The Excalibur 90K Duplex Water Softener (1.0″ EE Metered) is a commercial-grade, fully automatic twin-tank softening system engineered to deliver continuous soft water with high reliability and minimal service interruption. Ideal for homes, light commercial facilities, cottages, offices, and other installations with variable or heavy water use, this duplex system features twin resin tanks that alternate service and regeneration to ensure uninterrupted soft water supply — even during regeneration.
Key Features & Benefits
- 90,000-grain total softening capacity (grains of hardness removed before regeneration) for generous service between regenerations.
- Duplex (twin tank) design: One tank softens water while the other regenerates, delivering continuous soft water without downtime.
- 1.0″ Electronic Electronic (EE) metered control valve: Regeneration is initiated based on actual water usage (metered), reducing salt and water waste.
- Multiple regen initiation options: Metered immediate, metered delayed, time-clock delayed, or pressure differential.
- Fully automatic operation: Once programmed, the system monitors usage and regenerates only when needed — optimizing salt, water, and resin life.
- High flow capability: Designed for commercial and larger residential service with smooth flow and minimal pressure loss.
- Resin and distributor support bed: Engineered for efficient ion exchange and low pressure drop through the softening resin.
Compatibility
The Excalibur 90K Duplex Softener is suitable for a wide range of applications involving hard water (calcium and magnesium) that can cause scaling, spot-ting, soap inefficiency, and appliance wear. It can be installed upstream of water-using equipment, including:
- Homes and cottages
- Offices, commercial spaces, and light industrial sites
- Pre-treatment for water heaters, reverse osmosis systems, and boilers
- Any application requiring continuous soft water even during regeneration cycles
- This model operates with standard 1.0″ plumbing connections and is compatible with typical salt types (sodium or potassium).
Maintenance
- Salt refill: Regularly add water softening salt to the brine tank when low — frequency depends on water hardness, usage, and settings.
- Resin care: Periodic inspection and potential resin replacement may be required over the long term for peak ion-exchange performance.
- Valve and meter checks: The EE metered control should be checked to ensure proper usage tracking and timely regeneration.
- Regeneration efficiency: Adjust regeneration parameters (e.g., delayed vs immediate metered) to optimize salt and water usage.
Why Choose This System
The Excalibur 90K Duplex Water Softener is designed for demanding soft water needs where service continuity and efficient regeneration matter. Its twin-tank alternating design means you never lose soft water while one tank is cleaning, and its electronic metered control valve ensures resources are used only when necessary — making it a cost-effective and reliable choice for robust residential and light commercial water treatment.
