It has been proven in practice that using the product to clean and etch heat exchangers substantially improves their heat exchanging efficiency. The improvement in the reliability of these devices can be achieved by elimination of expensive repairs, which often include replacement of malperforming elements of the cooling system. The largest effects are achieved by heating the bath solution to 50°C with the continuous solution flow. In these conditions the solution practically does not affect acid resistant steel or rubber seals, and has only a minuscule effect on standard grade steel (corrosion speed under 0.2 mm/year). The cleaning process must be monitored by measuring the acidity and pH of the solution. The product has been approved for industrial use while observing basic work safety measures. Bioruster obtained the Hygiene Certificate issued by the National Institute of Hygiene. (Hide)

The attached video shows the process and results of boiler scale removal from a section of pipe cut from a heavily contaminated heat exchanger. The demonstration was done in laboratory conditions.

The choice of product depends on the physicochemical composition and the structure of the sediment and on the material to be cleaned, usually diluted 1:5 to 1:20 with water. It is produced as a concentrate. Cleaning of the complete central heating installation does not require removal of heat exchangers, radiator flanges, radiators and other components, there is also no need to neutralise and passivate the surfaces after cleaning.

For the best results the cleaning bath should be heated to 50°C and the solution should be continuously circulated. The cleaning process should be monitored by periodical measurement of acidity and pH, and possibly the conductivity, of the bath. At the end of the process the used bath should be neutralised with sodium hydroxide or hydrated lime and be disposed of the in the sewage system only after reaching pH = 6,5÷7 and diluting with water. The final stage is thorough rinsing of the equipment and installation with water until the out-flowing liquid is clear, colourless and pH-neutral.

Chemical cleaning with BIORUSTER products guarantees restoring the central heating installation to its original condition, and also protects all automated steering and control equipment from sediments and corrosion products. Therefore its preventative application actually extends the installation lifetime and restores the heating comfort, and in cases of planned upgrading and automation assures its problem-free operation. Additional advantage is no discomfort for the inhabitants as the procedure can be performed during the heating season without disconnecting the installation, in a relatively short period of time.

The need for chemical cleaning of central heating installations is due to many reasons. One of the problems facing housing-stock managers is a poor condition of the installations, the consequence of many errors in the past with the construction, lack of proper materials and fittings, and the absence of standards and regulations which would assure the creation of durable and energy-saving heating systems. Irrespective of the chemical composition and structure of the sediments in the central heating installation, they cause significant operational disturbances, such as the decrease of the flow section and increase of the pipe coarseness, thus increasing the flow resistance. .

As a result, the heat transmission coefficient, and the efficiency, of heat exchangers decreases, more energy is needed, the temperature of radiators and of the heated areas drops, and the post-sediment corrosion risk increases.

The most serious damages caused by the sediments are done in fully or partially automated central heating installations, in particular break-downs, seasures or loss of water-tightness of the automation components. The sediments affect primarily flanges and valve seats, thin bellows, ball or pipe valves and flanges in regulator valves.

Research done by the Warsaw Polytechnics and the experience of firms converting central-heating installations and heat exchangers to automated operation show that many such automated control and steering systems require repairs or replacement after only a few months of operation.

The firms which after training gained licence certificates for chemical cleaning are spread all over the country, thus assuring access to professional and safe services . Housing co-operatives train their own brigades in our technology, thus reducing the cost of bringing the central-heating installation back to its peak functionality.(Hide)
