Water softening filters Ecosoft FU

Water softening filter Ecosoft FU 4872CE2 (Dowex® HCRS/S)

Artnumber: FU4872CE2
€16,538
Article: FU4872CE2
OPERATING MODE: With a stop for regeneration

Ecosoft FU 4872CE2 filter is intended for water softening (reducing hardness), applicable for objects with capacity below 25 m3/h.

The filter represents a vessel filled with the Dowex ion-exchange resin, a multifunctional control valve and a brine tank for resin regeneration.

The unique control valve is a product developed by Ecosoft and produced by Clack Corporation (USA). It provides filter’s independent service, keeps constant reserve of purified water and doesn’t require any special attention.

Key advantages:

  • Fully automatic and noise-free

  • Durable and efficient operation during no less than 5 years

  • Cost-effective salt consumption and low volume of discharge

  • Quality guaranteed by the international CE and ISO certificates

Components of the filter:

  • Filter vessel

  • Clack WS2 СЕ multifunctional control valve (USA)

  • Brine tank with brine system for regeneration

  • Dowex ion-exchange resin (Dow Chemical, USA)

The filter is connected to the cold water supply. Water pre-cleaned from sediment particles enters the filter vessel filled with ion-exchange resin. Water passes through the resin layer which reduces hardness of the water. Purified water is supplied to consumer through the riser pipe of the filter vessel.

After the resin is exhausted, and can no longer absorb the ions of hardness, the control valve switches the filter to regeneration mode. For user’s convenience, the valve settings are programmed so that the filter is regenerated at the time when water is not consumed.

Regeneration of the filter media is divided into 5 clearly predetermined stages that are carried out by the valve independently. At the first stage the filter is backwashed in order to plough up the filter media and wash out sediment particles from it. Then the brine solution is supplied from the brine tank to the filter vessel to pass through resin. As a result, hardness salts are washed out, and together with the remains of solution are discharged to sewers. The third stage represents backwashing to remove the remains of regeneration solution from the riser pipe. After backwashing, washing of the resin is carried out with direct water flow (stage 4) to wash out remains of brine solution from the filter media and place the media back to the bottom of filter vessel. The last stage (5) represents filling the brine tank with water to dissolve the tablet salt, and preparation of the solution for next regeneration. After that, the filter can be again used for water purification.



Thanks to the use of a multifunctional valve, the filter does not require constant attention. The only important task connected to maintenance for customer is timely stocking of the salt. It will ensure efficient regeneration of the filter media and thus durable filter service life and water quality.

If any problem arises, the valve will inform about the problem at the display with a text message containing contact information of service center.
