"rb bertomeu" belim CAL De-encrustant
 Since February 2000

Formulated specifically to eliminate calcareous encrustation (calcium carbonate) in installations of carbon steel, stainless steel, copper and their alloys , guaranteeing an energetic attack on the encrustation and correct protection of the indicated materials.

PRESENTATION  : Plastic containers of 25 Kg .

The product is manufactured from a base of various organic and inorganic acids and corrosion inhibitors.

The product is very useful for cleaning the exterior parts of the coils and/or plates of refrigeration towers which  use water as liquid cooler in a closed or semi - closed circuit. In this case , or other similar industrial applications , the surface of heat exchanger parts (coils or plates) becomes covered with calcium carbonate caused by the action of heat and the increase in concentration due to the evaporation of the water, in spite of the fact that decalcified water is used. With time, the thermal exchange capability is reduced to levels which make cleaning of the equipment absolutely necessary. Nevertheless , it is advisable to carry out periodic cleaning to avoid reaching levels of serious encrustation.


The product can be used concentrated for cleaning specific zones , but it is advisable to use it diluted in water by 10 - 20 % . Maintain the solution in circulation , through pumping , for several hours until the total removal of the encrustation.

The consumption of belim CAL  will depend on of the quantity of calcium carbonate to be dissolved . The pH  of the wash liquid must be controlled (it must be always be below 4 ) to know if the acid is exhausted and cleaning solution needs adding. When finished , wash with water to eliminate the acid remaining in the equipment.

After cleaning neutralise the residual acidity of the liquid of wash with lime , or other basic products , before sending it to the station waste water purifier.
