OXYMED – devices for producing antimicrobial solution with high specific content of oxidants – ANK anolyte. OXYMED devices produce ANK anolyte on a large scale (from 200 to 1000 liters per hour for one device). OXYMED devices endure continuous long-term operation with short breaks (not exceeding 30 minutes in 24 hours) for cleaning electrochemical reactors. A fundamental distinction of OXYMED–range devices from AQUATRON- and STEL-type devices is combination in one device of RPE-03 reactors made up of FEM-3 modules and RPE-07 reactors made up of FEM-7 modules. RPE-03 reactors are meant for electrochemical treatment of water with the purpose of altering its structure and securing the best possible conditions of dissolving and stabilizing gaseous phase in the process of introduction of humid gaseous mixture of oxidants produced by the RPE-07 reactor from sodium chloride solution of 50-150 g/l concentration.
