High Performance

Limescale Protection for single appliance and commercial premises

The Liff range of physical water conditioners from BWT work by altering the characteristics of the hardness minerals within the feed water to help prevent limescale forming. Unlike a water softener a scale inhibitor will not soften the treated water and the benefits are derived from the reduction of deposited hard scale within the treated water system.

There are four main types of water conditioner, magnetic, electro-magnetic, electrolytic and electronic. The flexible nature of their design offers the client a range of benefits including low running costs, simple installation and low maintenance. Chemical free operation ensures the composition of the treated water remains largely unchanged, which is particularly important on potable water supplies.

Protection from limescale without salt or chemicals

Phys­ical water condi­tioners use a range of tech­nolo­gies and are avail­able in a variety of sizes. The final choice of model should take into consid­er­a­tion a number of factors including water hard­ness, flow rate, pipe size, pres­sure and system design, as well as the desired quality of the treated water.

The flex­ible nature of their design makes phys­ical water condi­tioners suit­able for a wide range of appli­ca­tions and pipe sizes. It is not uncommon to use more than one type or size of unit to protect different areas of large and complex system and in partic­ular, where the system has a secondary return.

BWT have also devel­oped an addi­tional tech­nique for scale inhibition and control. By using unique, three phase tech­nology, the revo­lu­tionary AQA Total stabilises water by forming nanocrys­tals, making limescale unable to be deposited in instal­la­tions.

POWERMAG Electromagnetic Scale Inhibitor

The Powermag uses the principles of magnetism to inhibit formations of crystalline scale within hot and cold water services. When the untreated water passes through the conditioning chamber, the scale forming elements molecular structure is altered, so that scale-forming particles do not readily precipitate as hard scale forming deposits. Water treated by the Powermag remains potable, so it can also be used in drinking water situations.

WRAPPA Electronic Scale Inhibitors

The Wrappa has been developed to help protect pipes and appliances from the build-up of scale, without the need for maintenance or chemicals. After being fitted to the pipework using the antenna supplied, The Wrappa uses swept frequency radio waves to alter the characteristics of the hardness minerals in the water, helping to reduce scale deposits without altering the composition of the water.

Lime­beater Elec­trolytic Scale Inhibitors

The Limebeater in-line offers a solution to limescale management using an electrolytic principle. They induce an electromagnetic field to change the way scale forms by altering the alignment of the mineral molecules during crystalline formation. Molecules are encouraged to form chains, which develop into sharp thin crystals (Aragonite) which are less likely to form hard, insulating scale than the naturally occurring calcite crystals they replace.

AQA Total Energy 5600 8400 / 11200 14000

The heart of AQA total Energy is the unique bipolar tech­nology: Precisely coor­di­nated current and voltage pulses form tiny limescale crys­tals. These nanocrys­tals stabi­lize the limescale dissolved in the water. Like all other minerals, it remains in the water, but does not accu­mu­late in pipes or boilers.

AQA Nano Limescale Protection

The AQA Nano works according to the proven process of nanocrystal formation. Tiny limescale crystals form as a result of current / voltage pulses. These so-called nanocrystals stabilize the limescale dissolved in the water. Allowing limescale protection in pipes and boilers to be reliably achieved. In addition, drinking water retains the magnesium and calcium that are so important for us.

AQA Total Energy 1500¬ 2500¬ 4500

Our drinking water contains dissolved trace elements and minerals such as magnesium - an important mineral for our body. It ensures energy metabolism and bone formation and gives us energy for everyday life. With AQA total Energy all minerals remain in the water and you automatically ingest valuable calcium and magnesium with your drinking water - day after day, simply with every sip of water.
