The HydroMAG® range of products has offered superior performance for the control of scale in water heaters since their introduction into the UK over 20 years ago. During this period, there have been several technological innovations by water heater manufacturers to increase the thermal performance of their equipment and to signifi cantly reduce the carbon emissions produced by it.
A HydroMAG®-T Duplex wall mounted advanced physical water conditioning system The introduction of high efficiency water heaters has brought with it significant additional technical challenges for physical water conditioners and these are most comprehensively addressed by the introduction of the HydroMAG®-T. The HydroMAG®-T is a physical water conditioner capable of offering softener like performance under arduous and stressed conditions.
The Physical Conditioning Process
For a full understanding of the physical water conditioning process, please see the section marked ‘Physical Water Conditioning’, in the scale control page of this website. Like all physical water conditioners, the objective of the HydroMAG®-T is to create ‘seed nuclei’ or microscopic scale particles. It is these nuclei that will ultimately prevent the formation of scale in the water heaters and throughout the continually wetted areas of the water system itself, thus the creation of seed nuclei is of paramount importance. The HydroMAG®-T has been specifically designed to maximise this effect and has been optimised to produce a harvest of seed nuclei, distinguished by their number, size, strength and physical attributes, which produces a water conditioning so effective, that to date its performance can only be matched by conventional base exchange water softeners.
The HydroMAG®-T Water Conditioning Process
The HydroMAG®-T, unlike its sister product, the HydroMAG®, does not use an electromagnetic field to create its conditioning effect. Instead the HydroMAG®-T utilises the cathodic reaction in a hybridisation of electrochemical and electrolytic principles to produce the seed nuclei. The process occurs in a water conditioning module, specifically designed and engineered for this task.
The active conditioning module is a composite of high tech materials, some developed for the application and others used in novel ways, all have been approved by WRAS for use in domestic water systems. The module is housed in a stainless steel water conditioning vessel.
The picture to the right shows a section through the HydroMAG®-T advanced physical water conditioning system. The control electronics of the HydroMAG®-T are programmed with the water quality parameters for the water being treated, where significant variations in water quality are envisaged (as the result of water gridding for example) then the unit can be equipped with an in-line sensor to take account of this variance automatically. The output of the HydroMAG®-T is responsive to the water flowrate entering the unit by the incorporation of a water meter in the design.
By the use of both water quality parameters and system flow measurement, the HydroMAG®-T tailors its output in order to ensure optimally conditioned water at all times and hence the superior operating performance achieved. An additional benefit of this control technology is that the service life of the active conditioning module will also be optimised.
Hydrotec have always believed that one of the most important functions of a physical water conditioner is to protect the water heating equipment. Never has this been more important than since the advent of modern high efficiency water heaters, not only to prevent the loss of a capital asset but of equal importance, to ensure continuity of service for the end user in the support of their business or service requirement.
No other physical water conditioner can provide the softener like performance of the HydroMAG®-T As a result of this, most water heating systems can be successfully treated by the inclusion of a HydroMAG®-T in the design; such water heating devices include:
- High efficiency water heaters
- Low water content
- Very high heat flux densities
- Small water ways
- Water inside the tubes
- Complex control systems
- Electrically heated systems
- ‘Challenging’ sites
- Plate heat exchangers
The key benefit of physically conditioned water over all forms of other treatment regimes is that the water is not chemically modified in any way. This is important as it means that wholesome water treated by this method remains drinkable and can be used without restriction in all processes that normally require mains quality water.
It is a widely acknowledged statistic that just 1mm of scale on a heat transfer surface will reduce the thermal efficiency by 7%; this will have a corresponding effect on both the operating costs and carbon dioxide production. The importance of operating costs will be a key metric by which system operators will assess the performance of their high efficiency water heaters, thus conditioning systems enabling these units to operate at their optimum levels will be vital.
However, carbon dioxide production is of equal importance. We all have a duty to minimise our carbon footprint wherever possible and this is one area where it is of critical importance. Failure to protect any water heating equipment from scale formation can add significantly to the carbon cost of the system. Failure to protect a high efficiency system also undermines the original rationale for the selection of this type of equipment.
Physical Water Conditioner Selection
For each project where scale control may be considered, Hydrotec will provide a water analysis service, via our inhouse laboratory, to ensure that requirements of the water treatment regime can be accommodated. This will ensure that your HydroMAG®-T provides excellent performance and value for money operation.
Moreover, the HydroMAG®-T range is designed in a range of sizes, for different flowrates and process requirements. All units are supplied with BMS compatible controllers to enable simple and effective monitoring, ensuring continuous system protection.
Statutory and Performance Approvals
As you would expect the HydroMAG®-T has full compliance with regulation 4 of The Water Supply (Water Fittings) Regulations 1999 for England and Wales, The Water Bylaws (2004) for Scotland and The Water Supply (Water Fittings Regulations 2009 for Northern Ireland and this is demonstrated by the achievement of WRAS approved product (approved fitting) status for all the units in the range.
However, WRAS approvals, whilst necessary do not give any indication of the unit’s performance, so are of little help when making a purchasing decision. Fortunately there is a performance standard available in Europe from the ‘Deutsche Vereinigung des Gas und Wasserfaches’, better known as the DVGW which is Germany’s Association for Gas and Water standards and whom, under their technical and scientific division, have developed the world’s most stringent performance test for physical water conditioners. The HydroMAG®-T has been assessed and passed the W512 test for physical water conditioner performance, so you can be assured that the HydroMAG®-T will deliver the performance you require.
The performance of the HydroMAG®-T system has not only been proven under laboratory conditions, but is also backed by extensive field trials, conducted under arduous conditions over an extended period, often amounting to several years, where previously the water heating equipment could only be operated for a matter of months before failure.
Use of the HydroMAG®-T should be considered where:
- The water quality would indicate that scale formation is likely
- Maintenance of wholesome water is required
- Compliance with the HSE’s Approved Code of Practice, L8, for the control of legionnaires disease is required
- Compliance with building regulations is required
- Value for money treatment is desirable
- Low Energy consumption is needed
- There is the desire to protect high value capital assets from scale formation
- There is a need to maintain the performance of water heating equipment to maintain fuel bills and carbon emissions at the lowest possible levels.
- BMS connectivity is required
- Very low maintenance is desirable
- A high degree of environmental compliance is needed, such as the achievement of a BREEAM rating
