Closed System Chemical Cleaning Agent

Description and Use

ACCEPTA CORROSPERSE 84 antifoulant is a non-acid blend of sequestering and dispersing agents for the removal of iron oxide, other metallic oxides and scale deposits from open and closed loop systems. It may also be used continuously at low levels to prevent deposits forming.  

Dosage Rates

For pre-commission cleaning, a concentration of 1-2% by volume should be used and circulated within the heating system for a minimum of 2 days and a maximum of 7 days. 

For closed system restoration cleaning a concentration between 2.5-5% is normally required, dependent on the degree of fouling. The length of time required to effect a clean will again depend on the degree of fouling and the progress of chemical reactions can be monitored by simple on-site test methods or by postal samples to Accepta. 

Warning

Whilst not aggressive to the parent metal ACCEPTA CORROSPERSE 84 is a powerful penetrant and will find any weakness in pipework or joints which is simply sealed by a layer of corrosion products. It is recommended therefore that in the restoration of old systems that an initial concentration of 1% only be added and circulated for 2 days to ensure system is sound before proceeding further. 

When cleaning a system containing Aluminium in conjunction with Copper a supplementary treatment – ACCEPTA 2334 should also be added at the rate of 1 litre/m3 of system capacity.
