WATER SOFTNER-SOFIRA 50

 

HIGH-FLOW WHOLE-HOME WATER SOFTENER

A higher-flow softener built around a Keman ASB4-LCD automatic valve, a 50 L resin bed and a separate 100 L brine tank.

QUALITY + COMPLIANCE

Keman ASB4-LCD valve, 1248 FRP tank and Zhengguang resin are NSF-certified components per supplier documentation

CARE

Maintain salt level and inspect the brine tank. Check hardness and service the system annually.

BEST FIT

Larger homes and many 3-5 bathroom households after hardness and peak-demand sizing.

 

Rated for municipal tap water at 0.15-0.60 MPa. Sofira 50 reduces hardness by ion exchange; it does not replace RO drinking-water purification. Actual flow and regeneration frequency vary with hardness, pressure and household demand.

SKU: water-softener Category:
ASB4-LCD Control

The system features an ASB4-LCD automatic flow-rate-type Keman control valve for managing water softener operation.

Demand-Based Regeneration

Flow-rate control regenerates the resin according to water usage, helping manage the regeneration process based on demand.

Installation-Ready Design

The system includes a 1-inch NPT bypass with a 3/4-inch PEX adapter to support installation and connection.

Water Softening Process

The system follows a four-step water-softening and regeneration pathway:

Ca/Mg β†’ 50 L β†’ SOFT β†’ SALT

  • Hardness In (Ca/Mg): Incoming water contains hardness minerals, primarily calcium and magnesium.
  • Ion Exchange (50 L): Water passes through the resin bed, where ion exchange reduces hardness.
  • Reduced Hardness (SOFT): The treated water has reduced hardness.
  • Brine Renewal (SALT): Salt brine supports resin regeneration, restoring the resin’s capacity to remove hardness minerals.
Automatic Resin Regeneration

Automatic regeneration renews the resin bed based on programmed flow-rate control, helping maintain softening performance as water is used.
