EC Electromagnetic water conditioner WRAS approved, scale-reducing electromagnetic water conditioner
EC Electromagnetic Water Conditioner Introduction Electromagnetic Water Conditioners Explained It is widely known that calcareous scale build-up in all domestic and industrial plant causes considerable damage and high operating costs including: Inefficiency of pipework Deterioration of pipework and consequent leakage Greater power consumption and lower efficiency of domestic appliances such as boilers and dishwashers etc Inefficiency of boilers in the production of hot water Inefficiency of heat exchangers both in stand-alone boilers and centralised heating plants Inefficiency of cooling equipment used in refrigeration Why does scale build-up occur? Water from both the mains supply and natural sources (such as boreholes) contains minerals that are vitally important contributors to good health and wellbeing. One of these elements is calcium bicarbonate, which along with magnesium and various other dissolved salts contributes to the level of hardness of water. As water temperature is increased, the inherent calcium bicarbonate [Ca(HCO 3 ) 2 ] releases carbon dioxide [CO 2 ], leaving calcium carbonate [CaCO 3 ], the cause of limescale build-up. The orthorhombic structure of aragonite crystals has a low level of aggregation and adhesion, preventing calcareous scale build-up. Extensive testing has proved that the innovative distribution of the electromagnetic forces within the Dutypoint EC unit ensures that the calcium carbonate in the water downstream of the unit forms only as aragonite (see right). Therefore, although the chemical composition of the water is not changed, the Aragonite Crystal - low level of aggregation and adhesion. aragonite crystals generated have a low level of aggregation and adhesion preventing calcareous scale build-up. The unit is WRAS approved, demonstrating that potable water upstream remains free from contamination downstream. In practice, this change in crystalline structure prevents the build up of scale in plant room equipment. The two images below illustrate the effects of the water conditioner: Ca(HCO 3 ) 2 CaCO 3 + CO 2 + H 2 O What is an electromagnetic water conditioner? Water conditioners are the ecological solution for overcoming the lifecycle cost associated with the build-up of hard limescale in water systems. An electromagnetic water conditioner reduces the energy consumption and extends the life of equipment by eliminating the build-up of hard calcareous limescale, without introducing harmful chemicals or additives. Treating hard water with a water conditioner ensures that the quality of the water is maintained; none of the essential minerals present in potable drinking water are removed through the treatment. How does a water conditioner prevent scale build up? Calcium carbonate commonly occurs in two different crystal structures, calcite and aragonite. Although calcite and aragonite have the same chemical composition, their crystal structures are completely different: The trigonal structure of calcite crystals has a high level of aggregation and adhesion (see right), causing rapid calcareous scale build-up within pipes and connected equipment. Calcite Crystal - high level of aggregation and adhesion. How is an electromagnetic water conditioner different from a water softener? Electromagnetic water conditioners, which are also known as a type of physical water conditioner, are becoming the preferred option in the majority of installations over water softeners because they do not alter the chemical composition of the water, or introduce any chemicals into the water. As a result, there is no requirement for a separate softened water supply - if drinking water is passed through a Dutypoint EC it retains its quality downstream of the unit. No chemicals are added and no essential minerals are removed - this also means that there are no chemicals to replenish. The unit is WRAS approved, illustrating that no contaminants are introduced to the water. This results in significant cost savings when compared to installing a water softener. 2
