Ecosoft FK 1252 CE Twin filter is intended for complex water treatment and reduction of iron, manganese, hardness, ammonium and organic matter.

The filter is commonly used in cottages, restaurants, laundries, car washes, breweries, bakeries, water-heating and steam-powered boiler plants.

The filter represents a vessel containing Ecomix® advanced softening media, a multifunctional control valve that provides and manages the entire operation and a brine tank for system regeneration.

Model features

The filter of complex purifying gives significant savings on the purchase and maintenance of the home water treatment system. One filter Ecosoft FK 1254 CE Twin replaces several specialized units. The system operates continuously in the automatic mode, and its maintenance is limited only by the timely addition salt tablets.

Key advantages

  • Eliminate the yellow shade of water.

  • Fully automatic and noise-free.

  • Cost-effective salt consumption and low volume of discharge.

  • Durable and efficient operation during no less than 7 years.

  • Quality guaranteed by the international CE and ISO certificates.


Device and filter operation

The system consists of two main modules - two cylinders with filter media and a brine tank. The cylinders are made of corrosion resistant polymer composite material. Inside the filter is an Ecomix® media which consists of several components.

Each component of the filling is designed to neutralize or remove a certain kind of harmful impurities. As a result, integrated water filtration is carried out in one stage. Purified water has good taste characteristics and can be used for any household needs. It is completely safe for skin and hair, and also does not cause scaling on the heating elements of the devices.


The service life of the filter media is 7-10 years. This is possible due to the regenerative ability of the Ecomix®. The recovery of the filtering properties of the media is carried out by regeneration with tableted salt solution. As well as water purification, the regeneration process is carried out automatically.

After exhaustion of filter  media resource operating valve transfers one balloon of the filter to the regeneration mode and puts into operation the second. Regeneration takes place with purified water, which is supplied from the working part of the filter, and takes place in 5 stages, which are clearly programmed and carried out by the valve independently.

Control Automation

Electromechanical valve CE (Clack-Ecosoft) is used to control the filter operations. It has a whole list of advantages over older control valve models. Among the advantages of the controller - a multilingual menu, non-volatile memory and a multi-line LCD display with night illumination function.

Who is the user?

The system of complex purifying Ecosoft FK 1252 CE Twin is best fit for cleaning water in cottages, restaurants, laundries, car washes, breweries, bakeries, hot water boilers and steam boilers.

The filter is connected to the cold water supply system, effectively purifies the water and independently controls all the processes of its work.
Pre-purified from mechanical impurities water enters the filter vessel filled with Ecomix® filter media. The media consists of five components that successively trap iron, manganese, organic impurities and hardness salts. Purified water through the central pipe of the case is supplied to the consumer.

When the resource of the filter media ends, the filter independently goes on regeneration, but only at a time when water consumption is minimal, so it won't deprive you of access to purified water. In addition, the control valve remembers the intensity of your water consumption at different times and is adapted so that clean water is available even at peak consumption, for example, on weekends.

Regeneration takes place in 5 stages

  • Flushing with back flow of water. At the same time, iron and manganese compounds are washed out of the filter media.

  • The brine solution is fed from the tank into the filter vessel, passes through the Ecomix® and washes away hardness salts and organic matter from it. Impurities with the remnants of the solution are discharged into the sewage.
  • Short backwash. Once again, loosens the load and washes away the remnants of the salt solution.
  • Flush the Ecomix® with a direct stream of water to lay layers of media in the desired order.
  • Fill the brine tank with water to dissolve the tableted salt and prepare the solution for the next regeneration.

After that, the system can purify water again.

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.
