Technical characteristics and composition

ROCAL Acid Multi is an acid-based formulation with corrosion inhibitors that effectively acts on deposits without damaging system components. Its balanced chemical composition quickly dissolves limescale, metallic oxides, and organic residues that compromise the optimal functioning of thermal systems. The product is compatible with various materials commonly found in systems, including copper, steel, brass, and acid-resistant synthetic materials.

Main applications

This professional descaler is used in numerous system maintenance contexts:

• Cleaning of wall-hung and floor-standing boilers with copper, steel, or aluminum exchangers
• Descaling of domestic hot water boilers and tanks
• Maintenance of plate or tubular heat exchangers
• Cleaning of industrial cooling circuits
• Treatment of radiant floor or wall heating systems
• Restoring the efficiency of fan coils and heating terminals

Operational advantages

Regular use of ROCAL Acid Multi offers numerous benefits to the treated systems:

• Restoration of full thermal efficiency of heat exchangers
• Reduction of energy consumption thanks to improved heat transfer
• Prevention of failures caused by localized overheating
• Elimination of noise and vibrations due to deposits in the circuits
• Extension of the service life of system components
• Improved circulation of the heat transfer fluid

Instructions for use

The product can be used neat or diluted in water in variable proportions from 10% to 30% depending on the degree of scaling. For optimal action, it is recommended to circulate the solution in the system for a period between 20 minutes and 2 hours, monitoring the descaling process. At the end of the treatment, it is essential to rinse the system thoroughly with clean water until the pH is neutralized. To facilitate the descaling operation, Rothenberger recommends using its ROCAL 20 or ROCAL Acid Plus flushing pumps.

Safety and storage

ROCAL Acid Multi must be handled with appropriate safety precautions, wearing protective gloves and glasses during transfer and application operations. The product should be stored in its original container, in a cool, dry place, away from heat sources and out of reach of children. The 10kg package ensures a long operating autonomy for professionals who carry out frequent maintenance interventions on heating systems.
