Frequently asked questions

Q. What benefits are there to installing a limescale and rust inhibitor?

  • Prevention of new limescale deposits and rust formation
  • Remedies existing encrustation/limescale deposits by using the latest technology
  • Longer lifespan of fittings and all machines and devices carrying water
  • Savings on high repair and maintenance costs on all devices carrying water
  • Descaling intervals can be extended with the boiler
  • Up to 50 % saving with detergents and care products
  • Reduced use of specialist cleaners

Q. Are electromagnetic device frequencies harmful?

No, AquaKLEAR limescale inhibitors generate electrical fields (pulses) and are absolutely not dangerous.

Q. Do the systems alter drinking water (premium water quality)?

  • The good quality of drinking water is not altered (coffee, tea and water) because no chemical

additives are required. In contrast, all vital minerals are retained by the water (e.g. calcium, magnesium).

  • Calcium and other minerals are important for your health. They remain in the water. As the liquid no longer retains the otherwise released calcium ions, the water feels softer and soap creates more suds.

Q. How do I know if the system is working?

  • The limescale inhibitor can be equipped with almost unlimited applied programs. They have an automatic control loop (operational readiness check, optimum program setting, constant monitoring, and periodic function tests). They guarantee a proven high degree of effectiveness. Manual settings are not required. The device is fully automatic. A green light on the device shows that it is active.

  • Plumbers will already notice the effect on the condition of the pipes and the device after a few months. (limescale reduction in the pipes of up to 88 %).
