Vessel filter KDF85 Clack valve WS1 vessel 14X52, ref. CLACK-WS1.25TC-KDF85-125

Overview

Vessel filter filled with KDF 85 redox medium (copper-zinc), on a Clack valve (ref. CLACK-WS1.25TC-KDF85-125). Vessel 14X52. Valve WS1. This filtration station provides removal of iron and hydrogen sulphide, at point of entry to protect the whole installation. Delivered ready to install (filled vessel + valve + distribution), it treats mains, well or borehole water.

Filtration principle

KDF 85, a copper-zinc alloy, is optimised for removing iron and hydrogen sulphide (H2S, rotten-egg odour) from well water. By redox reaction it oxidises these compounds into particles retained in the bed and flushed out during backwash, without chemical reagent, while limiting bacteria and scale.

KDF85 media

The vessel is filled with KDF 85 redox medium (copper-zinc) on a gravel/silex support bed that distributes the water and retains fines. Media volume: 125KG. Depending on the medium, the bed is backwashed (carbon/Ecomix) or topped up as it is consumed (calcite/Corosex/Everzit), to maintain performance over time.

Valve & operation

The WS1 valve automatically drives the cycles: service (filtration), backwash, rinse and return to service (and salt regeneration for Ecomix). Triggering is timed or metered per model; a built-in bypass isolates the filter without cutting the water.

Sizing & installation

Choose the size (vessel 14X52) according to peak flow and water quality. Provide a drain for backwash and a power supply for the valve. Install frost-free, on a flat floor; an upstream sediment pre-filter is recommended to protect the medium.

Savings & ecology

Treating water at point of entry protects the whole installation: less corrosion (pH correction), more pleasant water (carbon) and preserved equipment, so fewer replacements and less maintenance. Backwash uses only water (and salt for Ecomix), without polluting additives: an effective, resource-respecting treatment.

Choosing right

To choose well, have your water analysed (pH, alkalinity, chlorine, iron) and estimate peak flow. The medium is chosen by need: carbon (taste/chlorine), calcite/Corosex/Everzit (pH correction), Ecomix (multi-parameter). The DIMM team helps you size vessel, valve and pre-treatment.

Key specifications

DIMM service & support

DIMM designs, assembles and ships turnkey vessel filters (Aquacarb/Carbsorb carbon, Calcite/Corosex/Everzit pH correction, Ecomix multi-layer) on Clack valves, plus the hoses and accessories. Our teams analyse your water, size vessel and valve and advise the right medium and pre-treatment. Every item is identified by its article code, with manufacturer's warranty, parts and refill media available. From advice to commissioning, we support installers and homeowners, from sizing the vessel and valve to the choice of medium and maintenance follow-up, with a stock of refill media and parts immediately available.

Good to know

The medium is chosen from the water analysis: carbon for taste and chlorine, calcite/Corosex to raise an aggressive pH, Ecomix for multi-problem well water. Provide the backwash (sufficient flow and drain) and, for pH-correction media, periodic checking and topping-up of the level as they are consumed. An upstream sediment pre-filter protects the medium and spaces out backwashes, while a regular water analysis lets you fine-tune the valve setting.

Applications

These vessel filters are installed at point of entry (whole-house or building protection), in residential as well as tertiary and agricultural settings. Depending on the medium, they polish taste, correct pH or treat several parameters. They combine with a sediment pre-filter and, if needed, aeration, for healthy water and protected plumbing year-round.

Warranty & re-supply

Station assembled and distributed by DIMM, identified by its Business Central article code for reliable ordering and easy re-supply. It carries the manufacturer's warranty; the valve, vessel, refill media and compatible hoses remain available in the catalogue to support the installation throughout its service life.
