Calmag Cal Combi Magnetic/Electrolytic Scale Reducer

CalCombi is a totally unique scale inhibitor that combines two scale inhibiting technologies into one. The CalCombi  first technology is the use of a magnetic bar to induce a single polarity into the water. This causes the calcium and magnesium (limescale) particles to take on the same polarity. The particles then repel each other, and as a result prevent the formation of hard limescale. The CalCombi second technology is the use of zinc plates which create the same reaction as a magnet. Once water passes over the CalCombi plates and the inner copper body of the unit, a single polarity is induced into the water supply. This then prevents the formation of hard limescale. In addition, the zinc plates slowly release minute particles into the water supply which prevents corrosion by removing all the air in the system. CalCombi can be fitted in two places. The  first is on a central heating system to stop corrosion and the second is on cold water mains to prevent the formation of hard limescale.

CalCombi is also suitable for fitting on both 15mm and 22mm pipework, making it very versatile. The CalCombi unit is supplied with push-fit fittings, making it very simple to install! Once the unit has been installed you can sit back and relax as it will continue to work day and night without the need for regular maintenance.
