What is PTH and how does it work?
PTH stands for Protection against Total Hardness.
The PTH Water Conditioner is made of two parts, a cylinder made of stainless steel and an inner core of an alloy made of noble and semi-noble metals. When water flows through it, weak electrical fields are produced by electric potential difference between this patented alloy core and the metallic cylinder. These fields and the venturic effects stemming from the unique configuration of the core prevent the adhesion and cohesion of the waterborne mineral particles – mainly carbonic salts, calcium and magnesium.
In other words, the ions lose their polarity and become neutralised, so that they do not cluster together to create limescale, salt and carbonates. The molecules are re-arranged and are not in close contact with each other any more. This is what is called the ‘wetter water’ effect, a phenomenon unique to PTH. In addition, scale binders such as silica, alumina and calcium sulphate are broken down when hard water enters the cylinder and flows over the specially designed 12-part alloy core with its embedded flow lanes.
Basically, the PTH ‘scrubs’ the water. This is a completely natural process and occurs freely in nature when, for example, a stream or river flows over a bedrock containing just 2 or more different types of metals or noble or semi-noble minerals. It is an entirely ‘green’ product which will not harm the environment; in fact, it is good for it.
What is also important is that when the PTH treats water, mineral salts such as calcium and magnesium remain in the water to benefit the people using the water but, as they are rendered harmless, they do not cause problems in their household appliances or geysers. And, like a natural stream, the taste is improved.
The PTH system requires no maintenance [other than a quick brush with a wire brush every 9 months or so (the inner core is easy to remove and re-insert)], needs no chemicals, uses no electricity or any other power source and will last a lifetime. In other words, it is a once-off cost…forever.
Users will enjoy lifelong service from the PTH, with no chemicals, no electricity and the barest of maintenance.
It is also unbreakable. PTH is endorsed by Stellenbosch University, UCT, North West University (Potchefstroom), Ben-Gurion, the Protea Hotel Group, Spilhaus, Witzenberg Irrigation and countless leading institutions and captains of industry in South Africa and world wide, of which a few include Samsung, Kelly Marine, Anglo-De Beers, Polyoak, Sanlam, Marlin Granite and Naspers.
The PTH comes in different sizes. The correct size depends on the water flow rate. It is measured in liters per minute – see ‘Selecting the right size PTH’. It comes with full installation instructions, and is straightforward and easy to install.
