The SESI is a non polluting electrolytic water conditioner that protects a pipe system from the formation of limescale encrustation and rust deposits (in the case of steel pipes) without the use of magnets, chemicals, salt and without the need for any electrical power supply.
The SESI works by the use of dissimilar metals placed in the flow of water, being electrically connected. In the presence of water (an electrolyte) a ‘LeClanché’ (battery) cell is achieved. The metals develop an emf (voltage) between them. While a small electric charge is placed on the water species, the main benefit is the addition of zinc metal ions in the water, which produces a permanent change to the calcium crystal morphology. Hard salts are encouraged to cling to each other rather than pipework, heating elements in appliances, etc.
The SESI is a non-polluting method of water treatment and does not alter the water's mineral composition in anyway, so the water still complies with the health regulations laid down by the UK and EU Water Utilities, as well as the World Health Organisation for drinking water.
As the unit does not require a power supply to operate it does not need to be located near to a power socket. The unit will operate efficiently for up to ten years after which it should be replaced.
As this type of electrolytic water conditioning does not rapidly dissipate, the SESI provides long-term protection from limescale and can be used to protect water that is to be stored in a tank.
Over time a thin protective layer will form on the internal pipe surface of the metalwork that prevents the formation of any new corrosion and the build-up of limescale.
It is suitable for fitting to 15mm copper pipe and should be fitted as close to the incoming mains water supply as possible - before any tee-offs.
The SESI begins its process immediately after the unit has been installed. The process is not sensitive to low water flow rates.
 Technical data

Product code: SESI15
Test regulations: (UK) WRAS Certification 0107038 | (Germany) RWTuV Prufprogramm M30/94 Certificate Nr. 2684/95
Materials used: Outer body: copper BS2871 Pt 1 table X. Anode support: grilamid L20G natural. Anode material: pure zinc & magnesium BS6561
Construction: The anode assembly is pressed into the copper body and locked into position. The body diameter is reduced at the ends and brazed to the end connectors. The unit cannot be opened. The SESI (tested to 45 bar) is designed to work to a maximum system pressure of 30 bar treating a mains water supply at between 2-40°C, with a maximum system flow rate of 2m/sec (for silent operation) in the nominal pipe size for the product. The water should have a pH range of 5.0-8.5.
