Excalibur 120K Duplex Commercial Water Softener, 1.25in EE Metered

Description

IN STORE PICKUP ONLY

The Excalibur 120 K Duplex Commercial Water Softener with 1.25″ connectors and electronic (EE) metered control is a high-capacity, fully automatic duplex softening system designed for continuous service and high-reliability performance in commercial environments. Built to deliver softened water consistently even during heavy use periods, this system uses two alternating softener vessels so that one is always in service while the other regenerates — ensuring uninterrupted soft water supply.

Key Features

• Duplex configuration: Two vessels work in tandem — one in service while the other regenerates — for 24-hour soft water availability without downtime during regeneration.
• 120,000 grain system capacity: Designed for moderate-to-high commercial water softening needs, effectively reducing hard water minerals (calcium & magnesium).
• 1.25″ control valve connections (EE metered): Standard commercial plumbing size with electronic flow meter that measures real-water usage to initiate regeneration precisely.
• Demand-initiated regeneration: Regeneration can be initiated using multiple modes including metered immediate, metered delayed, time clock, or pressure differential, maximizing efficiency and minimizing wasted water and salt.
• Motorized alternating valve (MAV): Automatically switches between vessels so soft water remains available even during regeneration cycles.
• Fully automatic operation: Electronic control manages metering, regeneration profiling, and service cycles for minimal manual intervention.

Performance & Specifications

While exact model numbers within this class (e.g., EWS SD15120) may vary, typical specifications for a Duplex 120 K system with 1.25″ EE metered valves include:

• Softening Capacity: ~120,000 grains (per system at 15 lbs/ft³ resin)
• Duplex System Max Capacity: ~240,000 grains total when both vessels are considered (service + stand-by)
• Valve Size: 1.25″ with electronic metered control
• Flow: Up to ~29 GPM (varies by specific model) under normal operating pressure
• Regeneration Control: Internal electronic flow meter with Hall Effect sensor measuring ~0.25–34 GPM
• Operating Pressure: Typically ~40–125 psi
• Operating Temperature: ~40–110 °F (4–43 °C)
• Automatic Regeneration Options: Metered immediate, metered delayed, time clock delayed, pressure differential
• Duplex Alternating Valve: Full-ported motorized unit ensures one tank remains online while the other regenerates.

Note: Specific dimensions, shipping weight, and exact flow ratings depend on the chosen model (for example, SD12560, SD12590, etc.). Standard datasheets for this series show mineral tank sizes, bed depths, and brine tank details.

How It Works

In a duplex softener, two separate mineral tanks each contain ion-exchange resin that removes hardness minerals. The system’s electronic metered control head tracks actual water usage and triggers regeneration only when needed — conserving salt and water. As one tank is online treating water, the other can regenerate, so softened water flows continuously without interruption.

Ideal Applications

This commercial duplex softener is well-suited for environments requiring consistent soft water without downtime, such as:

• Commercial kitchens & foodservice
• Apartment complexes and multi-unit dwellings
• Laundry facilities and hotels
• Office buildings & schools
• Industrial operations with moderate flow requirements
• Pre-treatment for boilers, heat exchangers, and RO systems

Benefits

• Uninterrupted soft water: Duplex configuration ensures soft water availability 24/7 during regeneration cycles.
• Efficient regeneration: Demand-initiated metered control maximizes efficiency, saving salt and water.
• Robust commercial performance: 120 K grains of capacity handles heavier usage patterns.
• Automatic operation: Electronic controls reduce maintenance requirements and improve service life.

Maintenance & Care

• Salt replenishment: Keep the brine tank filled with quality softening salt to ensure consistent regeneration.
• Periodic resin inspection: Over time and heavy use, resin may need professional replacement or cleaning.
• Valve service: Electronic controls and MAV units should be inspected periodically for wear and sensor calibration.
