Research and Production Association , the renowned leader in the development of the state-of-the-art medical equipment, developed and produces the unique STEL devices for the synthesis of ecologically friendly and highly effective washing, disinfecting and sterilizing solutions.

  The STEL device operation bases on the electrochemical transformation of a sodium chloride solution with low mineralization into the ANC activated neutral anolyte solution, a metastable solution with low concentration of biocidal agents.

  Basic advantages of the ANC anolyte with respect to stable biocidal substances.

  Unlike routinely used disinfecting and sterilizing solutions, such as glutaric aldehyde, formaldehyde, chloramine, sodium hypochlorite, dichlorizocyanurates, peracetic acid, quaternary ammonium compounds (QAC), heavy metal compounds and other synthetic biocidal substances, active ingredients of the ANC anolyte do not belong to xenobiotic substances and produce no harmful effect on man and warm-blooded animals. These substances are inorganic short-lived peroxide compounds which are normally synthesized in the human body and that of warm-blooded animals by special electrochemically active cell enzymes and participate in the processes of neutralization of harmful and alien substances in the body (phagocytosis).

  A metastable peroxide mixture, formed in the course of bio-electrochemical reactions in the human body and that of warm-blooded animals, is the most efficient of all known means of eradicating microorganisms, since it possesses a variety of spontaneously realized abilities to irreversibly disturb vitally important functions of microorganism bio-polymers at the level of electron transfer reactions. It is proved by the observation that during the evolution of the highest life forms, tens of thousands years long, the microorganisms failed to develop resistance to such metastable chemical systems.

  The STEL devices are automatic; they are reliable, simple and handy and do not require operator's control. They work by the pre-established program producing solutions with highly stable parameters. The operation mode features high dynamics: production of a solution with given properties begins 10 seconds after switching on the facility. The STEL device needs for its operation a pressure water source, common salt of any quality and an electric power source. Besides, a small amount of the hydrochloric, citric or acetic acid solution (about 1 liter of the 3% acid per week for a RFE reactor containing 10 FEM-3 elements) for regular cleaning of the electrochemical reactor's cathode chamber from sediments of alkali-earth metal hydroxides. The STEL device, if necessary, can be equipped by a special portable device for the electrochemical synthesis of hydrochloric acid from the sodium chloride solution for cleaning the reactor's cathode chamber. If a water supply system is absent in the site of the STEL device operation it can be substituted by a reservoir equipped with a pump and filled with fresh water of any quality (from a river or a lake). The STEL devices are ecologically friendly allowing to abandon the use of washing, disinfecting and sterilizing agents.

  The STEL devices are indispensable in remote locations, military garrisons and frontier posts and in emergency situations, whenever the urgent supply of large amounts of disinfecting agents is necessary.

  Automated STEL-A installations. Currently the growing interest is observed of healthcare institutions in the electrochemically activated sterilizing, washing and disinfecting solutions. It is explained by their ecological safety, absence of agents toxic for human beings and warm-blooded animals, high microbiocidal activity and, besides, by rather low cost and easy production and application. At the same time the healthcare institutions show the strongest interest in the STEL-device-based automated installations (STEL-A installations) which are able to supply any required amount of the activated solutions. Besides the STEL device, such installations include hydraulic systems providing connection to the water supply system via a pressure reducer, an electromagnetic valve, a filter for capturing mechanical suspended matters, and capacities for the activated solutions with floating level controller which is electrically connected with the starter of the STEL device. The STEL-A installation also includes systems for storage of the acidic solution, for the automatic washing of the electrochemical reactor and for the consequent collection of the waste acidic solution. In cases of low pressure in the water supply system, the STEL-A installation includes additional capacity for water equipped with a pump which with the installation's facilities by the automatic control system. The installation provides permanent supply of the required volume (regularly from 200 to 2,000 liters) of the ready-to-use electrochemically activated sterilizing, disinfecting and washing solution to a healthcare institution.

  The STEL-device ancillary systems for the application of the ANC electrochemically activated anolyte in the form of fog. The Association in collaboration with the researchers and experts from St.Petersburg produces the STEL devices with the installed centrifugal fog generators. Such a mode of the anolyte application proves to be very effective for treatment of premises in healthcare institutions, including surgery units, cattle-breeding farms, storehouses for fruits and vegetables stored in containers. The conformity certificates are available.

  The STEL-device ancillary systems for the prevention of the dentistry and ophthalmologic instruments corrosion during their treatment by the electrochemically activated ANC anolyte solution. Medical instruments made of carbon steel and, in particular, dentistry instruments are subject to corrosion when they are treated by the electrochemically activated ANC neutral anolyte solution. To prevent corrosion, the STEL devices may be equipped with special flasks with portable systems of electrochemical or galvanic protection. The flasks are made having either standard or custom-ordered dimensions.
