Application & Dosage Information
Dose Accepta 2501 to give sulphite reserves in the boiler of approximately 50ppm.
Note the dose rate will depend on the feedwater temperature. It is recommended to dose at a rate of 18ml/m3 for every ppm of dissolved oxygen.
Monitor sulphite levels regularly.
Dose Accepta 2501 with a positive displacement pump to the point of application.
Accepta 2501 is compatible with other boiler water treatment products.
Do not allow this product to mix with strong oxidising agents or acids.
It is always advisable to carry out a ‘Control Of Substances Hazardous to Health’ (COSHH) assessment before use.
Titrate with potassium iodide / iodate solution in presence of an acid starch indicator.
On-site, measure sulphite using an Accepta sulphite drop test method to comply with BS 2486.
