Q. Has KAL-GUARD+ been thoroughly tested?

A. Yes, the electrolytic action of KAL-GUARD+, using a zinc anode, has been tried and tested over many years in a wide range of applications. Building on the success of the original KAL-GUARD, KAL-GUARD+ incorporates electronic controls to synchronise the release of zinc to the hardness of the water. Tests at Cranfield University have confirmed that KAL-GUARD+ reduces limescale formation by up to 80% compared to non-treated water and these results have been borne out in extensive field trials.

Q. Is it safe to put zinc into the water?

A. Zinc is a naturally occurring mineral which forms an essential part of the human diet. It is found in high levels in grains and pulses and is one of the reasons these foods are considered beneficial to health. The levels of zinc released by KAL-GUARD+ are relatively low, even at maximum dosage, and will not affect the taste of the water.

Q. Will KAL-GUARD+ remove existing scale deposits?

A. Tests at Cranfield University (click here to see results) showed that
KAL-GUARD+ will remove existing scale deposits as well as preventing the formation of further limescale. However, if your system is badly scaled we would recommend thorough descaling prior to fitting the KAL-GUARD+ in order to achieve the full performance benefits in the minimum time.

Q. Does KAL-GUARD+ soften the water?

A. No, KAL-GUARD+ is not a water softener. Water softeners remove calcium salts from the water,
Kal-Guard+ does not remove these salts but ensures they do not settle onto surfaces as limescale.

Q. Is KAL-GUARD+ easy to fit?

A. KAL-GUARD+ is very easy to fit, as it is plumbed in line to the system. Even when retrofitting to an existing system, only two simple cuts to the pipework are required.

Q. What are the maintenance requirements for
KAL-GUARD+?

A. KAL-GUARD+ only requires occasional visual inspection of the control display to confirm the unit is functioning properly.
