Water Softener for Hardness Removal – 14×65 FRP Vessel – Automatic Regeneration

The 14×65 water softener for hardness removal uses Polymex cation-exchange resin to reduce calcium and magnesium hardness. This helps limit new hardness-related scale in pipework, geysers and suitable water-using equipment.

The system combines an 14×65 FRP vessel, Runxin F63C3 automatic metered softener valve, softening resin and a brine tank. Salt-brine regeneration restores the resin for continued use.

Free salt included: One bag of softener salt is included, subject to availability.

Key Features & Benefits

• Hardness reduction: Ion exchange targets calcium and magnesium responsible for hard water.
• Automatic metered control: The F63C3 initiates regeneration according to the configured treatment capacity, with delayed or immediate modes available.
• Regenerable resin: Suitable softener salt is used to restore the resin’s working capacity.
• Brine tank included: Provides the separate salt-and-water reservoir used during regeneration.
• FRP vessel: Corrosion-resistant construction houses the resin bed.

Applications

• Domestic and commercial installations with measured hard water.
• Point-of-entry softening, sized for the household or site’s peak demand.
• Reverse-osmosis pre-treatment or compatible process equipment requiring hardness reduction.

Technical Specifications

• Product code: H2OW24
• Vessel size designation: 14×65; nominal vessel designation, not the installed height including the valve.
• Vessel material: Fibreglass-reinforced plastic (FRP).
• Treatment media: Polymex cation-exchange softening resin
• Head / control: Runxin F63C3 automatic metered softener valve
• Regenerant: Water-softener salt (sodium chloride).
• System capacity: Determined by the actual resin loading, inlet hardness, required outlet hardness and salt dose; the valve rating is not the complete system’s treatment rating.
• Valve model reference: F63C3 / 63604; metered down-flow regeneration.

What’s Included

• Vessel: 1 × 14×65 FRP vessel.
• Control valve: 1 × Runxin F63C3 automatic metered softener valve.
• Resin: Polymex cation softening resin for this product configuration.
• Brine tank: 1 × brine tank.
• Salt: 1 free bag of softener salt, subject to availability.

Installation & Use

• Sizing and commissioning: Set treatment capacity, salt dose, stage times and regeneration interval from the water analysis and actual resin loading.
• Pre-treatment: Provide sediment and iron/manganese treatment where necessary to protect the resin.
• Installation: Provide suitable pipework, isolation/bypass arrangements and a drain for regeneration water. Any feed pump has its own power and installation requirements.
• Resin loading: Allow the specified expansion space for backwashing; do not fill the vessel completely with resin.
• Routine care: Keep the brine tank supplied with suitable salt and test treated-water hardness to confirm performance.
• Regeneration control: Metered delayed mode starts at the programmed regeneration time after capacity is used; immediate mode starts when capacity is exhausted. Intelligent modes use configured resin volume and water hardness.
• Day override: The F63C3 also supports a maximum-day interval alongside metered operation. Follow the F63C3 sections of the shared manual when configuring the controller.
• Manual initiation: A regeneration cycle can also be started from the control panel when required.

Important Information

• Water supply during regeneration: Allow for an interruption to normal softened-water service during regeneration of this single-vessel system.
• Treatment scope: Softening reduces hardness; it does not disinfect water or replace treatment for other contaminants.
• Existing scale: The purpose is to reduce further hardness-related scale formation, rather than promise immediate removal of established deposits.
• Safe servicing: Isolate and depressurise before servicing. Follow the vessel, valve and resin instructions.
