    ECOCHLOR (AQUATRON-25) is a class of devices for electrochemical synthesis of gaseous chlorine and concentrated solution of caustic soda. The AQUATRON-25 device are compact safe modular chlor-caustic plants that have no analogues in the world. The capacity of a single module varies from 1 to 10 kg / h in gaseous chlorine.

    Technological schemes of electrochemical synthesis processes in the AQUATRON-20 and AQUATRON-25 devices are distinguished by systems at the outlet of chlorine from the anode circuit, where the pressure can be in the range from 1 to 6 atm. In the AQUATRON-25 devices, unlike the AQUATRON-20 devices, arrangements are required for heating the chlorine before the pressure stabilizer and the moisture extraction system before feeding to consumers. The AQUATRON-25 devices are manufactured in accordance with the patents of the Russian Federation No. 2270885, 2350692.

    ECOCHLOR-003 device, model of 2012.

    The class of electrochemical systems AQUATRON-25 until 2016 was represented by a model range of ECOCHLOR devices with a maximum chlorine capacity of 500 g / h. The use of electrochemical elements with high volumetric current density in ECOCHLOR devices allowed to increase the productivity of these plants by three times with chlorine and caustic soda, while maintaining the previous energy consumption (by reducing the voltage on electrochemical modular elements) and with constant overall dimensions of the device, and also allowed to create modular ECOCHLOR devices with a single chlorine capacity of up to 10 kg/h.

    ECOCHLOR device is a compact, environmentally friendly, economical, high-performance module for the production of chlorine and caustic soda solution at the site of their consumption. The ECOCHLOR-003 device is a modular device with dimensions 60 × 60 × 180 cm with a capacity of 3 kg / h of gaseous chlorine and electric power consumed of 9.0-9.6 kWh. The ECOCHLOR-003 device uses the latest Bakhir modules MB-1600 with a capacity of 1600 g / h each. Such devices allow the creation of safe, energy efficient and environmentally friendly plants for the production of chlorine and caustic soda.


    Total replacement of chlorine plants to ecologically clean manufactures at places of use of chlorine and hydrate of sodium, that allows to exclude system and appropriate equipment for chlorine dehydration, transportation and storage as well as special safety systems under chlorine usage.
