Description
Simplex Water Softener with Fleck 2850NXT‑Metered Control Valve, 120,000 Grains
The Simplex® 2.0IN 120 K Water Softener is a heavy-duty, single-tank (simplex) commercial/residential water softening system engineered to deliver reliable hardness removal for larger homes, light commercial sites, or applications requiring up to 120,000 grains of softening capacity. Built with a metered control valve and high-capacity resin, this system uses proven ion-exchange technology to remove calcium and magnesium ions that cause scale buildup, improve soap efficiency, and protect plumbing and appliances.
Key Features
- 120,000 Grain Softening Capacity – Effectively reduces hardness minerals for improved water quality in moderate-to-high demand applications.
- Metered Control Valve – Regenerates based on actual water usage to conserve salt and water, rather than on a fixed schedule.
- 2.0 Inch Connection Size – Designed with a larger control valve and plumbing connections for higher flow demand typical of larger residences or commercial settings.
- Fully Automatic Operation – Digital metering and automatic regeneration make the system easy to operate with minimal manual intervention.
- Single-Tank (Simplex) Design – A cost-effective choice where uninterrupted soft water is not critical (regeneration temporarily reduces flow).
Specifications
- Capacity: 120,000 grains (approximate, dependent on resin and settings)
- Tank Setup: Single mineral tank with matching brine tank
- Control Valve Type: Metered control (e.g., Fleck 2850NXT or similar)
- Flow/Connection: 2.0 inch inlet/outlet plumbing (commercial-grade sizing)
- Automatic Regeneration: Demand-initiated based on water usage
Specific flow rate, resin volume, and pressure drop depend on the exact branded control valve and resin configuration used.
Compatibility
- Designed for point-of-entry installation, treating all water entering a building.
- Works with standard household and commercial plumbing sizes (2 inch).
- Can be paired with pre-filters (sediment, carbon) to protect the softener’s resin bed and extend performance life.
Applications
- Larger Single-Family Homes with high water usage
- Light Commercial Sites (e.g., offices, small restaurants)
- Pre-Treatment for Boilers or Water Heaters to prevent scale
- Pre-Softening for Industrial Processes requiring reduced hardness
- Laundries and Hospitality where soft water improves performance
Maintenance
- Salt Replenishment: Add softener salt to the brine tank as needed (typically every 4–8 weeks, depending on usage).
- Resin Bed Care: Resin typically lasts many years but may need cleaning if fouled by iron or organics.
- Valve Service: Periodically check and service the control valve according to manufacturer instructions.
- Regeneration Monitoring: Demand metering helps optimize regeneration frequency and reduce waste.
Regular maintenance keeps operating costs low while maximizing soft water production and equipment longevity.
Why Choose a Simplex 120 K Softener?
The Simplex 120 K Water Softener blends high capacity, automatic metered regeneration, and robust commercial-grade plumbing compatibility into a reliable softening solution for homes and light commercial sites with elevated water hardness demands. The larger 2 inch control and connections support higher flow without undue pressure loss, and metered regeneration helps reduce salt and water use over time compared to timer-based systems.
