Corrosion Inhibitor for Closed Heating & Chilled Systems – 0024

This product has been replaced by Accepta 2336


Accepta 0024 is a high performance borate-nitrate based corrosion inhibitor scientifically formulated for the treatment of closed re-circulating heating and chilled water systems.

Accepta 0024 is based on a borate nitrite blend, which is suitably buffered to ensure stable pH conditions throughout the water systems.

Accepta 0024 creates a protective film which is maintained on all metal surfaces. This film is kept in constant repair providing the recommended treatment reserve is present in the water at all time.

Accepta 0024 is suitable for use with both ferrous and non-ferrous metals.

Product Benefits

  • Buffered to maintain the required pH value.
  • Non-foaming.
  • Can be used with ferrous and non-ferrous metals.
  • Easy to use liquid.
  • Suitable for LPHW and chilled water systems.

Application & Dosage Information

Accepta 0024 can be introduced to the system by pump to a suitable dosing point, dosage pot or via the system header tank.

The system should be cleaned and passivated prior to the introduction of product to minimise the risk of blockages and the potential for under deposit corrosion.

Providing there is no loss of water from the system, only occasional make up doses are normally required to ensure continuing protection to the system. If make-up water is necessary, this should be dosed at the same treatment level as the initial dose immediately.

It is always advisable to carry out a ‘Control Of Substances Hazardous to Health’ (COSHH) assessment before use.


The normal dosage rate for Accepta 0024 will produce a system reserve of 1250ppm nitrite with a pH greater than 8.3 for most make-up waters.

Where the make-up water has high chloride levels e.g. brackish water, then the normal dose rate should be doubled.

A simple test method is available for checking the concentration of inhibitor present.
