Corrosion Inhibitor for Heating Systems Afriso BCI 500 ml — treats up to 100 L water / 120 m³ underfloor heating / 10 radiators

Afriso BCI corrosion inhibitor is supplied in a 500 ml bottle formulated for closed heating systems. The product is designed to protect metal components against corrosion and to reduce lime deposit formation, helping to maintain heat transfer efficiency and prolong system service life. One bottle treats up to 100 litres of system water and is also specified for typical installations such as up to 120 m³ of underfloor heating or approximately 10 radiators. The product has a shelf life of 2 years from the date of production.

Advantages

Afriso BCI provides protective film-forming and inhibiting action on ferrous and non-ferrous metals used in heating circuits, limiting electrochemical corrosion and slowing scale formation. By preserving clean heat-exchange surfaces it supports steady thermal performance and reduces the need for early component replacement or system flushing. The dosing concentration and coverage are suitable for both small radiator systems and larger underfloor heating installations, offering a single-component treatment that is ready to use and simple to dose.

Suitable for

• Closed central heating systems with radiators
• Underfloor heating circuits up to the stated volume
• Mixed-material systems containing steel, copper, brass and aluminium components

Key specifications

• Net volume: 500 ml
• Treatment capacity: treats up to 100 litres of system water
• Equivalent coverage examples: suitable for underfloor heating systems up to 120 m³ or approximately 10 radiators
• Function: corrosion inhibition and lime-scale reduction in closed heating circuits
• Shelf life: 2 years from production

How to use

Introduce the required quantity of Afriso BCI into the heating system via a system filling point, expansion vessel drain or dosing valve according to the treated water volume. Ensure the system is at normal operating temperature and circulation is active during and after dosing to distribute the inhibitor evenly. For best results, verify the system water quantity and add the appropriate number of bottles or corresponding fraction to achieve the recommended concentration. Follow any additional instructions on the original product label regarding safety and handling.

Usage recommendations

Before adding inhibitor, inspect the system for active leaks and repair them. For systems with significant existing deposits or corrosion, a professional cleaning or flushing is recommended prior to chemical treatment. Re-check inhibitor concentration after major servicing or water top-ups and re-dose as necessary to maintain protection.
