1.1 General Information
The elector systems are used as reaction devices for the electrochemical treatment of heating water as part of a
chemical-free operation of heating systems. Electrochemical water treatment contributes to a water quality that
is unlikely to cause damage from the formation of limescale and corrosion in heating systems.
The functional parts are made of stainless steel, brass fittings, a high-potential magnesium alloy and high-
quality plastic parts. The reaction device is made of stainless steel. As sealing materials age-resistant
elastomers, hemp and ararmide fibers (KLINGERSIL C-4400) are used. The insulating material is high-quality
flexible PU foam or high-quality non-woven fabric of fire class B1. The materials used comply with the
recognized rules of technology.
The instructions in this user manual enable you to operate the system safely, properly and economically. In
particular, basic instructions for installation, operation and maintenance must be observed.
Any person who works with this system must read these operating instructions and observe and apply the
instructions listed.
In addition, the manufacturer of the reaction vessel recommends to keep a written documentation on site.
You can use the form at the end of this user manual.
These operating instructions must always be available on site.
1.2 Field of Use
elector reaction devices are used for the electrochemical treatment of water as part of a chemical-free corrosion
protection in systems with closed water loops, such as heating systems. They are used to achieve effective
corrosion protection through ideal water quality without the addition of additional chemicals, to remove existing
circulating impurities and to prevent the formation of new corrosion products.
In particular elector systems are used in heating systems, in which there is an increased risk of corrosion
due to constant ingress of oxygen, as it might be found eg. in underfloor heating with non-diffusion-protected
plastic pipes. Furthermore, the use of the elector systems preferably takes place in low-temperature systems
(for example heat pumps) or in the context of the so-called low-salt operation of heating systems, primarily for
stabilizing the pH.
Corrosion in heating systems is always caused by an interaction of several factors. elector reaction devices
are not a standalone corrosion protection device. We understand it as a measure in the overall context of plant
operation. Due to its positive effect on the heating water, an elector system decisively contributes to a chemical-
free corrosion protection through natural formation of protective layers on the surface of metals and passivation
of the metals in the system. The core functions are:
• Scavenging of dissolved oxygen by electrochemical reaction.
• Removal of ciculating air bubbles.
• Increase of the pH value >8.3 by electrochemically generated hydroxide.
• Separation of circulating contaminants from the system water.
