DBR 80
Description: DBR 80 is a chemical product containing alkaline elements, sodium sulfite, polyacrylates, surfactant agents,
organic phosphates and triazoles. It is proper for a curative treatment and mud removal operation for central
heating plants and other closed circuits. DBR 80 allows for dispersion of concentrated metal oxides that were
formed by the calcium carbonate. It protects the attacked metals (copper, cast iron, iron) bilding an oxygenreducing
environment. The product can remain in the pipes until a normal water circuit and purity is achieved.
The impurities removal with DBR 80 can last many months without damaging the heating pipes. In this way the
curative and preventive treatments connect. DBR 80 is an alkaline product and it cannot be used for aluminium
parts (alloys or derivates).
Physical and chemical properties: - ready to use fluid
- pH-value: alkaline
- density at 20ºC : 1,12
- alkalinising , causes dispersion and dissolution
- oxygen and carbon dioxide reducing
- copper and iron corrosion inhibitory effect
Usage: In large installations: The dosage varys by the residue quantity. The medium concentration of DBR 80 must be between
1 and 3 %. The pH-value must be kept at 10 during the treatment. The product can be introduced with the help of a
dosing unit or an injection pump. The installation must be equipped with evacuation valves at the bottom of the columns,
decantation tanks or magnetic filters (CLARIMAG) , in order to evacuate the DBR 80 dissolved and liquefied residues ,
that are in the circuit and that need a concentration reduction in order to purify the pipe water.
In small installations: with the help of a TUBNET pump the product can be circulated, with a dosage of 6 to 10 % or it
can be introduced in two phases with a concentration of 3 to 5% and rinsing inbetween. A collecting decanter of
CLARIMAG type can be installed.
Control for 10 kg of DBR for m³:
- pH-value: 9,5 - 10
- 10 kg SO 3 reduce 20 g for m³ of dissolved oxygen
- P 2O 5: 35 mg for l
Recommendation: The removal of residues with DBR 80 is ideal for large installations equipped with a magnetic capture device,
that remove oxides and prevents mud depositing.
The operation shall take place in winter and the installation will be progressively improved.
Attention: Operation mode.
Preliminary condition: Before treatment any installation must be checked for deaeration system and for functionating valves.
The total state of the installation must also be controlled in order to evaluate the leaking risks, but also to
check internal and external pipe corrosion (when passing through walls and floors ), radiators
(environmental humidity), zones with bad circuit (also obstructions), tap or valve blocking, etc.
Important: The treatment removes incrustation and suspending oxides and carbonates .
The used products protect installation elements but water loss when removing mud by chemical treatment must be
taken into account.
1. Complete evacuation of pipes
Note: This may not always be possible for large installations.
2. Filling and introducing DBR 80 - quantity according to the installation size . Checking the circuit. Measuring the
pH-value during the conditioning, must be about 10. Evacuation by opening the valves at the bottom of the columns
or by magnetic capture and heat distribution check. Check the liquidity of the thermic fluid .
3. When the installation heats all over and the fluid is pure, the evacuation and rinsing is necessary , then manipulate
the radiators’ taps in turn in order to obtain a preferred circuit and check the pH-value that must be around the
neutralisation value.
4. It is recommended to introduce the corrosion inhibitory agent.
Reservation: Exclusive professional usage. See security data sheet.
Packaging: 10 l can with Ref. no. 7509 or 20 l can with Ref. 7511.
User recommendation: Product for professional usage according to instructions. We do not assume any responsibility in case of
inexpediently use of the product.
