SYSTEMS OF ELECTROCHEMICAL CORROSION PROTECTIONHot and cold tap water, central heating and technological heat installations are especially the subject to the destructive activity of corrosion. In Poland it attacks the water pipelines and equipment at extremely fast and aggressive way, causing their reduced efficiency and increasing the probability of their failure in short period of time. This leads to a total loss of such installations and to a necessity of their expensive and burdensome replacement. In fact the water installations are the most threatened field of the building industry's infrastructure, due to their highly expensive and frequent need of reconstruction. However, we are not helpless in the face of corrosion that attacks and destroys the hydraulic systems. Since many years the Specialistic Enterprise of Corrosion Protection LEMAT can effectively protect them by launching the highly efficient and reliable SYSTEMS OF ELECTROCHEMICAL CORROSION PROTECTIONThe systems of electrochemical corrosion protection are the most reliable and effective means of prolonging the vitality and exploatational efficiency of the hydraulic systems in the Polish building industry. In this method we take advantage of the electrochemical processes by applying the aluminum anode in an especially designed reactor. All the programmed reactions are controlled by the polarizing device. The protective effect of the electrochemical processes applied by LEMAT on the hydraulic systems has two ways of action: firstly - the quality of the water is improved, treated water is thus less corrosive in causing corrosion. Consequently, the speed of the corrosion is drastically decreased; secondly - inside the pipelines an elastic protective layer is created, effectively isolating the installation from the corrosive factors. The protective layer secures the installation from corrosion and creating boiler scale and helps to retain the clarity of the sections and full efficiency of the installation for many years. The effectiveness of this corrosion protection system is shown on the sections of the pipelines pictured below. These sections were cut from the installations, which are subject to everyday intensive attacks of corrosion and from the installations protected by the LEMAT electrochemical systems. SECTIONS OF PIPES CUT FROM THE WATER INSTALLATIONS IN WARSAW AFTER 5 YEARS OF EXPLOITATION.
The protective layer is made on the base of aluminium hydroxide and is characterised by strong absorbing abilities. Thanks to these abilities the layer can bind and remove from the water a large amount of harmful and unwanted iron compounds and heavy metals ions. This method is irreplaceable, the most efficient and incredibly effective. The systems of protection used by LEMAT allow us to extensively prolong the vitality of the installation. LEMAT PROTECTIVE SYSTEMS PREVENT CORROSION, PROTECT GREAT PROPERTY, ALLOW TO REDUCE THE COSTS OF EXCHANGING THE INSTALLATIONS AND TO REDUCE THE COSTS OF EXPLOITATION. Every hydraulic system can be protected from corrosion by the systems of electrochemical protection, but, naturally, the protection is the most efficient if the installations are new and not afflicted by the effects of corrosion. The best effects characterise the most frequently applied LEMAT corrosion protection systems of the central heating and hot and cold tap water systems.

All the new central heating systems ought to be equipped with the systems of electrochemical corrosion protection. There is also a possibility to save and prolong the efficiency of the installations already being exploited, after they had been cleaned with specialistic technologies. Complex thermorenovation service ELECTROCHEMICAL CORROSION PROTECTION DEVICE IN HOT AND COLD WATER SUPPLY SYSTEMThe major weakness of the metal installations is their big susceptibility to corrosion. This concerns the hot tap water pipelines, because in the temperature over 50°C the corrosion processes are quickened. That is why metal installations require a durable and reliable strengthening to make them stay in good shape for a longer period of time. The LEMAT corrosion protection systems are a guarantee of such reinforcement. They find application mainly in the installations made of galvanised steel, copper and also in the systems of pipelines made of plastic with some elements and equipment made of metal.
An important virtue of the electrochemical method applied by our firm is a noticeable improvement of the physico-chemical properties of the tap water. The LEMAT systems of protection condition the water, making it more soft, less aggressive in causing the corrosion and to a large extent cleared from unwanted iron and heavy metals compounds. Thanks to that, the taste of the meals improves, as well as the quality of the washing and the durability of the household appliances ( such as a kettle or a washing machine). The systems of protection have also a positive influence on the durability and reliability of the technical equipment that is connected to the water installations in the building. The LEMAT systems are equipped with a unit of automatic regulation of the processes of protection and the level of aluminium in the water. This assures that the concentration of aluminium in the water is always the same and it can be controlled, regardless to the flow level of the water.

The LEMAT systems of electrochemical corrosion protection are effective, reliable and extremely efficient. That is why they are irreplaceable in every rational plan of creating or modernising any tap water installation. Relatively low costs of installing the systems of protection bring great benefits: multiple prolongation of the pipelines vitality, durability and reliability of the expensive technical equipment, decreased probability of its malfunction and less frequent need of the conservation and reparation works. All these factors allow the full return of the money spent on the investment and the economical costs of exploitation. THE MONEY SPENT ON THE LEMAT CORROSION PROTECTION SYSTEMS IS THE MOST REASONABLE INVESTMENT IN THE POLISH BUILDING INDUSTRY
