The precipitated calcium carbonate crystals absorb some of the polyphosphate liberated by the AQUAFOS which hinders their aggregation to form scale.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCORROSION\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCorrosion is prevented by the presence of phosphates and silicates which form a very thin protective film on the metal surfaces which, whilst protecting the metal, does not impede or reduce heat transfer. A concentration of 3 – 5 ppm (mg\/litre) of AQUAFOS is sufficient to prevent both scale and corrosion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSCALE REMOVAL\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWhilst the main purpose of AQUAFOS is to PREVENT scale formation it has been found that the continuous use of AQUAFOS will, over a 9-to-12-month period, remove existing scale deposits. This removal is influenced by the age and composition of the scale. PLEASE NOTE:1mm of scale on a heating coil or geyser element will increase the electricity costs by 15%. \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES \u0026amp; BENEFITS\u003c\/strong\u003e \u003c\/p\u003e\u003cp\u003e*Freedom from scale problems. \u003c\/p\u003e\u003cp\u003e*Protection against corrosion. \u003c\/p\u003e\u003cp\u003e*Saving in energy consumption – better heat exchange – no scale insulating layer. 1mm of scale increases the energy consumption by +- 15%.\u003c\/p\u003e","brand":"Aquafos","offers":[{"title":"Default Title","offer_id":54499171238201,"sku":"100400955","price":272.25,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0910\/0243\/7945\/files\/100400955__20260918142918_bb26db07.png?v=1789734608","url":"https:\/\/shop.nwk.co.za\/products\/crystals-for-crystal-descaler-pack-1kg-400955","provider":"NWK Shop","version":"1.0","type":"link"}
