated frame keeps everything compact and service-ready, with an electronic screen display for at-a-glance monitoring and co-current resin regeneration that extends resin life and reduces salt consumption.

Built for commercial environments operating between 0–50°C, the RSRH-3D handles inlet water hardness up to 4 mmol/L and delivers treated water at 30 m/s filtration velocity. UPVC chemical-grade piping throughout ensures corrosion resistance in demanding wash bay conditions.

Key Features:

• UNINTERRUPTED SOFT WATER — Dual-tank alternating operation means softened water flows continuously — no downtime during regeneration cycles
• ULTRA-LOW OUTPUT HARDNESS — Reduces water hardness to ≤0.03 mmol/L, preventing scale buildup on nozzles, pumps, and heating elements
• ELECTRONIC SCREEN MONITORING — Digital display on the multi-way valve gives operators real-time visibility into system status without manual inspection
• CORROSION-RESISTANT PIPING — DN25/UPVC chemical-grade inlet/outlet valves, Y-strainer, and check valve stand up to the demands of commercial wash environments
• COMPACT INTEGRATED FRAME — 1650×450×1650mm footprint fits into existing equipment rooms without major infrastructure changes
• NANO RESIN, LONG SERVICE LIFE — 100L of nano-form softening resin per tank with 5–10% moisture content for high ion-exchange efficiency and durability
