Universal dosing station for controlling and maintaining pH (hydrogen ion concentration) of the swimming pool water.

For pools of volume:

  • from 1 to 250 cubic meters - private;
  • from 1 to 150 cubic meters - public.


A high-precision algorithm of dosing logic for the pH corrector allows achieving the best parameters, maintaining the required concentration.

One galvanically separated input allows significantly increasing the accuracy of measurements of pH and, consequently, the subsequent dosing control.

A single silencio-peristaltic pump with a performance of up to 2.2 l/h (optional 1.5 l/h).

The ability to connect an unlimited number of duplicate dosing pumps with a performance up to 2.2 l/h.

Built-in overdosing protection - a regulated setting of the maximum allowable daily dosing volume of chemical substances required to achieve the required concentration in the pool water. When the upper limit is reached, the station stops the dosing process until the current days are completed. This protection prevents overdosing in case of a measuring sensor failure.

The ability to connect a chemical level sensor in the canister. The chemical level sensor prevents water runoff in the dosing line, which prevents chloride crystallization. The pump stops when the chemical level in the canister is monitored (suction node ACON).

The station includes three flow control options:

  • Connection to the station with 220 V and the filter pumping station;
  • Connection of the filtration control block;
  • Connection of the flow sensor.

The ability to measure and indicate the temperature of the water in the pool with the help of a temperature sensor (purchased separately).
Accumulation of statistics on emergency situations, used chemical substances, and control parameters.


An informative two-line display with an intuitive interface in Russian allows you to set up the station's operation as easily as possible.

Division into user and service settings, protected by a password, allows you to protect the system from interference by third parties.
