Corrosion Inhibitor for Closed Chilled & Low Pressure Heating Systems

Corrosion Inhibitor for Closed Chilled & Low Pressure Heating Systems

Accepta 2308 is a high performance water treatment product scientifically formulated using a blend of organic and inorganic corrosion inhibitors that offer the ideal treatment for closed chilled water and low pressure heating systems.

NOTE: This product is no longer available and has been replaced by the following alternative:

Accepta 2340

If you require product selection assistance or technical advice please contact us.


Although unsuitable for use in systems containing aluminium, Accepta 2308 is particularly effective in protecting steel, copper and other non-ferrous metals.

With the added benefit of lower dosing rates than the more traditional nitrite-borate based corrosion inhibitors, Accepta 2308 raises the system TDS to a much lesser degree.

Application & Dosage Information

In systems requiring significant passivation higher initial dosages may be required to yield the required nitrite residual.
