Electrochemical devices destined for water treatment and for synthesis of electrochemically activated washing, disinfecting and sterilizing solutions:

	EMERALD (IZUMRUD) – a unique device, having no analogues in the world and is destined for ecologically clean and biologically valuable drinking water from city water and any fresh water source. Emerald is the Russian invention patented in 50 countries.
	STEL devices for synthesis of ecologically clean electrochemically activated washing, disinfecting and sterilizing solutions, including well-known anolyte ANK.
	AQUACHLOR devices for the on-site production of oxidants mixture solution for the purposes of water treatment and disinfection at water treatment plants, wastewater treatment plants, swimming pools etc.

The unique electrochemical devices, patented in more than 50 countries and manufactured by “Scientific-and-production association “Ekran”, JSC and by “LET”, LLC, have no analogues. However, there exist companies that manufacture devices of their own under the name of STEL or its derivations thereby violating intellectual property rights of the technology devisers. Those who purchase the said devices from the companies-infringers do not only get low-quality products, but do risk their health. For more detailed information…

If you take care of your health, you should purchase only the original STEL and EMERALD devices manufactured by “Scientific-and-production association “Ekran”, JSC and from “LET”, LLC.
